generally doubles at some point in the game. This double wager amount is referred to as a big bet. For example, a four-round game called "20 and 40 limit" (usually written as $20/$40) may specify that each bet in the first two rounds is $20, and that each big bet used in the third and fourth rounds is $40. This amount applies to each raise, not the total amount bet in a round, so a player may bet $20, be raised $20, and then re-raise another $20, for a total bet of $60, in such a game. Some limit games have rules for specific situations allowing a player to choose between a small or big bet. For example, in seven-card stud high, when a player has a face-up pair on the second round (4th street), players may choose a small or big bet (e.g. $20 or $40 in a 20-40 game). Maximum number of raises Most fixed-limit games will not allow more than a predefined number of raises in a betting round. The maximum number of raises depends on the casino house rules, and is usually posted conspicuously in the card room. Typically, an initial bet plus either three or four raises are allowed. Consider this example in a $20/$40 game, with a posted limit of a bet and three raises. During a $20 round with three players, play could proceed as follows: Player A bets $20. Player B puts in another bet, raises another $20, making it $40 to play. Player C puts in a third bet, raising another $20 on that, thus making it $60 to play. Player A puts in the fourth bet (they are usually said to cap the betting). Once Player A has made their final bet, Players B and C may only call another two and one bets (respectively); they may not raise again because the betting is capped. A common exception in this rule practiced in some card rooms is to allow unlimited raising when a pot is played heads up (when only two players are in the hand at the start of the betting round). Usually, this has occurred because all other players have folded, and only two remain, although it is also practiced when only two players get dealt in. Many card rooms will permit these two players to continue re-raising each other until one player is all in. Kill game
