My tenth hand at the table. Villian has done nothing to get my attention.

Cryptologic

Pre-flop: (6 players) ThePwnz0r is UTG with
Hero raises to $4.5, 2 folds, Button calls, SB calls, BB folds.

SB checks, Hero bets $12, Button calls, SB folds.

Turn: ($38.5, 2 players)
Hero bets $22, Button raises all in for $46 more. Hero?

Would it matter if he min-raised?

If this post is way too easy/boring, I appologize. I'm up in NL overall but on a horrible losing run with aces.

Yeah I actually meant to bet 2/3 pot I just screwed it up trying to hurry. Either way though, I don't think at these stakes too many players interpret $22 bets into $38 pots as weak.

I don't mind him checking behind either, the problem is what do you do if he bets?
Say I check to him, he bets, now what?

3 things can be going on in this hand

#1) I have him beat and he's drawing slim.
#2) He has me beat and I'm drawing slim.
#3) I have him beat but he has a draw or combo draw.

So what's most beneficial? Check/calling resonably priced bets down, leading and folding to a raise (check/calling the river if he calls turn), or check/folding?

I personally feel check/folding is way too weak-tight here, but I'm really curious as to what others have to say.
