Tough OOP hand w/ A3s

[Roadstar]

100NL 6m

Effective stacks $100
Hero image a bit aggressive, not nitty so can get some value from bets

Villain is largely unknown, small sample says hes 30/15 ish. I feel like hes floated me before but can't be sure i.e. I raise, he cold call, I cbet he call, i check turn, he pots.

Preflop, Hero has A[img]/images/graemlins/diamond.gif[/img]3[img]/images/graemlins/diamond.gif[/img]

Hero?!

Pot is like $90. Villain has $60 left commit him with a bet or check call to induce?

His range maybe something like QTs,QJs,KJs,AJ,sets,33-TT

If I bet is he committed to showing down with TP or PPs? I doubt the A on the turn helped him except for AJ.
