I'd be folding the river, we lose to every Ax and the turn completes the flush. Yes we're getting good odds, but I expect to be beat here fairly often.

Ugly spot. I don't think this is one where villains will typically try to vbet worse (ie, 99 type hands). Ax pot controlling on the turn makes sense. Stuff like 76/87 have trips now and the flush came in. Unless villain is betting just super wide on the flop it'll probably be tough for him to bluff a lot here. It's also not a sizing I'd think is being bluffed often also.

While calling the flop is totally fine the river is getting super close. Given the fact that most NL2 players won't be able to vbet thinly and won't have high bluffing frequency I'd go ahead and fold.

Given the positions it might be ok to bet around 20c on the river as a blocking bet and for thin value. I think it's likely that villain stabs his pairs on the flop and bets any Ax on the turn having position and the possibility of checking back the river.

As played I would fold the river as I don't expect him to bluff a hand such as TT,nor will he be bluffing in general enough at 2NL.
