Challenge Match - Jazlene vs. Phillip - Board 8

I'm still trailing by seven imps. Next board:

Board 8
Neither side vulnerable

♠ A 7 6 2  ♥ A 10  ♦ A J 7 2  ♣ J 7 4

LHO opens with one club, partner passes, and RHO bids one heart. I prefer to have at least nine cards in my suits for a two-suited take-out double. But it's now or never. If I pass, I'm probably out of the auction for good. And what fun is that? I double.

LHO redoubles to show three-card heart support, and partner bids one spade. This bid does not necessarily show four spades. Partner must bid one spade any time he doesn't want to hear me bid two diamonds if he passes. So he could easily have only three spades.

RHO bids two hearts. I now know they have an eight-card heart fit, and so does partner. If two hearts is passed around to him, he should compete to two spades on almost any hand with four spades. Since I have no game interest and no fifth spade, there is no reason for me to bid two spades in front of him.

No reason opposite a reliable partner, that is. The robots are not always Law-abiding citizens, so there is a serious danger we will defend two hearts if I pass. I bid two spades. Even if partner has only three, maybe this won't be too bad. Or maybe we'll push them up a level.

LHO passes, and partner bids three diamonds. I was trying to push the opponents up a level, partner. Not us. Presumably partner is making a game try. Or maybe he's getting even with me for bidding his hand for him. Anyway, I'm below minimum for my auction, so I sign off in three spades. Everyone passes, and RHO leads the three of diamonds.

	NORTH Phillip ♠ A 7 6 2 ♥ A 10 ♦ A J 7 2 ♣ J 7 4

West chose to lead our second suit in preference to his partner's suit or the suit they bid and raised. So this is probably a singleton. The robots open one diamond with four-four in the minors, so the only way this can be a singleton is if East is 1-3-4-5. But how can that be? With four trumps, West wouldn't be going for ruffs. He would be leading one of their suits to start a tap. I've changed my mind. I suspect West is leading from length, trying to give his partner a ruff rather than going after one himself. In any event, I don't think he would lead from the diamond king. Maybe he has four small and the king is singleton offside.

I hop with the ace of diamonds. East plays the eight. No stiff king. The fact that East played the eight, however, is convenient. It means if I'm wrong about the diamond suit and West did lead from king-ten fourth, I haven't saddled myself with two diamonds losers. I can lead the queen to drive his king, then lead low to the seven, finessing against his ten.

I don't think that's the case, however. I suspect West led from three small, hoping his partner had a singleton and that the defense has a trump entry. Catching his partner with king doubleton as he did may be just as good. If I take a trump finesse and it loses, East can cash the king and put his partner in with a club for a ruff. 

I'm off three top tricks in the minors. I can afford to lose a spade trick so long as I don't lose a diamond ruff as well. Should I play ace and a spade in an attempt to stop the ruff? If East has king third of spades, that does no good. He still gets his ruff. Ace and a spade stops the ruff only if East has king doubleton. If West has king doubleton, ace and a spade lets East get a ruff he wasn't entitled to. 

Which layout is more likely? If East has king doubleton of spades, he holds six clubs. If West has king doubleton of spades, East holds five clubs. The latter is more likely. In addition, choosing to go after a diamond ruff in the first place is a more attractive defense if West holds a potential trump entry. So the diamond lead itself suggests West has the spade king. It looks right to finesse the spade.

I lead the ten of hearts from dummy. East covers with the jack. I play the king, and West follows with the deuce. I lead the spade queen, and West covers with the king. I win in dummy with the ace and play a low spade. East follows with the ten, so I have no further problems. I win, draw the last trump, and drive the diamond king. The defense cashes two clubs and I claim. 

Making four. I guess I should have accepted partner's game try.

	NORTH Phillip ♠ A 7 6 2 ♥ A 10 ♦ A J 7 2 ♣ J 7 4
WEST Robot ♠ K 8 5 ♥ Q 9 5 3 2 ♦ 10 4 3 ♣ Q 3		EAST Robot ♠ 10 4 ♥ J 8 6 ♦ K 8 ♣ A K 9 6 5 2
	SOUTH Robot ♠ Q J 9 3 ♥ K 7 4 ♦ Q 9 6 5 ♣ 10 8

The right play in the spade suit is trickier if queen-jack-nine are in dummy where the defense can see it. Suppose this is the layout and our goal is to take four tricks:

	NORTH ♠ Q J 9 3
	SOUTH ♠ A 7 6 2

The only four-one break where we can take four tricks is if East has the stiff king. We aren't going to play for that, so let's ignore four-one breaks.

There are seven cases where our play matters. East can hold king-ten (1 case), king-small (3 cases), or king-third (3 cases). We have four possible strategies. If we lead the queen and it holds, we can continue with a low card or we can continue with the jack. If the queen is covered and we win the ace, we can hook the nine on the way back or rise with jack, playing to drop the ten. Our four strategies are the four combinations of these decisions, which we will call Low-Hook, Low-Rise, Jack-Hook, and Jack-Rise.

What strategies does East have? He must cover the queen with king-ten, and he must duck with king-third. If he doesn't, we have no losing options. So his only choice is whether to cover or play low when he holds king-small. 

First, we'll figure out our best strategy the long way. Then we'll discuss a shortcut that leads to the same conclusion.

Since we don't know what East will do with king-small, we'll consider each of his strategies separately. The table below shows the number of cases where each of our strategies succeeds if East covers.

	Low- Hook	Low- Rise	Jack- Hook	Jack- Rise
K 10	0	1	0	1
K x	3	0	3	0
K x x	0	0	3	3
Total	3	1	6	4

As we can see, if East covers with king-small, our best strategy is Jack-Hook, that is, continue with the jack if East doesn't cover and finesse the nine on the way back if he does. This wins six times out of seven.

The next table shows the number of cases where each strategy succeeds if East ducks with king-small.

	Low- Hook	Low- Rise	Jack- Hook	Jack- Rise
K 10	0	1	0	1
K x	3	3	0	0
K x x	0	0	3	3
Total	3	4	3	4

If East ducks, the winning strategy is to rise with the jack if East covers (no surprise, since he covers only when holding king-ten). It's a toss-up what to do if he ducks.

Overall, our best strategy is Jack-Rise: If the queen holds, lead the jack. If it's covered, take the ace and lead to the jack. This guarantees four wins out of seven. Since East has available a strategy that holds us to four wins out of seven perforce, we can't do better than that. Jack-Rise ensures that we do as well as we are entitled to.

