Trump Coup & Endplay

by Richard Pavlicek

A trump coup operates like a trump finesse, except a plain suit is led, and the finesse is achieved by an overruff. A trump endplay simply forces an opponent to lead the trump suit for you. The two techniques are closely related, as both attempt to gain a trick in the trump suit itself. Also included here is the smother play and its variations.

1.  Trump reduction and endplay
