BB with Ax vs button (and a return)

[avidlearner]

hi all-

i posted a some last year and read the forums a ton. decided to start participating more due to my game suffering from lack of work but forgot my account info. since this is sort of a fresh start, i suppose a new account is better [img]/images/graemlins/smile.gif[/img]

anyways, my question.

assume a middle limit online game, the button has average aggression. well probably tries to steal too much, but not a maniac. you play better than him post flop.

what does X need to be in the Ax combo for you to 3-bet?

lets break it down further:

SB calls
SB folds

i know there are metagame issues to be considered, so bring those into discussion if you like.

thanks
