Poker is typically played "table stakes", meaning only the chips in play at the beginning of each hand may be used throughout the hand. This means that the player cannot get additional funds from the cashier while he is in the midst of a game. The table stakes rule has an application called the "All-In" rule, which states that a player cannot be forced to forfeit a hand because the player does not have enough chips to call a bet.
