In limit play, an all-in wager of less than half a bet does not reopen the betting for any player who has already acted and is in the pot for all previous bets. A player who has not yet acted (or had the betting reopened to him by another player’s action), facing an all-in wager of less than half a bet, may fold, call, or complete the wager. An all-in wager of a half a bet or more is treated as a full bet, and a player may fold, call, or make a full raise. (An example of a full raise on a $20 betting round is raising a $15 all-in bet to $35.) Multiple all-in wagers, each of an amount too small to individually qualify as a raise, still act as a raise and reopen the betting if the resulting wager size to a player qualifies as a raise.