What's the best strategy for East? If South plays correctly, what East does with king-small makes no difference. His play matters only if South adopts one of the inferior strategies. Since East doesn't know which inferior strategy South will adopt, he can hedge his bet by adopting a mixed strategy. If the covers with king-small one sixth of the time, the payoff matrix is as follows:

	Low- Hook	Low- Rise	Jack- Hook	Jack- Rise
K 10	0	1	0	1
K x	3	2.5	.5	0
K x x	0	0	3	3
Total	3	3.5	3.5	4

Covering one sixth of the time ensures a South who misplays can't do better than three and a half wins out of seven whichever mistake he makes.

I promised you a shortcut. Since this theme occurs in a variety of suit combinations, a shortcut is useful. Here is a quicker way to come up with the best strategy:

There are seven cases we are concerned with. There is no strategy that is guaranteed to pick up both king-small and king-third. So the best we can possibly do is to pick up four cases: one of the major combinations plus king-ten. If we pick up king-ten, then we can't guarantee picking up king-small. So we give up on king-small. We resign ourselves to losing a trick to king-small no matter how East defends. We don’t play mind games and try to guess what East will do. We simply play to ensure we never lose a trick when East has king-third or king-ten. That way, we always win in four cases out of seven.

We stipulated earlier that our goal was to take four tricks. What if our goal is to take maximum tricks? We would like to take four tricks as often as possible, but not at the risk of losing two unnecessarily. So we can no longer ignore four-one breaks. Specifically, we must worry about king-ten fourth offside. If we lead the queen and it holds, then we continue with the jack and East shows out, we won’t be happy. 

Let’s add that layout to our list. Now we have ten cases to consider: King-ten onside (1 case), king-small onside (3 cases), king-third onside (3 cases), and king-ten fourth offside (3 cases). For the first three scenarios, a "win" consists of taking all four tricks. For the fourth scenario, a "win" consists of losing only one trick. We could add a row to our tables above, but let's use our shortcut instead.

Our goal is to find a strategy that wins in two of the three major cases. If it happens to win for king-ten doubleton, great. If not, six wins out of ten is the best we can do.

We know that no strategy wins for both king-small and king-third onside. So if there is a strategy that wins in two major cases, it must include king-ten fourth offside. The strategy that meets our criterion is Low-Hook. It wins against both king-ten fourth offside and against king-small onside. So, if our goal is to take maximum tricks, we continue low if the queen holds and hook against the ten if it's covered, winning in six cases out of ten.

Now see what Jazlene does on this board at JazPlaysBridge. Be sure to watch until 21:34. Don't stop when Board 9 shows up, since Jazlene circles back to Board 8 for some afterthoughts.

Challenge Match - Jazlene vs. Phillip - Board 7

No surprises on Board 6. I'm still trailing by seven imps.

Board 7
Both sides vulnerable

♠ A 7 6 4 3  ♥ K J 6  ♦ 3  ♣ K Q 9 4

I open with one spade in first seat. LHO overcalls with two diamonds. Partner passes, and RHO bids two spades, showing at least a limit raise in support of diamonds.

We discussed doubles of artificial bids back on Board 2, so you know I think double here should be take-out of diamonds. With a singleton diamond and support for the other suits, I should act. And a double of two spades, which partner can pass if he has nothing, is the safest way to get back into the auction. Passing, then making a balancing double of three diamonds is considerably more dangerous. Unfortunately, the robots play this double shows rebiddable spades, so I have to pass.

LHO bids three diamonds--pass--pass back to me. This is why I wanted to double two spades for take-out. It could easily be right to compete. But forcing partner to act at the three-level when both opponents have shown good hands is too dangerous. I have no choice but to sell to three diamonds. Fortunately, Jazlene and I are forced to play the same methods, so I'm not at a disadvantage as I would be in a normal field.

Partner leads the king of spades, and the following dummy appears:

	NORTH Robot ♠ Q J 9 2 ♥ Q 3 2 ♦ Q 10 2 ♣ A 10 6
		EAST Phillip ♠ A 7 6 4 3 ♥ K J 6 ♦ 3 ♣ K Q 9 4

(All pass)

Declarer plays the spade jack from dummy. Sure. Why not? He has the ten in his hand.

My agreement in a regular partnership is that discouraging suggests a heart shift. (When dummy's side suits are of equal length, discouraging suggests the suit with fewer honors. Clubs has two honors; hearts has one.) If I encourage, I'm saying I don't want a heart shift. Partner must use his judgment in deciding whether continuing spades or shifting to a club makes more sense. On this hand, I think he would decide to shift to a club, which is the suit I prefer. So I would play an encouraging seven.

Note there is no need to play suit preference here, as I'm sure some would. If you have well-defined rules for which suit a discouraging signal calls for, attitude works just fine. If you want the obvious shift (defined here as hearts), then you play low. You don't have to stop and ask yourself whether this is an attitude situation (where low asks for a heart shift) or a suit preference situation (where high asks for a heart shift). If you want the non-obvious shift, you encourage. If it's so clear that continuing the led suit makes no sense, partner will make the right shift, since he knows you don't want the obvious one.

There is nothing to gain by playing attitude sometimes and suit preference at other times, so why risk confusion? Even if it's clear this time which signal applies, there will always be borderline cases where you and partner won't agree. So why switch ever? If your card is always attitude, you can't have an accident.

Robots, however, play neither attitude nor suit preference, so it makes no difference which card I play. I choose the three.

Declarer plays the five, and partner continues with the spade eight. I wonder if declarer played the spade jack at trick one as a clever ploy to make West think I hold ace-ten over dummy's queen. Robots don't draw inferences, so partner won't realize I can't possibly hold the ten. Who better than another robot to understand that? I'll have to remember that trick.

Dummy plays the deuce. I win with the ace, and declarer plays the ten.

In bridge, as in many games, there are two general strategies of defense: Containment and Attack. The goal of Containment is to deprive declarer of tricks. The goal of an Attack is to take tricks ourselves before declarer can take his. The fundamental task of defense is deciding which strategy is better on a given deal. The reason for making this distinction is that we analyze differently depending on which strategy we adopt. For Containment, we focus on declarer's tricks. For Attack, we focus on our tricks.

On this deal, it may be easier to count declarer's tricks than ours, so let's start with Containment. What high cards does declarer have? It's hard to see his having less than ace, ace-king in the red suits for his two-level overcall. And if he's missing one of those cards, we might beat him whatever we do. So let's assume he has them.

What's his shape? If he has six diamonds, then he has eight top tricks (six diamonds and two aces), and we can't possibly stop him from eventually taking a spade trick. So we need to assume he has only five diamonds.

