1. "refill"
should not be able to refill while still in a hand.

2."side pot"
In a multi-way pot, a sidepot is created for other players if one player goes all-in. These other players bets and raises will go to the sidepot, and only the players that participated in the sidepot are eligible to win it.

3."betting"
a player should never be allowed to bet lower then the blind.

example ( if blinds are 5 and 10 i should never be able to raise 1 chip).

1 is fixed

2 is semi

3...if the actual bet is 10...and u raise 1...it produce 2 msgs if u notice the log .."player x call 10 and raise 1".
So a raise allways equal the bet..before raising it.
