This deal is from the Wednesday at Bramhall Bridge Club in early June. Bramhall have recently introduced duplimated boards, which is a boon to the deal of the week correspondent.
Here North-South made a number of dubious bidding decisions and luckily landed in a super-Moysian fit.
After East had opened one spade South overcalled two clubs, this would normally be a six card suit but, given the strength of the hand and the suit quality, was not an unreasonable call. After West passed North had a difficult call, he had good values, but minimal support and no spade stop, so he improvised with a bid of two hearts. South also had a difficult call. He had extra values, but not great heart support. He decided to raise hearts in the hope that a five-two fit would be adequate. North then elected to bid game. East cashed two spades and switched to a club. North won the club ace and cashed the top hearts, when the jack dropped he was able to draw all the trumps, take the marked diamond finesse and claim a very lucky eleven tricks.
