In Pot Limit, any player can raise any amount within a range defined
by the size of the pot at the time of the player's turn to act.
Minimum raise: The raise amount must be at least as much as the
previous bet or raise in the same round. As an example, if the first
player to act bets $10 then the second player must raise a minimum of
$10 (total bet of $20).
Maximum raise: The size of the pot. The size of the pot is
defined as the total of the Pot in the middle plus all bets on the table
plus the amount the active player must first call before raising.
To see how the calculation of the raise limit would work, assume
you're playing a game with $1-$2 blinds. The next player can fold,
call the $2, or raise by placing between $4 and $7 in the pot. If the
player bets $4, he's raised the minimum, because the previous bet was
$2, and he's doubling that.
If the player bets $7, he's betting the maximum, because he's
first calling the $2 blind bet, creating a total pot size of $5, then
raising the size of the pot. The $2 call plus the $5 raise yields the $7
bet.
Let's assume the first player to act does bet $7. The pot now
contains $10. The next player to act could fold, call the $7 bet, or
raise by betting between $12 and $24. This is proper because the minimum
raise is $5 (the size of the previous raise) and the maximum $24 (by
calling the $7 bet and then raising the size of the now $17 pot)
If several consecutive players make pot-sized raises, a pot can
escalate dramatically. We recommend that beginning players play limit
poker before advancing to pot limit.
When playing at Poker-Flush you have a betting "slider"
which allows you to bet many amounts between the minimum and maximum
allowable bet size.
At each Pot Limit table there is a Maximum Buy-In amount. Poker-Flush currently has three different maximum buy-in amounts of $25, $50
and $100.
