Zenith Daylong - Oct 14, 2021 - Board 15

Board 15
Our side vulnerable

♠ 6   7 4 2   Q 10 8 2  ♣ K 10 8 3 2  

I pass in first seat. LHO opens with one spade, RHO raises to three, and LHO goes on to four. Partner leads the ace of diamonds.The robots lead king from ace-king. So this is either an unsupported ace or ace-king doubleton.

I don't want partner shifting to hearts from the king, so I encourage with the diamond eight. This says less about my enthusiasm for diamonds than it does about my lack of tolerance for a heart shift. Declarer follows with the four. 

Partner cashes the heart ace. I discourage with the deuce, and declarer follows with the nine. I expect partner to shift back to diamonds now. Having set up declarer's hearts, he needs to cash my diamond king if I have it. But he continues with the heart three--queen--seven--six. Apparently, he is playing me for the heart king despite my encouraging diamond at trick one. Fortunately, I have the diamond queen, not the king, so his play didn't matter. In partner's defense, my eight was a lazy play. It could have been my lowest from queen-ten-eight. I can afford the ten, so I should have played it.

Declarer leads the eight of spades from dummy and rides it to partner's king. Partner returns the spade five. Partner has shown up with two red aces and the spade king. With that much in high cards, he would have doubled one spade with the right shape. So obviously he has a doubleton club. That means I have a club trick coming and declarer is down one.

Wrong. Declarer has a stiff club. Making four.

This result is dead average. Every pair was minus 420. This is why it's hard to get a big score in non-best-hand tournaments. Sometimes you have no opportunity to do anything good--or even to screw anything up. In this deal, every decision of any consequence was made by a robot, who will presumably do the same thing at every table. So you are destined to get an average. 

I'm not sure why partner didn't double one spade. It doesn't look close. Thirteen support points, three honor tricks, and support for all unbid suits-- including four hearts. I'm not sure what more the robots think you need.

Also, the diamond ace is a strange opening lead. If you lead a club, declarer has to guess diamonds to make it.

Or maybe not. How will the play go? Declarer wins with the club ace and floats the eight of spades. West wins and returns a spade. Declarer wins in dummy and leads the club queen. If East covers, declarer makes easily. He ruffs, plays a heart to the queen, and cashes a club, pitching a diamond. This is the position:


NORTH
Robot
♠ 7 3 2
5
5 3
♣ 7






SOUTH
Robot
♠ A Q
K 9 8
K J
♣ --

He then leads a heart to the eight. West wins with the ten, and, since he is out of clubs, he is endplayed.

What if East doesn't cover the club queen? Declarer will probably ruff and play a heart to the queen. Declarer can still endplay West by ruffing another club and exiting with a low heart, but that would be a strange line. More likely, he will play a heart to eight. West wins with the ten and exits with his last club. Declarer ruffs, reaching this position:


NORTH
Robot
♠ 7 3 2
--
5 3
♣ J






SOUTH
Robot
♠ A
K 9
K J 4
♣ --

Declarer ruffs a heart in dummy, guessing whether to play East for a stiff jack or West for a stiff ace. Whichever one he tries, it doesn't work. So he is left with a guess in diamonds. Given West's failure to double one spade, he will probably guess wrong.

So far we are averaging about 60%. We have one board to go.
