In Texas Hold'em, there are usually four types of betting structures: No-Limit, Pot-Limit, Fixed-Limit, and Spread-Limit. The most common is No-Limit Texas Hold'em, where players can bet any amount of their chips at any time during the hand.
Betting proceeds in a clockwise direction, starting with the player to the left of the dealer. Initial bets, known as blinds, are posted by the two players to the left of the dealer to stimulate action.
