At first glance this looks a bit of a sigh call situation. But at second glance, I fail to see how he can value bet worse here. I'd hate it, but a disciplined fold here is prudent. There's a ton of hands that got there on this river, and I'd probably die of old age before i finished listing them here.

When the deuce pair you should go bigger to extract from near the top of his range there, KQ (he may also have A2 there). The river is sick, but I would x-c this bet size otr. Since you bet so small ott he may have random 64hh or similar there. 

Sigh call i guess, hope he bets some worse 2pair like K9

Another thing, having the Ace of hearts here is pretty irrelevant. You block the nut flush, but every single player out there would still bet a Jack high flush in this spot. This is a PLO concept.

In fact, it might even be bad for our cause, as you block AK and AQ, two hands that he could conceivably value bet on the river, two hands that you want to value bet.

Seems like a call, he could be value betting worse hands with that sizing. He almost always has something showdownable here, so there are very few bluffs in his range unless he is turning qx, 9x into a bluff. But he will value cut himself often enough to make this a call.

Turning hand into a bluff is reasonable, but probably not against the average opponent at this stake level.

If I don't feel like I can bet for value in this spot then I would just c/f.
