This deal is from a local duplicate.
After West opened one heart, South played in six notrump on the queen of hearts lead.
Declarer knocked out the spade ace, the defence continued with the jack of hearts.
Declarer now cashed all the spades coming down to the club ace and AKQ10 of diamonds. When the diamond jack failed to drop the contract was one off.
However, declarer could have done better, can you see how?
Declarer should have thrown the club ace on the last spade and kept AKQ103 of diamonds. Now West is squeezed in three suits and has to give up either a club or heart trick immediately, which will allow declarer to cash a top card in that suit repeating the squeeze, or throw away the diamond guard giving the declarer two extra diamond tricks.
Thanks to Raymond Semp for reporting and analysing this deal.
