I've been beating up on villain without getting to showdown. He's a pretty normal reg that I haven't noticed doing anything weird other than seeming a little weak-tight in general.

Last hand we played, I flatted his utg (5 handed) raise and bet a low flop after he checked to me. He insta-folded.

game is nl5-10, eff stacks 900$

Villain raises from CO, I flat KQo from btn. We see a flop HU.

Flop (85$) is

He checks, I bet 60, he calls pretty quickly.

Turn is

He checks, I check back (I think this is the big question in the hand fwiw)

River (205$) is

He bets 165 pretty quickly...
