Villain is 32/20/6 through 325 hands. Fold to 3bet, 56%. Doesn't seem positionally aware, playing 35% of hands UTG. Fold to cbet, 65%.

Notes on villain: Had seen villain defend BB with 32s. C/c flop with bottom pair, check turn, and attempt a bluff on river, around 1/2 PSB.

Felt like I opened the door for him to bluff the river when I checked the turn, I have no idea why I did that either as I thought it unlikely that he had an A given how wide his range is.

Can he be bluffing here with some stupid 9x or a busted FD or is it an easy fold?
