MPs, 5CM, strong NT.
I intended my double as takeout to show heart shortage, something in the minors and not wanting to go past 3NT if partner held a double stop. This should go off, but I failed to twig during the defence that partner had a spade void. The defence started with
♣AK, then she led a low diamond to my ace.
♠A and another takes it down immediately, but thinking declarer had
♦KQ doubleton and noting partner had led a low diamond, not a high one, I led a diamond back and that was the end of the defence, the only other trick my
♠A. I should have probably guessed anyway partner had a void since otherwise why didn't she switch to a spade at trick three?
That was a complete bottom, no surprise there. No-one found a minor slam (it's not a good slam), a couple were in 4
♥ one off, one other made 3
♥, but we should really be in a minor game, not defending, although getting them down would have given us nearly 75% on the board which would have been better than zero.
One day I'll learn to slow down and think things through a bit more rigorously.
So, you think declarer has KQ doubleton in diamonds. Why does make you think that playing a diamond back is going to do any good at all?
Also, you know that partner has AKxxxx in clubs. Those high hearts in dummy suggest that declarer has 6 hearts, but he also has 2Clubs and, you think, 2 diamonds
Since he is known to have 13 cards, being 6=2=2 in hearts and the minors, how npmany spades does he have?
And if he has 3, how many does partner hold? And why didn’t he lead his stiff?
Of course, partner rates to hold the diamond king, both for his 2C call and because he led low. However, the inference that declarer has spade length is unmistakeable.
In Hamman’s book, written with Manley, he said that too many people ask themselves the wrong question at critical times in the play. They ask ‘what should I do?’ when the correct question is ‘what’s going on?’
Ask the right question, and the answer to the wrong question is often clear.
I personally prefer to ask ‘what do I know?’
Here, we ‘know’ that Lho has 2 clubs, at most 2 diamonds ( he might well falsecard from Qx), and probably 6 hearts. Therefore he has 3 or 4 spades. Once partner didn’t switch to his stiff, he has a void.
Learn to ask the proper question. You will be amazed at how much you ‘know’ if you listen to the bidding. I put ‘know’ in quotes because one has to think in terms of probability much of the time...you suspect...you infer....certain things, with varying degrees of certainty, but here, I’d have a very high degree of certainty that partner has a spade void when I win the first diamond.
Slow down....stop asking yourself what to do and start thinking about what the auction, and play so far, has told you.
