Automatic Bluff
A bet, often a bluff, made, regardless of one's cards, in a situation in which the bet usually wins. For example, in a lowball game, if one player drew four cards and passes after the draw, and the next player drew one, the latter almost always makes an automatic bet, because most of the time that player has the best hand and the few times that he doesn't, the drawer of four cards doesn't call anyway.
