The Full Deal
The opening lead was the Jack of diamonds to the Ace; West ruffed the diamond return and led a club to the Queen and Ace. Ace-King of spades (pulling trumps). Now the contract depended on finding the Queen of hearts. Declarer led a club which West won with the Jack. The King of clubs came back, East showed out, and declarer ruffed. East had seven diamonds (proven), two clubs (proven), two spades (proven) and therefore two hearts. So the odds favored the Queen of hearts lying with West (who had three hearts versus East’s two); on that basis declarer played the Ace and ten of hearts intending to run it if it was not covered. West did cover (not best defense) and declarer had plus 620 for a 90% score.
Of 58 NS pairs, 21 (36%) bid four spades (13 making for 90% and 8 going down one for 9%). 23 (40%) played a part score (making ten tricks 16 times for 66% and nine tricks 7 times for 46%). 14 pairs (24%) passed the hand out for 25%.
Bonus from Val: After the defense starts with a diamond to the Ace and diamond back (ruffed), ten tricks depend on declarer playing West for the Queen of hearts. If (not on this layout but on a different layout), EW had sacrificed in five diamonds, plus 300 would have scored in the high 70s for NS. Deal V103.
