coup The Alcatraz coup is performed by purposely revoking when declarer is uncertain which defender to finesse. After the trick is over, declarer knows which defender to finesse, "notices" and corrects his misplay, and finesses the correct defender. Superglue coup The Superglue Coup is where a defender pulls out two cards together (as if they were superglued together). Declarer sees the cards and assumes they are adjacent in rank in the defender's hand. For example, if declarer is missing K103 and one defender pulls the K and 3 out together declarer can assume that the defender does not have the 10.