Ace-king fifth of diamonds and the heart ace gives him four or five diamond tricks (depending on who has the jack), the heart ace, the club ace, and two spades: eight or nine tricks in all. If we return a spade for partner to ruff, we eliminate one of his spade tricks, reducing him to eight tricks. (The diamond jack now becomes irrelevant. After partner ruffs, declarer will always have five diamond tricks.) Can declarer find a ninth trick somewhere? If he has the heart ten, he can. If not, I don't see where a ninth trick is coming from.

The next step is to double-check our plan by constructing a concrete layout. Sometimes an abstract plan has a flaw that is difficult to see unless you play through it. Let's give declarer

♠ 10 x  ♥ A x x  ♦ A K x x x  ♣ x x x

If we return a spade, declarer will pitch a club as partner ruffs. Partner will then shift to a club. Declarer will win his ace, draw trump ending in dummy, and pitch his last club on the fourth spade. If one of those heart x's is the 10, he can develop a heart trick and make his contract. If not, he's down. Yes, our analysis seems correct. 

We now have a provisional plan. The next step is to try to improve on it. Can we defeat the contract if declarer has the heart ten?

Perhaps an Attack will do better. A successful Attack requires us to establish and cash five tricks. If partner has the club jack and declarer has three clubs, we can shift to the club king and establish two club tricks. That gives us two spades, a heart, and two clubs. Again, we need to test our plan against a concrete layout. Let's add the heart ten to declarer's hand above so that the spade return will fail:

♠ 10 x  ♥ A 10 x  ♦ A K x x x  ♣ x x x

We shift to the club king. Declarer wins and draws trump, ending in dummy. They don't split, so he can't take his spade pitches. He must lose two clubs and a heart. Possibly a diamond as well if partner has the jack.

So Containment (returning a spade) works if partner has the heart ten, and Attack (shifting to the club king) works if partner has the club jack and declarer has three clubs. Since Attack requires two assumptions instead of one, Containment is more likely to be right.

Or so it appears at first glance. Let's confirm we're right about declarer's needing three clubs for the club shift to work. Give declarer:

♠ 10 x  ♥ A 10 x x  ♦ A K x x x  ♣ x x

If we shift to the club king, his best play is to win and cash a spade, pitching his club loser and letting partner ruff. This won't hurt if diamonds split, but it saves a trick (compressing his diamond and club losers) if partner has jack fourth. Partner will now try to cash a club. Declarer will ruff, draw trump ending in dummy, pitch a heart on the last spade, then play a heart toward his ten. We get only four tricks: two spades, a heart, and a ruff.

Yes, a club shift fails if declarer has a doubleton club. What about our assumption that partner needs the club jack? If declarer has jack third of clubs, we can take only one club trick. But maybe that's enough. If partner has jack fourth of diamonds, perhaps we can take two spades, one club, one heart, and a diamond.

Let's check it out. Give declarer

♠ 10 x  ♥ A 10 x  ♦ A K x x x  ♣ J x x

We already know a spade continuation fails on that layout. What happens if we shift to the club king? Declarer wins in dummy and leads a second club. If we hop, declarer unblocks his jack. We continue with a club to dummy's ten to kill the entry. Now what? Declarer cashes a spade, pitching one heart as partner ruffs, then draws trump ending in dummy to pitch his last heart. We get our club trick, but we don't get a heart trick.

Perhaps, instead of hopping with the club queen, we should duck and let declarer win his jack. This deprives him of using the club ten as a dummy entry. If we do that, declarer can continue with a third club. We win and find ourselves in this position:

	NORTH Robot ♠ Q 9 ♥ Q 3 2 ♦ Q 10 2 ♣ --
WEST Robot ♠ -- ♥ x x x x ♦ J x x x ♣ --		EAST Phillip ♠ A 6 4 ♥ K J 6 ♦ 3 ♣ 9
	SOUTH Robot ♠ -- ♥ A 10 x ♦ A K x x x ♣ --

We're endplayed. A heart or a club shift gives declarer a trick, taking care of one of his small hearts. He can then cash a spade, pitching his last heart as partner ruffs. He loses only four tricks: two spades, one club, and a ruff. Our only safe return is a diamond, and that gives declarer two dummy entries. Declarer can now pitch one heart on a spade as partner ruffs, and eventually pitch his last heart, again losing two spades, a club, and a ruff.

Yes, a club return does indeed require finding partner with the jack and finding declarer with three clubs while a spade continuation requires only finding partner with the heart ten. So a spade continuation is the better play.

I return a spade. Declarer pitches the three of clubs, and partner ruffs with the nine of diamonds. Partner shifts to the eight of hearts.

Hearts? Why are we breaking hearts, partner? Oh, I see. He's hoping I have the ace, so I can play another spade and kill that trick as well. Let's hope the shift is from ten-eight-seven. If so, we still have a heart trick coming.

Declarer plays the deuce from dummy, and my jack forces his ace. Declarer draws three rounds of trump, ending in his hand, and leads the nine of hearts--ten--queen--king. I return the six of hearts. Partner overtakes with the seven. Down one.

	NORTH Robot ♠ Q J 9 2 ♥ Q 3 2 ♦ Q 10 2 ♣ A 10 6
WEST Robot ♠ K 8 ♥ 10 8 7 4 ♦ J 9 6 4 ♣ J 7 2		EAST Phillip ♠ A 7 6 4 3 ♥ K J 6 ♦ 3 ♣ K Q 9 4
	SOUTH Robot ♠ 10 5 ♥ A 9 5 ♦ A K 8 7 5 ♣ 8 5 3

Partner had both the heart ten and the club jack, so either Containment or Attack would have worked.

Jazlene and I don't agree on this one. She initially played as I did but later decided later that a club shift was better. Watch her play on Jaz Plays Bridge, then watch her post mortem.

Challenge Match - Jazlene vs. Phillip - Board 6

Board five was a push, so I'm still down seven imps.

Board 6
Opponents vulnerable

♠ J 7  ♥ K Q J 6 4 3  ♦ K 2  ♣ K Q 10

Six heart tricks, half a trick in diamonds, a trick and a half in clubs. Seven in all, not quite good enough to open with one heart and rebid three hearts.

I bid heart, LHO overcalls with two diamonds, partner passes, and RHO bids two notrump. I have a pretty good hand, but partner couldn't act over two diamonds, and RHO's two notrump suggests hearts may not be breaking. So I pass, as does everyone else.

