Using unfair tactics.
Usage: A poker player who uses various underhanded, unfair methods to take advantage of inexperienced opponents. The difference between an angle shooter and a cheat is only a matter of degree. What a cheat or thief does is patently against the rules; what an angle shooter does may be marginally legal, but it's neither ethical nor gentlemanly. Nor is it in the spirit of the game. Unfortunately, poker is not a gentleman's game. In addition to learning how to protect yourself against cheating players, you must learn to watch out for the angle shooters. See "Angle".
