The Fixed Limit Betting Structure
In a poker game, a player has to be able to match a previously made bet so that they can stay in a game. Another option a player can take is to raise a bet. Usually, a raise increases the betting amount to about twice its size. There are usually restrictions to how often and how much a bet can be raised though.
The restriction on how much can be bet and how much a bet can be raised is called a limit. Any poker game can have a limit. The four main types of betting structure limits are fixed limit, spread limit, pot limit, and no limit poker.
Poker games played using a fixed limit betting structure are arguably the most straightforward: a player either bets, or they fold. The amount of money being bet is set according to the rules. In some games, so that bluffing could be possible, the fixed amount doubles over the course of the game. When the amount has been double, it is called a "big bet."
In a poker game with four rounds and a "thirty and sixty limit," for example, the bet during the initial two rounds would be thirty dollars. Afterwards, during the third and fourth rounds, the new fixed amount, or big bet, is forty dollars. Usually, in a game like this, the limit is written as $30/$60, so that a fixed limit Omaha Hold'em game with these limits, for example, would be written as $30/$60 limit Omaha Hold'em.
In a fixed-limit game, raises are very limited, and usually, during a betting round, there are only a certain number of raises a player can make. The rules regarding the number of raises can depend on the house rules of the casino or cardroom offering the game. They are usually posted conspicuously, so that players can make a note of it while they play.
Usually, in a betting round, the betting for a fixed limit game consists of the initial bet, and around three or four raises.
For example, in a thirty dollar limit game, there is the fixed limit, and three allowable raises in a single betting round. Over the course of a single betting round, Player 1 will bet thirty dollars. Player 2 will raise it another thirty, making the betting amount $60. Player 3 also opts to raise the bet for the third and last time. They raise it another thirty dollars, making the amount $90. Given that the only players in the hand are Players 1, 2, and 3, Player 1 will put a cap on the betting, and Players 2 and 3 can no longer raise anymore.