What should I lead against two notrump? Should I try a heroic low heart in case declarer has ace-nine fourth and partner has the ten? LHO might have removed two notrump if he had a stiff heart, so if declarer does have four hearts, partner probably has a singleton. Hoping it's a stiff ten is a bit much. I'm better off hoping declarer has only three hearts. But at least, if a low heart lead turns out to be right, I can say I thought about it.

I lead the king of hearts and see the following dummy:

	NORTH Robot ♠ A 4 ♥ 10 7 ♦ A Q 9 8 5 4 ♣ 7 6 3
WEST Phillip ♠ J 7 ♥ K Q J 6 4 3 ♦ K 2 ♣ K Q 10

West	North	East	South
Phillip	Robot	Robot	Robot
			Pass
1 ♥	2 ♦	Pass	2 NT
(All pass)

Declarer plays a curious ten of hearts from dummy. Partner plays the eight; declarer the six.

If diamonds are running, we aren't beating this. Can we beat it if partner has jack third of diamonds? Declarer then has five diamonds and two aces. The tooltip says two notrump show 11 HCP. There are 15 HCP missing, so even if declarer has stretched a point, partner has at most five. That means he can't have both the club ace and the spade king. Declarer must have one of those cards, so he has eight tricks even after losing a diamond.

One possibility is to switch to clubs, playing partner for ace fourth. But if he has that, we can always cash clubs when partner wins his diamond trick.

What if partner has jack fifth of clubs? In that case, I must switch to clubs now to knock out the ace, giving us a heart, four clubs, and a diamond. Is that possible? That gives declarer a 6-3-2-2 shape. I don't think so. My best shot is to continue establishing hearts and hope partner has jack-ten fourth of diamonds, so that the diamond suit isn't a threat. 

I continue with the queen of hearts. Oops. That was a mistake. I'm supposed to lead the jack, since I want a club return when partner wins his diamond. Good thing partner pays no attention to my signals. Partner follows with the deuce of hearts and declarer wins with the ace.

Declarer plays the three of diamonds--deuce--nine--ten. Declarer can't have a stiff diamond. If he did, he would be finessing the queen, not the nine. So dummy's diamonds are now good. 

Partner shifts to the deuce of clubs, and declarer takes the ace. This is the position:

	NORTH Robot ♠ A 4 ♥ -- ♦ A Q 8 5 4 ♣ 7 3
WEST Phillip ♠ J 7 ♥ J 6 4 3 ♦ K ♣ K Q

We're not beating this. So it's all about stopping overtricks now. After declarer runs the diamonds, I'm left with four cards. What should they be? If declarer has king-ten of spades, I must keep both spades, else declarer can cash the ace and finesse against partner's queen. So my last four cards will be

♠ J 7  ♥ J  ♦ --  ♣ K.

Actually that might not work. If declarer holds jack doubleton of clubs in the end position, he can duck out my king. I can't decide what to hold until I see what declarer keeps. If he holds three spades, I have to keep both spades. If he holds two clubs, I must keep both clubs. If he holds a heart, I must keep the heart jack. If I'll have to pay attention. And here I was hoping to catch a nap. Oh, well.

Declarer has played the club ace. I follow with the ten. (In real life, this card would be face down on the table and I would now turn it over. That's how a defender can pause play to give himself time to absorb what's happened without misleading declarer into believing he is thinking about the current trick. Those who designed online play forgot about this option. There should be a "play card face down" button.)

Declarer plays a diamond to the ace and cashes the queen. Partner plays six-jack in diamonds; declarer pitches the four of club; I pitch the three of hearts.

On the next diamond, partner pitches the deuce of spades. The robots almost always discard count cards, so partner is presumably 5-2-3-3 and declarer is 4-3-2-4. Declarer pitches the nine of hearts. If my construction is correct, declarer is down to four spades and three clubs. I pitch the heart four. Since declarer is out of hearts, I can now throw all my hearts if necessary. 

On the next diamond, partner pitches the spade three; declarer, the spade eight. Declarer still has three spades left, so I can't pitch a spade yet. I pitch another heart. On the last diamond, partner pitches the five of spades; declarer, the ten of spades. Declarer is down to two spades and two clubs. I can afford a spade now, so I pitch the spade seven. We are down to this position, with dummy to play:

	NORTH Robot ♠ A 4 ♥ -- ♦ -- ♣ 7 3
WEST Phillip ♠ J ♥ J ♦ -- ♣ K Q		EAST Robot ♠ ? ? ♥ -- ♦ -- ♣ x x
	SOUTH Robot ♠ ? ? ♥ -- ♦ -- ♣ x x

Declarer leads the three of clubs from dummy. What's he doing? Why not cash the spade ace? Is he trying to endplay me? Maybe he thinks I'm now down to

♠ K x  ♥ J  ♦ --  ♣ K.

If declarer is trying to endplay me, he must have the queen of spades. So this is the position:

	NORTH Robot ♠ A 4 ♥ -- ♦ -- ♣ 7 3
WEST Phillip ♠ J ♥ J ♦ -- ♣ K Q		EAST Robot ♠ K x ♥ -- ♦ -- ♣ x x
	SOUTH Robot ♠ Q x ♥ -- ♦ -- ♣ x x

The right defense is for me to win with the king of clubs and cash my heart. Partner must stiff his spade king and hold onto a club. Now if I lead the spade jack, declarer might get greedy, duck it, and go down.

Playing with a partner I trusted, that's exactly how I would defend. Partner can see that stiffing his spade king is our only chance to beat this, so he should go for it. But robots aren't that tough. If I win the club and cash a heart, partner is going to come down to a doubleton king of spades like a wimp.

What if I win the club king and lead the jack of spades immediately, without cashing my heart? Declarer might still duck and go down. This line is a lot less convincing than letting partner stiff his king. But playing with a robot, it's the best I can do.

Partner follows to dummy's club lead with the five, and declarer plays the jack. I win with the king and play the jack of spades.

Declarer doesn't bite. He hops with the ace. Making two.

	NORTH Robot ♠ A 4 ♥ 10 7 ♦ A Q 9 8 5 4 ♣ 7 6 3
WEST Phillip ♠ J 7 ♥ K Q J 6 4 3 ♦ K 2 ♣ K Q 10		EAST Robot ♠ K 6 5 3 2 ♥ 8 2 ♦ J 10 6 ♣ 8 5 2
	SOUTH Robot ♠ Q 10 9 8 ♥ A 9 5 ♦ 7 3 ♣ A J 9 4

Maybe I was too quick to go into stop-the-overtrick mode. We still had a chance to beat it that I didn't see. My goal should be to represent

♠ K J 7  ♥ K Q J 6 4 3  ♦ K 2  ♣ K 10

and entice declarer into endplaying me. 

