Finesse - Pseudo-finesse


A pseudo or "Chinese" finesse presents a declarer's deceptive move to fake a high-leading finesse by leading an unprotected honor, hoping that the defender will misread the situation.

♠ A 7 4 3
♠ K 6 5 W N↑ S↓ E ♠ 10 8 2
♠ Q J 9

♠ A 7 4 3
♠ K 6 5 W N↑ S↓ E ♠ J 10 9
♠ Q 8 2
