/** TODO
Maximum number of raises
Most fixed-limit games will not allow more than a predefined number of raises in a betting round.
The maximum number of raises depends on the casino house rules, and is usually posted conspicuously
in the card room. Typically, an initial bet plus either three or four raises are allowed.
Consider this example in a $20/$40 game, with a posted limit of a bet and three raises.
During a $20 round with three players, play could proceed as follows:
Player A bets $20.
Player B puts in another bet, raises another $20, making it $40 to play.
Player C puts in a third bet, raising another $20 on that, thus making it $60 to play.
Player A puts in the fourth bet (they are usually said to cap the betting).
Once Player A has made their final bet, Players B and C may only call another two and one
bets (respectively); they may not raise again because the betting is capped.
A common exception in this rule practiced in some card rooms is to allow unlimited raising
when a pot is played heads up (when only two players are in the hand at the start of the
betting round). Usually, this has occurred because all other players have folded, and only
two remain, although it is also practiced when only two players get dealt in. Many card rooms
will permit these two players to continue re-raising each other until one player is all in.
