Betting Rounds
The two most common betting formats for Texas Hold em games are called ?Structured betting? and ?Spread-limit betting?. In a structured betting game, each bet and raise is a fixed amount, and usually that fixed amount is one amount for the first two betting rounds and twice that amount for the last two betting rounds. For example, in a $3-$6 structured betting game, all bets and raises in the first two rounds must be exactly $3, and all bets and raises in the last two rounds must be exactly $6. In a spread-limit betting game, say a $1-$4 spread-limit game, any bet or raise during all four betting rounds may be any amount between $1 and $4, with the exception that raises on any particular betting round must equal or exceed any previous bet amounts (i.e. if someone bets $3, then any subsequent raises must be $3 or $4). Some spread-limit betting games increase the available betting amounts in the last two betting rounds. Typically each betting round is limited to a maximum of three raises