How would I discard if that were my hand? I would probably pitch a spade early, so that's what I should do. If I pitch a spade at my first opportunity, a good declarer would be disinclined to think I had stiffed my jack. So in the end position, he would "know" I had king-jack of spades left and might well go for the endplay. And my lucky mistake of giving the wrong suit-preference signal at trick two would reinforce that illusion. (I would, of course, tell declarer I was thinking ahead and had falsecarded with the heart queen on purpose.)

Would declarer really risk his contract for an overtrick at IMPs? He should if he thinks the odds are good enough. Yes, you are risking six imps to gain one. But if you think it's ten to one you've read the position correctly, going for the overtrick is the percentage play. Why throw that 0.36 imps away?

What if you're wrong and go down? Then you have to be philosophical about it. I once lost a Spingold match by two imps. After we compared, my teammate told me that, on the last board, he had gone down in one notrump by playing for a "sure" overtrick. When he showed me what had happened, I couldn't blame him. He had made the right play. On a different day, that overtrick might have swung the match in our favor, and I would be congratulating him on his thoughtful play. So I could hardly take issue now. Besides, it was Edgar Kaplan. I would assume he had done the right thing even without seeing the deal.

Be sure to go to Jaz Plays Bridge and see what Jazlene does on Board 6. Let's hope she doesn't bid a fearless three hearts over two notrump and pick up a couple of imps.

Challenge Match - Jazlene vs. Phillip - Board 5

Board 5
Our side vulnerable

♠ A K 10  ♥ K 8  ♦ A 10 9 8  ♣ K 9 8 7

Two passes to me.

Despite holding only 17 HCP, this hand is too good to open with a strong notrump. My HCP are all in aces and kings, and I hold two tens and no card lower than a seven. K&R point count evaluates the hand as 18.9 points. 

Still, I've never had much success opening one of a minor instead of one notrump with hands that the Work point count undervalues. Yes, sometimes you reach game or slam that you would miss after a one notrump opening. But that's aiming for a narrow target. More often, it seems, you get a poor result by letting the opponents in at the one-level, especially at this vulnerability. Since partner is a passed hand, at least I don't have to worry about missing a slam. So I decide to make the tactical underbid of one notrump and hold my breath.

LHO passes, and partner bids four hearts, a transfer to spades. I can let my breath out now. I bid four spades, and everyone passes. LHO leads the deuce of diamonds.

	NORTH Robot ♠ Q 9 8 7 3 2 ♥ A 7 ♦ Q 5 4 3 ♣ J

(All pass)

If the lead is from jack third or fourth, I'm taking four diamond tricks. But the robots don't like leading from honors, so it's likely the lead is a singleton. I play low from dummy, East plays the jack, and I take my ace.

I can pick up four-zero trumps in either hand if I cash the ace first, so I cash it. West plays the five; East, the six. I continue with the spade king and both opponents follow. West held the jack.

It looks as if I'm losing the diamond king and the club ace to make five. If East has the ace of clubs, is there any way to convince him to duck when I lead the club jack from dummy? Maybe. If East thinks I'm missing the heart king, then dummy's heart is a loser. If he hops with the club ace and I have the club king, then the heart loser goes away. So he might duck, hoping I have king-ten and misguess.

At least a human East might. Robots never play for a misguess; they assume you're double dummy. But even if I'm double dummy, it could be right to duck. Say I have queen-ten of clubs. Then hopping allows me to take a ruffing finesse against West and pitch my heart loser.

This means if I want to make it dangerous for East to hop, I must keep the heart ace in dummy. If I lead a heart to the ace and play a club, he has no reason to duck. He can simply hop with the ace and play a heart.

So leading a heart to dummy can't possibly work. What about a spade? The problem with leading a spade to dummy is I now have no fast entry to my hand. If East is worried about losing a heart trick, he can hop with the club ace and shift to a heart. I can't get to my hand in time to take my putative pitch. 

Leading a heart to dummy doesn't work. Leading a spade to dummy is better, since it requires a tad more care on East's part. But it probably won't work either. A diamond is the only option left. Let's give it a try.

I play the eight of diamonds. West pitches the six of hearts, and I play low from dummy. East takes his diamond king and returns the diamond seven. Yes! Perfect! I overtake in dummy with the queen as West pitches the four of clubs. We've reaching the position I was aiming for:

	NORTH Robot ♠ Q 9 8 7 ♥ A 7 ♦ 5 ♣ J
	SOUTH Phillip ♠ 10 ♥ K 8 ♦ 10 ♣ K 9 8 7

Now when I lead the jack of clubs, East has a legitimate reason to duck. If I have queen-ten of clubs and no heart king, he must duck to stop the second overtrick.

I lead the club jack. East hops with the ace. Oh, well. I claim the balance. Making five.

	NORTH Robot ♠ Q 9 8 7 3 2 ♥ A 7 ♦ Q 5 4 3 ♣ J
WEST Robot ♠ J 5 ♥ Q J 10 6 5 4 ♦ 2 ♣ 6 4 3 2		EAST Robot ♠ 6 4 ♥ 9 3 2 ♦ K J 7 6 ♣ A Q 10 5
	SOUTH Phillip ♠ A K 10 ♥ K 8 ♦ A 10 9 8 ♣ K 9 8 7

East had ace-queen of clubs, so he had no temptation to duck. Still, I don't understand his diamond return after winning the king. Couldn't I have the same hand with the queen of hearts instead of the king, in which case he must shift to a heart?

The only reason I can think of to play a diamond is he thought I had forgotten to draw the last trump and his partner was ruffing. A priori, playing for the ruff is probably percentage. But I can't have that hand. Until we teach robots to draw inferences, their card play is never going to get above a beginner level.

My one notrump opening did keep the opponents out of the auction, although it probably didn't matter. I'm not sure why West didn't bid anyway. Though perhaps there isn't much point playing Cappelletti, where you announce to partner that you have a suit to bid but you aren't going to tell him which one. I would certainly overcall one notrump with two hearts if it were natural.

While my swindle didn't work, this hand is an excellent example of the necessity of looking at a deal through your opponent's eyes. Sneaking a club through has a better chance to work if you sit in your opponent's seat and imagine a scenario where ducking makes sense. 

This has become my favorite type of play problem. When I was a beginner, my favorite hands were winkles. But any fool can execute a winkle. Even a robot. Seeing a deal through your opponent's eyes is hard. And fun. And often more profitable than it was on this deal.

