Negative freeroll occurs in poker when a player places an all-in wager on a hand that can only either tie or lose. A negative freeroll is relatively common in low stakes amateur play, but in higher stakes play, it is considered a serious blunder to allow a negative freeroll on the final round of betting due to the amount of risk involved. Negative freeroll usually occurs in no-limit or pot-limit when contemplating an all-in wager, where the player acting first checks in a situation where they would be forced to call an opponent's final bet (due to pot odds and the strength of their holding). If the opponent has a stronger hand, the opponent will most likely bet and the player will call and lose all their money regardless. However, if the opponent has a weaker hand, betting may be the only way to get the opponent's money into the pot, as checking allows the opponent the opportunity to check in turn. It can also refer to a situation where one is faced with a bet and is considering raising instead of calling. If the betting player has a indicating that he is either betting with the nuts or is bluffing, raising with a made hand is a negative freeroll, since the expected value of calling and raising are identical when the betting player has a bluff, but the expected value of a raise is worse than a call when the bettor has the nuts.
