Villain seems to be a decent reg in my sample. Opens 31% in co and folds 58% to 3bets, 4bets 3% range from co.

Flop and turn play themselves I think. On the river I go for value vs smaller Ax since I think he bets everything that beats me on turn as there's a lot of bad cards for all of those hands. And then he jams, not really repping much imo. 98s, 88, A8? I can't see him checking better on turn. He raises only 3% of cbets otf in 3b pots, and 2% ott. Then it goes to 20% on river. He also bets between 28-38% wct in 3b pots.

I'm quite close to top of my range if I care about that. I also block Qd fwiw.
