Villian here is a reg and running 25/19 over 550 hands with a 22% raise cbet over 18 samples.

I think the flop is a standard call, I don't think he raises AJ here for value so his range is pretty much bluff heavy. Hands like QT, 8T, might play this way maybe even KQ. Once the turn checks through I think I make a mistake and should make a small value bet for hands like QT/8T to call that may not be able to find a fold, his WTSD is 24 which makes me think a small bet will be better.

I check and he bombs river, I don't see many combos of flushes that don't bet the turn and he bets value hands such as sets & 2 pair on the turn. I'm trying to think of a hand that might play this way which could be KQ?
