[deepsquat]

Just looking for a general line vs an unkown with Ace high at $1/$2

You open raise on the button with A [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/heart.gif[/img]

Uknown BB calls.

BB bets, Hero?

I generally raise all of these, bet the turn and check behind on the river. If im 3bet on the flop i fold.
Whats a better line?