Now take a look at the deal from Jazlene's eyes at Jaz Plays Bridge. I suspect the board is a push and she's still up seven imps. We'll see.

Challenge Match - Jazlene vs. Phillip - Board 4

My match against Jazlene Ong continues. Board three was another push, so I'm still up the five imps I gained on board one. Now on to

Board 4
Both sides vulnerable

♠ A Q  ♥ A K Q 5 4 2  ♦ A 10  ♣ Q 4 2

LHO and partner pass, and RHO opens with three spades.

My choices are four hearts and three notrump. If they lead a spade and hearts break, I have nine tricks in notrump. If they don't lead a spade, maybe dummy will have an entry in hearts. In any event, nine tricks rates to be easy in notrump. I might not have a tenth trick in hearts.

I know some would double with this hand, considering it too good for either three notrump or four hearts. Whether double makes sense or not depends on how you play this auction:

You	LHO	Partner	RHO
			3 ♠
Double	Pass	4 ♣/♦	Pass
4 ♥

If this auction shows a strong hand with an independent heart suit--a hand too good to overcall with four hearts, then double is the right call. But I don't believe that's what it should show. On the contrary, I believe this auction should deny an independent heart suit. It shows doubt about strain, not doubt about level. Typical hands would be:

♠ x x  ♥ A K x x x  ♦ A x x  ♣ A K x

or

♠ x x  ♥ A J 10 x x  ♦ A x  ♣ A K Q x

Obviously those of us who double and bid four hearts with these hands don't expect partner to pass four hearts with a bad hand and a singleton heart. Those who double with the hand I'm currently holding presumably do.

You can agree to play either way. But if you don't play that double shows doubt about strain, I think you are making a serious mistake. With an independent suit, there is always something you can bid, namely, your suit. While you may have to guess how high to bid it, you're never stuck for a bid. But what exactly are you supposed to do with my example hands if you can't double and follow with four hearts? You have no sensible call with a hand type that's quite common.

I'm not sure how the robots play. But I can't get into too much trouble if I bid three notrump, so that's what I do. LHO bids four spades, and partner doubles.

If partner has a little something, I can probably manage ten tricks in notrump. So at matchpoints, I would consider bidding four notrump. At IMPs that doesn't make much sense. It's unlikely we're beating four spades less than two, so if I pull to four notrump, I'm trying for a measly four-imp pickup. And the downside is huge. If they can run clubs or if hearts don't break and four notrump goes down, I'm losing 12 imps. Those aren't good odds. There is no vig in pulling a double to a game at IMPs when you can collect a game bonus by passing.

Pulling the double to six hearts, however, is another matter. Now at least I have some upside. What do I need for slam to be cold? King of diamonds, king of clubs isn't quite enough. I need the club jack or the queen of diamonds in addition. Even king of diamonds, ace of clubs isn't enough. I still need a slow trick in one of the minors. I also have no guarantee that hearts are solid, although partner's presumed spade singleton increases the odds that they are. Finally, there is the possibility that the defense can start with ace of clubs and a ruff.

In short, there are three ways bidding slam can be wrong: Partner has the wrong cards, hearts don't break, or the defense gets a ruff. While any one of those chances may be small, they add up. And, because of the pre-empt, bad breaks are more likely than they would be a priori. It's close. Add the jack of clubs to my hand and I would certainly bid six hearts. But with this hand I decide to defend.

I pass, LHO passes, and I lead the king of hearts.

Partner plays the three and declarer follows with the seven. I don't see any reason not to try to cash another heart. But before I do, I must decide what I'm going to do if declarer ruffs and plays a low diamond. If I intend to duck, I need to do so in tempo. I know my robot declarer won't pay any attention to my tempo, but it's good practice to pretend I'm playing against a human. Should I duck or not?

Hopping saves a trick if declarer is 7-1-1-4. But ducking won't cost the contract, and declarer is more likely to have a doubleton diamond than a singleton. So I intend to duck.

I continue with the queen of hearts. Partner plays the jack, and declarer ruffs with the spade three. One of these days, I'll figure out how to formulate a rule that partner's play on this trick is surrogate count--that is, count in diamonds--so I'll know for sure whether to duck or not. It's clearly the most important piece of information for me. But I'm not sure how to make an unambiguous rule for when it applies.

Declarer doesn't play a diamond, however. He leads the king of spades. That suggests declarer does have a singleton diamond. If he had a doubleton, why not try to reach dummy to finesse against the spade queen?

I win with the ace of spades as partner follows with the deuce. I shift to the deuce of clubs. Partner takes the ace, and declarer follows with the six. Partner continues with the club jack, and declarer takes the king. We've reached this position with declarer on lead:

	NORTH Robot ♠ 9 4 ♥ -- ♦ K J 9 8 7 ♣ 7
WEST Phillip ♠ Q ♥ A 5 4 2 ♦ A 10 ♣ Q

Declarer continues with the eight of spades to my queen, and partner pitches the three of diamonds.

That card is count--even from a robot. And it should show five, making declarer 7-1-1-4 with a stiff deuce of diamonds. If partner has four diamonds, he must have a spot higher than the three, and he should play it.

I know, however, that the robots are fond of bloodless count. With four, he would pitch his next-to-lowest diamond. Some unenlightened humans do that, too. It makes no sense. If you're going to signal, signal loudly. Either play your lowest card or play the highest one you can afford. What do you have to gain by playing a card partner might be unable to read?

Since the robots stubbornly refuse to listen to me on this matter, partner could easily have four diamonds. So I'm on my own. If declarer is 7-1-2-3, I should cash my club queen and lead a low diamond, making declarer guess. If he guesses right, he's down three and we collect 800. If he guesses wrong, we collect 1100. If he's 7-1-1-4, however, I must cash the diamond ace. If I underlead, he will hop with the king and get out for 500.

If I underlead, how likely is he to get it right? I would certainly bid three notrump with the diamond queen instead of the ace. And partner's auction would be the same. So I see no reason declarer shouldn't guess wrong. On the other hand, as I noted at trick two, declarer's failure to try to get to dummy for a trump finesse suggests he has a singleton diamond rather than a doubleton.

Another consideration is the risk vs. the reward. The difference between 500 and 800 could be worth more imps than the difference between 800 and 1100. If Jazlene is in game at the other table, trading plus 800 for plus 500 converts a four-imp win into a four-imp loss, for a net loss of eight imps. Converting 800 to 1100 converts a four-imp win to a ten-imp win for a net gain of only six imps. You don't need to know the IMP table off the top of your head to reach this conclusion. It's sufficient to know that, the way the IMP table is constructed, converting a gain into a loss is costly. If that's a possibility, trying to convert a gain into a larger gain is generally not worth the risk.

