Uncertain with ATs

[Quercus]

Villain in this hand is 60/20ish but I don't have a huge number of hands with him. On a previous hand, he pushed all in on the turn against me for a decent sized pot and got me to fold. I've got a sneaking suspicion that he made a move on me there but one of my leaks is seeing people making moves when they are just playing their two cards.

I'm 23/13ish and aggressive postflop. Table has been letting me steal their blinds and limps and folding with regularity to cbets. Haven't been a lot of showdowns other than an AA versus KK preflop all-in that doubled me up.

BB ($25)
UTG ($19.17)
MP ($24.40)
Hero ($65.50)
Button ($22.60)
SB ($46.50)

Preflop: Hero is CO with T[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/heart.gif[/img]. SB posts a blind of $0.10.

Villain's hand range is pretty large here. What two cards won't he limp with though? What would he limp in with and call a PFR raise with? I feel like I should have a feel for this, but I don't (not just against villain, but in general).

<font color="#CC3333">MP bets $3</font>, Hero calls $3.

Plan is to call here and pop a safe turn. Is that too LHE thinking?

MP checks, <font color="#CC3333">Hero bets $5.81</font>, MP calls $5.81.

Turn is safe, villain checks. I bet 2/3 of the pot. I chose 2/3 because its enough to give improper odds to draw to a flush, but small enough to still induce a call from a lot of players. Its also small enough for weaker hands to come along and I can also get away from it if villain comes over the top allin.

MP bets $14.34 (All-In)..

Hrmm, ok. Definitely not what I expected to see on a blank. My TP doesn't seem so good here anymore. Did I just get beaten by A8, is villain making a play?
