In Pot Limit betting poker tournaments, in any betting round, bets and raises are limited to the current size of the pot, enabling the pot to grow geometrically.
Regarding raises, in Pot Limit poker betting, the size of the pot embodies the call.
For example, if there is $1000 in the pot at the beginning of a round and one player bets $1000, another player can call the $1000 and raise the size of the pot to $4000. As long as the size of the raise is equivalent to or larger than any prior raise or bet in the same round, any of the players can raise a smaller amount than the maximum.
Since poker tournaments may vary in their calculating method regarding Pot Limit betting , many major tournaments notify the players of the maximum opening raise sum whenever the limits are increased.
