To make a long story short, don't tell it.
We all make mistakes at bridge. I know - and teach - that learning from errors is a path to improvement, but when a player simply has an aberration, I don't much want to hear about it.
At 3NT in a Chicago game, South captured East's king of spades and, without thinking, took the A-Q of clubs and then three more clubs. East threw a heart and three diamonds, and declarer, who had to discard twice, let go a diamond and a heart.
South next led a diamond to his jack. When West took the king, he shifted to a heart, and when East won and returned a heart, West took three more hearts. Down one.
South had a mind cramp. After East-West followed to the ace of clubs, South could assure nine tricks by leading the ace and queen of diamonds. Or, when West followed to the queen of clubs, South could safely overtake with the king to finesse in diamonds.
I heard about this deal from North. He should have made a long story short.
You hold: ´ A Q T Q 10 7 5 © A Q J 4 ® A Q 6. The dealer, at your right, opens one spade. You double, and your partner bids two clubs. The opponents pass. What do you say?
A: You have 21 high-card points, and if the opening bidder holds in the neighborhood of 13, your partner may be busted. Still, he might hold a hand such as today's North hand. Bid 2NT, showing great strength. If partner has a possible source of tricks, he can raise you to game.
