Remark.—The remaining trump is in A's hand. But for the echo, it might be in Z's hand.
Trick 9.
Tricks AB, 4
YZ, 5
9. Z A Y B↷
5♣ 9♦ 8♦ A♦
Remark (Trick 9).—B can now lead ace of diamonds, without fear of its being trumped (see Remark, Trick 8). If the position of the other trump were uncertain, the lead of the ace of diamonds would be wrong. For, by leading nine of trumps, B can make certain of saving the game (see score); whereas, if Z has a trump, and trumps the ace of diamonds, B loses the game, as Y will then make a diamond.
Trick 10.
