Remark (Trick 6).—The lead here is the point in the hand. Y has three tricks up; there is a whole suit (clubs) against him, and his adversary B has called for trumps (see Tricks 3 and 4). It is, consequently, Y's duty to make five tricks (which save the game if Z has an honour) as quickly as possible. He therefore leads the ace of spades to make the fourth trick, and (Trick 7) forces his partner (though without any strength of trumps in his own hand, see pp. [132], [133]) to make the fifth.
