re: Poker & You can give more of a re-raise?
all no limit and pot limit games have unlimited raises
the rule is like this - any raise must be equal to or greater than the previous bet (or raise). If I bet 20, the raise must be 20 or more on top of that bet (so 40 minimum or more). If I bet 20, next raises to 50 (+30), the next raise must be +30 (or more) of total bet (50) so the bet would need to be 80 total or more, the ONLY exception to this minimum is if a player moves all in (for less than the minimum required)
not sure how to make it more simple, hope this helps
now where it really gets tricky is when the hand is 3 or more players and what constitutes the ability to raise again. if you want to know more about this let me know, its a long response
