An action that isn't against the rules, but still incorporates unfair tactics.

Usage: A maneuver, usually on the border between legality and illegality (but usually clearly unethical), to take unfair advantage of another player. Extreme example: Some clubs consider putting fewer chips than required into the pot an uncompleted bet that is not valid until completed, and that, furthermore, can be removed until such time as sufficient chips are bet. (Fortunately, there aren't many such clubs.) In such a club, you bet $100 and another player puts in $99. You show your cards, which have him beat. He says, "I put in only $99; I didn't call your bet." He withdraws the chips. Of course, if he had you beat, he would quietly take the whole pot. If someone pointed out at that juncture that he called only $99, he would probably say, "Oh, pardon me, just an oversight; I meant to call," add the missing chip, and then drag the pot. All of that is part of an angle.
