Hmmmm, this feels gross and the kind of spot where we got fucked by making two pair OTT. Going by that I would say it is a fold but in game I probably sigh fold every time lol.

Tbh I'd consider all options on river. If villain is aggro pre he shouldn't often have better 2 pair or a set so against a range that is either a straight or worse than A5, A5 makes a decent bluffcatcher.

For that sizing (and the fact the 3 barrel donked) I'd expect close to zero bluffs unless they're made hands turned into bluffs. For this sizing though I think he's value heavy. If I think he's not bluffing often enough then fold comes to mind.

But when he chooses this sizing I think it's one he might make with more than just straights, assuming he has some big-ish 2-pair combos in his range and therefore a raise might be decent.

pfft

I think I'd go with a fold and just like @CrazyCookie it would be a sigh fold.

Side note, if villain is a decent reg he should basically never be leading this flop, so keep an eye on him if you play often. Doing stuff like this is pretty exploitable in one way or another.

I just don't think an average NL4 player will bluff often enough on those kinds of boards to justify a call, but at the same time I probably couldn't fold this in game for the sizing.

Thanks for comments.I was thinking about raising this river but the hands that I raise for value here AJ,QJ and nothing much,with QJ I might raise flop or turn sometimes.I won't have many KJ or JT combinations I think.So my value raising range seems to be so narrow I assume.There's small chance he would bet with weaker ace or KT 3 times.Other than that I don't find many weaker hands.

I agree with the others about folding the river.

It's easy to cry pot odds with the bet sizing, but more often than not it's going to be a better two pair at least hoping for a crying call for a hand like what we have. Pretty sure he never has Jx as played, but I doubt it's KTs either.

Flop call is fine. Obviously call again on turn when we pick up the second pair.

River will typically be a fold, despite the great odds we get. He is probably unlikely to be bluffing for that sizing. It really depends on if he can ever value-bet worse. I doubt calling would be a huge spew or anything, but I imagine folding has the best EV.
