The most defining element for a game is its betting structure. There are three different forms of betting in poker tournament. They are:

1. Unstructured betting This betting is usually called as no limit. When a player fixes a blind, brings-ins, or antes then he or she is allowed to bet as much as they wish, and can even bet in at the earliest stage in the betting round. Betting all chips of a particular player is called as the all-in. In this type of no limit tournament the players even takes risks even at the former stage of the betting round. Say for example, in a no limit tournament like Texas Hold’em tournaments, the players use to bet all-in even before the flop.

2. Semi-structured betting This betting format offers some ranges for allowed raises. In this format of betting no player should raise lesser than of what have been raised by the previous player. As an example, if one player of the game raises $10, the other players have to raise more than $10. Pot limit is a semi structured format where no player can go beyond the pot current size. Another semi structured format is the Spread limit where it should consent to the bets only between the maximum and minimum amounts.

3. Structured betting This format is also called as fixed limit betting system, where the raises and bets are restricted to a fixed amount. Also these amounts will get increased throughout the tournament. Example: if a seven-card stud tournament has a stakes at 10/20, then the raises for the first 3 betting rounds would be $10 and the later rounds would be $20.
