I like your line here. Price is too good for a fold OTR. Let him spazz out once in a blue moon...we can’t just simply fold 2nd-nuts here ever vs an unknown imo.

I don't mind the check on the turn, principally because being raised here would be pretty awkward.

On the river, I don't like calling villain off. Pot odds are like 3:1? I don't think unknowns on NL25 have enough non-nut hands here to justify calling.

I like large sizing on flop pot bet or small over bet. QQ need some protect vs Kx Ax and get value Jx TT while board no so scary. Turn check or some block bet 1/2 pot both line good. River you can bet pot and fold vs raise. For how you play all options are not a big mistakes call and fold.

I don't hate the line here, but I would ch/c or b/f river, unless I have evidence villain is capable of spazzing here. We have plenty of Ac ourself so our river bet range is protected, we should have more Ac than him.

There is an argument for bet turn but you don't like getting raised, whereas you can comfortably ch/c.

You can ch/c riv to protect your non-club hands (you have a lot of these). I would strongly consider doing this, but can definitely miss value this way.

It is not that easy for him to have a lower club here. His turned flushes are betting and he shouldn't have many unsuited hands, so his lower flushes are only pocket pairs like TT, 88, not that many combos. It's also not easy for him to have Ac, he has to flat 3b and float the flop with AKo/AQo or slowplay a turned nut flush. If he is going to float some high card hands they will often contain Ac.

If he is a passive fish who calls the 3b with AJo and ATo then suddenly he has loads of Ac and we should definitely not b/c river.

I like your line, fold river. He's never raising worse for value and I doubt he's bluffing a quarter of the time, given that you are going to have more Ac then him. If he's a spazz, he probably would've spazzed out on the turn check rather than against the river bet....
