Trick 1.—A leads from his long suit, and Z wins the trick with the singleton ace.
Trick 2.—The dealer, having eight clubs and eight spades in the two hands, has now a choice of suits. The king of spades must make against him while he has a finesse in the club suit. If he leads the clubs first he is compelled to guess in which hand to take the finesse; he therefore leads the spade, hoping by establishing that suit to force discards and find out where the two queens are.
Trick 3.—B might make it more difficult for A by not playing the king of spades.
Tricks 5, 6, 7, and 8.—A's two discards of clubs show that the queen is not in his hand, while B's heart discard indicates that he does not hold the queen of hearts. The queen of hearts is also marked in A's hand by the fact that he is discarding his winning diamonds and protecting hearts.
