Villain unknown, unfortunately (the hand would've been really easy had I known his stats).

Pre-flop: (6 players) Hero is CO with Q/images/graemlins/spade.gif A/images/graemlins/diamond.gif
UTG folds, UTG+1 calls, <font color="#cc0000">Hero raises to $2.5</font>, Button folds, SB calls, BB folds, UTG+1 calls.

Flop: 6/images/graemlins/club.gif 3/images/graemlins/heart.gif A/images/graemlins/heart.gif ($8, 3 players)
<font color="#cc0000">SB bets $5</font>, UTG+1 folds, Hero calls.

Standard would be to raise the flop, not sure why I didn't.

This push just doesn't make any sense. A blank comes rolling off (unless he has exactly 45 or A2) and he still open shoves. Is this ever a monster? Do I call or fold?

you needed to have raised the flop.

but, as i read this i think fold. in the hand I might play it differently depending on the feel of the hand. Also, with AK i think im more inclined to call.

pretty easy fold. I can't imagine what you are beating. I also can't imagine what SB is pushing with though?

thats the thing, we dont have enough information to play this correctly. all we can do is make an educated guess.

Villain smooth called preflop. lead the flop for 2/3 PSB. and Open pushed the turn. hes either 1) FOS, or 2) not afraid of anything (remote possibility = hes retarded). if we arent ahead right now, we are more than likely drawing dead.

a set is possible and so is a str8 as well as AK. we have to fold.
