AA vs slag...Turn Play???

Villain seems kinda lag at 26/15 over 46 hands. If it matters, I am around 16/7 and almost always cbet heads up.

My thinking was that I beat most of a his range on the flop+turn which I estimated to be suited cards like Kx where x<J and 98/87. Pocket pairs and QJ seemed unlikely given his PFR stats but not impossible since the stats are on 46 hands. So I bet...

Surprise! He check/raises me on the turn! But he was lag so I decided to call to get more action from hands I beat (Kx and maybe a draw). At the time I put less weight on 7x even though it's what he's repping. I figured he would fold worse hands if I pushed over his check/raise but looking back that seems doubtful given pot odds. Anyway I basically had to call the river when I called the turn.

Would you check behind the turn? As played, do you call, fold, or raise to the turn check/raise vs this type?

Looks like a fold or push turn since you can't get away from it on the river anyway.
He's committed himself as well so he's calling you if you put it all-in on the turn if he has anything reasonable at all.

Dry board smooth-call on the flop, check-raise turn -- pretty standard set line. If he was floating you with bottom pair and a K on the board...yuck! If he's playing Kx this way - wow - buddylist.

Any comments on prior big hands from this guy? Also - what's his agro factor? I think that really comes into play as to whether or not you make these calls - assuming no other reads...if he's playing lots of hands and playing them very agro, you're gonna call in general and pay him off.

Nothing particularly wrong with the turn bet, assuming that you want to play for stacks against this guy. But he does tell you at that point that you are beat.

I didn't have enough history with him for a reliable aggro factor (although over 46 hands aggro factor was over 5 then and infinite for the turn) and was playing too many tables to see if he had a previous big hands. I know what you mean though about this being a set line, but he raised 15% pre flop but open limped in this one...he didn't seem the type to slow play pocket pairs.

I might as well say, in fact he WAS playing bottom pair on the flop! He had 8d7d. I think his logic was he had a lot of "outs" between runner runner str8 and flush draws, and two pair/trip possibilities, and I'd give him implied odds, which I sort of did.

It didnt' make sense to me that 7x calls pre flop AND on the flop at the time. I guess I should give turn raises respect even when stuff like that doesn't make sense, unless I've specifically seen somebody do it with junk.

Results aside, would checking behind on the turn be better? I didn't want to miss value if he had Kx.