I cash the ace of diamonds, settling for plus 800.

	NORTH Robot ♠ 9 7 4 ♥ 9 8 ♦ K J 9 8 7 ♣ 8 7 3
WEST Phillip ♠ A Q ♥ A K Q 5 4 2 ♦ A 10 ♣ Q 4 2		EAST Robot ♠ 2 ♥ J 10 6 3 ♦ Q 6 3 2 ♣ A J 10 5
	SOUTH Robot ♠ K J 10 8 6 5 3 ♥ 7 ♦ 5 4 ♣ K 9 6

Declarer did have a doubleton diamond. Who knows if he would have guessed right or not had I underled?

We're making six hearts. Partner didn't have much, and it's a fine contract, so perhaps I was too conservative in passing the double. To check, I did a simulation using DealMaster Pro. If I give partner 8-10 HCP and specify spades are three-seven, six hearts makes 74% of the time. I'm not surprised it's a favorite, but I wasn't expecting it to be that much of a favorite. I clearly made an error in passing the double. How long will it be before DealMaster Pro comes out with a version that can be installed in your head? DealMaster Pro 7.0 - for Windows, Mac, or cerebrum.

I also made an error in the play in forgetting that slam was a possibility at the other table. If Jazlene is in six hearts, the odds on underleading the diamond ace change dramatically.

If declarer is 7-1-1-4, then six hearts is going down. Collecting 500 instead of 800 means I win 12 imps instead of 14, so the underlead risks practically nothing. But if declarer is 7-1-2-3, six hearts is making. Now I'm losing 12 imps if I collect 800. But if I underlead and declarer misguesses, I hold my loss to eight imps. In short, I'm risking two imps for a chance to collect six. Clearly the odds favor the underlead.

Again, you don't need to memorize the IMP table to reach this conclusion. It suffices to know that converting a win to a larger win or converting a loss to a larger loss generally makes little difference. Your primary goal at IMPs is to beat the other result or, if you can't, to get as close to the other result as possible. Even without knowing the actual imps at stake, we know that getting closer to 1430 will gain more imps than moving away from 1430 will lose.

So how did I do? Will Jazlene bid slam and obliterate my five-imp lead? Check out Jaz Plays Bridge to find out.

	NORTH Robot ♠ J 3 ♥ A 10 5 3 ♦ K Q 10 ♣ K J 6 4

I play the jack from dummy, East covers with the queen, and I win with the king.

If the lead was from a doubleton ten, my nine is a stopper. But that would mean East passed over one heart with ace-queen sixth of spades. I suppose that's possible, since he is vul against not. It's also possible that West led the ten from ace-ten third. The ten is the normal lead from honor-ten third to start an unblock. Imagine, for example, I held the same hand without the spade nine. If West leads the ten from ace-ten third and I take the king, the defense can cash four spade tricks. If West leads low, he blocks the suit.

What do I need to do to make this? I have four diamond tricks, two hearts, and one spade. I need two more. I can develop two club tricks by knocking out the ace. If West wins the ace, they can't beat me. If East wins and plays a spade, I have to guess whether to duck, playing West for ace-ten third, or to hop, playing West for ten doubleton.

It's not much of a guess. A timid East might pass over one heart with ace-queen sixth of spades and out. But no one would pass with ace-queen sixth and an ace. Well, maybe Harold Berlin. But he's not around anymore. So if East shows up with the club ace, the spade ace is 100% to be on my left. 

Furthermore, even if East forgot to look at his hand during the bidding, he's probably looking at it now. If he holds ace-queen sixth of spades, for all he knows, his partner has led from ten-nine doubleton and the spades are running if he cashes them from the top. How could he ever underlead his ace and risk West's winning his stiff nine? So I have two reasons to duck a spade return. 

If I were actually worried about "misguessing" spades, I could play a diamond to dummy and a heart to my jack.  If I can take four heart tricks, I won't need to knock out the club ace. Losing the heart finesse to West won't hurt, since if he continues spades, he gives me my ninth trick. If he doesn't, I can just revert to playing on clubs. But I'm not getting the spades wrong. So why throw an imp away for no reason? 

Which club should I lead? Since dummy has the six, it makes no difference whether I lead the five or the seven. I choose the seven out of habit. West hops with the club ace and cashes the ace of spades, presumably hoping his partner has the nine and the suit is running.

I claim the rest. Making five.

	NORTH Robot ♠ J 3 ♥ A 10 5 3 ♦ K Q 10 ♣ K J 6 4
WEST Robot ♠ A 10 8 6 ♥ 4 2 ♦ 9 5 4 2 ♣ A 8 3		EAST Robot ♠ Q 7 5 2 ♥ Q 9 8 7 ♦ 7 6 ♣ 10 9 2
	SOUTH Phillip ♠ K 9 4 ♥ K J 6 ♦ A J 8 3 ♣ Q 7 5

West had ace-ten-eight fourth? That holding I wasn't expecting. In a real game, I would wonder if partner had flashed his hand and West had caught a glimpse of the jack. In that case, leading the ten might make some sense. It turns out I was wrong when I said it wouldn't hurt to lose a heart finesse to West. Since West holds four spades, I could go down if the finesse lost and East had the club ace.

I want to go back to a statement I made earlier. I said that it made no difference whether I led the club five or the seven, because dummy held the six. What if dummy held KJ43? Would my choice make a difference now?

It might. Suppose, for example, that the six is West's lowest card. If I lead the five and West follows the six, East will know West played low. But if I lead the seven, East won't know whether the six is low or the start of an echo with six-five. When dummy holds the six, however, the five and seven are equals, so it's impossible to introduce an ambiguity. On this particular deal, scrambling a count signal probably won't matter. But it's good to get in the habit of keeping the opponents in the dark when you can.

About fifteen years ago, I wrote a whole blog on the rules for declarer's spot-card plays, showing how to create the maximum ambiguity in a variety of situations. If you go back and read all the posts from the last fifteen years, I'm sure you'll find it. But before you do, head over to Jazlene's YouTube channel to get her comments on Board 3.

Speaker 2: OK.

Speaker 1: We're analyzing a match between these two players, Phillip and Jazlene, using their own commentary.

Speaker 2: Their own commentary. So they're both talking about the same match.

Speaker 1: Yeah. So Phillip has this blog called Gargoyle Chronicles.

