Villain here is 26/23 over 30 hands. i haven't yet played a pot with him postflop. I've 3 bet him once BU vs MP to which he folded. I've been fairly active but he hasn't seen me get out of line yet.

Flop: I assume he's c betting a lot here so AJ should be strong enough to float in position, I wouldn't expect him to barrel to many turn cards. Some of the ones he barrels make me top which is nice. I bet the turn to fold out all his medium/weak one pair type hands and AQ AK. I plan on firing a lot of rivers because his range will be capped at weakish 9s i would say when he c/cs the turn.

I think this river makes the board scarier to him and I can rep straights and sets. Thoughts?
