for $6 and all raises must be for $6. As in no-limit and pot-limit games, these amounts will be over-ridden by table stakes rules (so for example, in $3/$6 fixed limit Hold 'em a player could bet, raise or call for only $2 at any time if that is their remaining stake). Also, in fixed-limit and spread-limit games most casinos cap the total number of raises allowed in a single betting round (typically three or four, not including the opening bet of a round). For example, in a casino with a three-raise rule, if one player opens the betting for $5, the next raises by $5 making it $10, a third player raises another $5, and a fourth player raises $5 again making the current bet $20, the betting is said to be capped at that point, and no further raises beyond the $20 level will be allowed on that round. It is common to suspend this rule when there are only two players betting in the round (called being heads-up), since either player can call the last raise if they wish. Pot-limit and no-limit games do not have a limit on the number of raises. If, because of opening or raising, there is an amount bet that the player in-turn has not paid, the player must at least match that amount, or must fold; the player cannot pass or call a lesser amount (except where table stakes rules apply). Call To call is to match a bet or match a raise. A betting round ends when all active players have bet an equal amount. If no opponents call a player's bet or raise, the player wins the pot. The second and subsequent calls of a particular bet amount are sometimes called overcalls. This term is also sometimes used to describe a call made by a player who has put money in the pot for this round already. A player calling a raise before they have invested money in the pot in that round is cold calling. For example, if in a betting round, Alice bets, Dianne raises, and Carol calls, Carol "calls two bets cold". A player calling instead of raising with a strong hand is smooth calling or flat calling, a form of slow play. Calling in the final betting round when a player thinks they do not have the best hand is called a crying call. Calling
