Bet and Blind Sizes

Games of poker are often described in terms of the size of bets or blinds used during the game. For example, 10/20 Limit Texas Hold'em is a game of Limit Texas Hold'em where the small bet is $10 and the big bet is $20. This document examines the meaning of this notation for our different poker variants.

Blinds vs. Bets

Blinds are forced bets that players must make in certain games of poker during the first round of betting. Generally, the big blind is equal to the minimum opening bet and the small blind is half the big blind. In limit style games, the big blind is the same size as the small bet.

Limit Texas Hold'em

X/Y Limit Texas Hold'em is a game of Limit Texas Hold'em where the small bet is $X and the big bet is $Y. In Limit Texas Hold'em, since the bets are a fixed sized that depends on the current round, the value of the small and big bets fully describe the different bets that can be used. In this game, the small bet is the size of a bet or raise during the preflop betting round and the postflop (second) betting round. The big bet is the size of a bet or raise during the turn (third) betting round and the river (fourth) betting round.

No-limit Texas Hold'em

X/Y No-limit Texas Hold'em is a game of No-limit Texas Hold'em where the small blind is X chips and the big blind is Y chips. Note that this is different from Limit Texas Hold'em since bets are no longer a fixed size.
