Match 2 - Board 52

Board 52
Both sides vulnerable

♠ J 6 9 4 2 K J 10 5 ♣ Q J 7 2

LHO opens one diamond, partner overcalls with one spade, and RHO makes a negative double. I bid one notrump. LHO bids two hearts, and RHO raises to four. Partner leads the ten of clubs.

Wow! It seems the opponents let me off the hook. I was lucky that South couldn't pass my one notrump advance to give his partner a chance to double. Was I not supposed to bid? My call seems fairly routine.

Declarer's likeliest shapes are 1-4-4-4 and 1-4-5-3. If he has 11 high-card points, that leaves partner with at most six--perhaps both black kings. Two kings? What kind of vulnerable overcall is that? Maybe he's five-five in the black suits, giving declarer a 1-4-6-2 pattern. That seems to be the likeliest construction. It also means we weren't in as much trouble as I thought. Two clubs wouldn't fare too badly.

Dummy plays the club ace. Normally, I would discourage to let partner know I have good diamonds. But partner doesn't rate to have much to do in this hand. Any signal I give will help declarer more than partner. So I encourage with the club seven. Declarer plays the six.

Declarer plays the heart three from dummy--four--jack--queen. Partner's side card is the heart queen instead of the club king? Even five-five in the black suits doesn't make this overcall look attractive any more. Partner continues with the eight of hearts--five--deuce--ten.

Declarer plays the seven of hearts to dummy's king. Partner discards the diamond deuce. That's weird. Why offer declarer any insight into the lie of the diamond suit? Why not just pitch from his five-card club suit? It's also somewhat surprising that declarer prefers to win this trick in dummy rather than in his hand.

Declarer plays the queen of diamonds. I cover with the king--ace--seven. So Partner wasn't five-five. He seems to have made a flaky overcall with 5-2-2-4. Since declarer has only one trump in dummy, I'm destined to take two diamond tricks. Declarer plays the three of spades--deuce--queen--six, then a diamond from dummy--ten--four--spade five. I play a club. Declarer wins and concedes a trick to my jack of diamonds. Making four.

Declarer has an extra trick in the end position. He's pitching a winner on the spade ace. Was a spade to the queen a practice finesse? I guess so--but only because diamonds were four-two. It would have been necessary to take the spade finesse if diamonds were three-three.

Declarer didn't time the play very well. He would have done better to start diamonds earlier. It would be nice to lead toward the queen of diamonds. But he doesn't have the entries to do that conveniently, and it's probably not necessary. Even if West has the king, leading toward the queen doesn't really gain anything as long as East can't overruff dummy. West would need to have king fourth of diamonds, a virtual impossibility on the auction, before declarer would regret starting diamonds from the table.

So declarer should play the queen of diamonds from dummy at trick two. East covers with the king. Declarer takes his ace, plays a spade to the queen, then plays another diamond to East's ten.

If East foolishly switches to a trump, declarer will make six. It is frequently a bad idea to lead trumps when declarer is about to embark on a crossruff, despite the propensity of many players to do exactly that. Playing trumps simply pickles the defense's middle-ranking cards and removes the threat of overruffs or uppercuts. East does better to play another club. (A low one, of course, so declarer will not know who has the club queen.) Declarer wins and plays a diamond. West ruffs in with the eight, forcing dummy's king. Declarer can still make six by playing a heart to the ace, but I see no particular reason for him to do so. He will probably take a losing heart finesse. But then he has the rest. Making five. Only two other declarers managed to make five, so plus 650 would be a respectable score.

Too bad I wasn't declarer. It's easy to see after the fact that starting diamonds from the table is the right move. It would be nice to confirm that I would have seen that before the fact. We get eight matchpoints for holding this to four.

  1. A friend has suggested that North should have passed over one spade, after which we would surely land in serious trouble. I agree, although passing does entail some risk. If partner has a 2-1-5-5 minimum, for example, I could not blame him for selling out to one spade in the belief that the hand belongs to the opponents and they are in the wrong suit. Still, the upside is so great that I'm willing to take that risk.
