To stay in, players can call (put in an amount equal to the size of the BB) or raise (increase the amount). If they don't want to stay in, the player folds and hands in their cards. Players must now decide if they would like to move to the next round with their cards, starting with the player to the left of the BB. Everyone then receives two cards face down. Whoever has the button is the dealer, and the two players to the left of the dealer must post the SB and BB before the cards are dealt. There are four potential rounds for each hand: Preflop, flop, turn and river. NLHE is a pretty simple game as poker variants go. Like the button, blinds also rotate around the table, moving one seat each hand. The SB is generally half the size of the BB. Most games of NLHE have two blinds - a small blind (SB) and a big blind (BB).
The button is used to track who holds the dealer position, which rotates (clockwise) one seat each hand. Let's highlight a few key terms before we dive into a discussion of the rules of the game.
