100NL, tricky spot against Aggro opponent OOP

[ungar2000]

Villian is 33/25 and is aggro. He seems to 3 bet lightly and does make moves on pots IP.

I have his 125.00 covered.

Hero checks, <font color="#cc0000">Button bets $18</font>.

What is the line to take here?

I think the PF call is awfull. What is your plan on flops where you don't hit a set? If he is 3-betting light, your call can't be justified by implied odds. He simply doesn't have a big hand here often if he is 3-betting light. I'd rather 4-bet here then call, tbh.

Plus, calling gets you in tough spots like this on the flop. [img]/images/graemlins/smile.gif[/img]

I'm not sure, but I think c/r AI can't be bad when he has been 3-beeting alot.
