In a poker tournament, the act of not placing a bet when other players are in the same pot as a player that is all-in. Thereby increasing the chance of the player that is all-in being knocked out. Two hands are better then one.
Jim goes all-in due to being blinded out. Tony calls. Bill calls. Everyone else folds. The flop comes. Bill bets 1000 chips. Tony folds. Bill has demonstrated a classic example of lack of Final Table Courtesy. He has lowered the chance of knocking Jim out.