Speaker 2: Gargoyle Chronicles, OK.

Speaker 1: Yeah. And he writes these really detailed posts about his bridge games.

Speaker 2: Interesting.

Speaker 1: And then we have Jazlene. She's more of a YouTube kind of gal.

Speaker 2: Ah! So she's got videos of her gameplay.

Speaker 1: Exactly. She's got this channel called Jazz Plays Bridge and she breaks down her matches, her thoughts, everything.

Speaker 2: That's awesome. So we get like a two-sided perspective on the same game.

Speaker 1: It's double the strategy, double the drama, and hopefully double the (ha ha) moments for us and the listener.

Speaker 2: I'm in. Let's do it.

Board 2
IMPs, Our side vulnerable

♠ A K Q 9  ♥ A J  ♦ J 9 3  ♣ K 10 8 6

I won five imps on Board 1. Let's see if I can hold on to my lead.

RHO passes. I open with one club, intending to rebid two notrump. The opponents have other ideas, however. West overcalls with one notrump and RHO bids two diamonds, a transfer to hearts.

What should a double by me mean? Many play a double of two diamonds as showing diamonds. Personally, I think double is more useful as take-out of hearts. Yes, I could pass, hoping to make a balancing double of two hearts. But doubling two diamonds for take-out is safer. If partner has some 3-4-3-3 Yarborough, he won't be pleased with a balancing double of two hearts, but he can pass two diamonds doubled and possibly stay out of trouble.

A good general rule is this: If we've opened the bidding, doubles of artificial bids are for take-out of the suit shown. If they've opened the bidding, the meaning of double depends on the strength shown by the artificial bid. If it shows at least game-invitational strength, double is lead-directing. If not, double is take-out of the suit shown. Here, two diamonds could be weak, so double should be take-out of hearts whether or not we've opened the bidding. 

A similar situation arises is when you open, LHO overcalls, and RHO cue-bids your suit to show support. Double to show a take-out of the overcalled suit makes more sense to me than doubling to "rebid" your suit.

A double of Drury, however, shows clubs. The opponents have opened the bidding and responder's two-clubs shows invitational values. So double is lead-directing. 

In any event, that's not how the robots play. They play double shows diamonds. So if I double, this hand will be a serious disappointment to partner.

I pass, and LHO bids two hearts, passed back to me. I have the heart shortness, so it's my job to compete. If partner has that 3-4-3-3 Yarborough, that's just too bad. I can't risk losing 6 imps when both two hearts and two spades are making.

I double, and partner bids three diamonds. After two passes, LHO competes to three hearts--pass--pass to me. We pushed them up a level. Let's see if we can beat them. I pass, and partner leads the eight of hearts.

Even with five diamonds, partner probably would have bid two spades with four of them to keep the auction a level lower. And with four-card support for my suit, partner would have bid three clubs rather than three diamonds. If we assume South has four hearts for his three-heart bid, partner rates to be 3-2-5-3, leaving declarer with 3-4-4-2. Although a six-card diamond suit for partner is also possible.

The robots aren't always Law-abiding citizens, though. Might South have competed to three hearts with three-card support? That would mean partner is 3-3-4-3, making declarer 3-3-5-2. No, I don't think so. With five diamonds South would surely choose to defend rather than bid three hearts. I'm sticking with my assumption that partner is 3-2-5-3 or has six diamonds and a black-suit doubleton

What about high cards? There are 17 HCP outstanding, so partner has at most a queen. Let's hope it's the club queen. Then we can take a heart, three spades, and a club for down one. If partner is 3-2-6-2, he doesn't need the club queen to beat it. Declarer then has an unavoidable club loser.

Declarer plays low from dummy. Hmm. I just had a wild thought. What if partner's 2 HCP is the heart queen? Then I must insert the jack to beat this. If I could cater to the possibility at no cost, I would. But I can't let declarer win the first trick and pitch a spade away on the diamond king. The fact that a low heart lead from queen doubleton even crossed my mind shows the effect of years of sitting across the table from Lowenthal. I win with the heart ace and declarer follows with the six.

Now to cash spades. With the jack of spades in dummy, my correct play is the queen, asking for count. The king would ask for attitude; the queen shows I have all the spade honors and would like to know how many are cashing. Not that it matters. Robots don't signal, and I'm playing three rounds of spades however partner cards. But I lead the queen anyway just for practice. 

Declarer plays the seven; partner, the deuce. I cash two more spades. Declarer plays three, seven; partner plays six, ten. After giving count, the six should be suit-preference. Partner doesn't necessarily have anything. But if he does, it should be the club queen.

But, again, robots don't signal. And it wouldn't matter if they did. I see no reason to do anything but exit passively and wait for a club trick.

I exit with the jack of hearts--seven--deuce--king. Declarer leads the deuce of clubs off dummy. It would be embarrassing to play low and let him insert the seven from ace-queen-seven. It's unlikely he would do that, but it can't hurt to play the eight, so I do. Declarer plays the queen. Unfortunately, declarer has ace-queen doubleton, so we have no more tricks. Making three.

I don't care for South's timid two-heart bid. I think almost any hand with four trumps is a pre-acceptance. And this is quite a good hand with four trumps: four probable winners outside the heart suit plus a ruffing value. Just make partner two-two instead of three-one in the pointed suits and you want to be in four hearts. Not that you're getting there even after a pre-acceptance. But it shows how close to game you are. North could easily have a bit more and not even dream of making a game try after a simple two heart bid.

I can just imagine defending this hand with Lowenthal. I win the heart ace at trick one and cash spades, starting with the queen. John plays the ten (we played upside-down count), then six-deuce. I now know he doesn't have the club queen, so I need to hope declarer has ace-queen-small of clubs and we have a club trick coming. But does that make sense? That gives John

♠ 10 6 2  ♥ x x ♦ Q x x x x x  ♣ x x.

With a doubleton in my suit, why lead a trump? Why not go after a club ruff? And if you lead a trump, why the eight? The right lead from a doubleton trump is low. That means John has either ten-eight or queen-eight. Maybe I should lead the thirteenth spade, so John can ruff with the queen for an uppercut, getting back the trick I blew at trick one. What's more likely, that John led a trump from the hand above or that he led a trump from

♠ 10 6 2  ♥ Q 8  ♦ x x x x x  ♣ x x x?

The answer may depend on whether he has a kibitzer. He likes to keep his kibitzers entertained.

I miss playing with John. He always kept you on your toes. Now stay on your toes and tiptoe over to Jazlene's YouTube channel to get her result and her perspective on Board 2.
