H1:
Villain is a10/9/2.7 tag over 400 hands, folds to cbet 60%.
Once he called flop, I figured either he had an Ace or 77 in which case the money was going in regardless or alternatively a pp that thought he'd float the flop as my cbet stats were approx 80+% which is why I checked the turn, thinking he'd smell bullshit and might try and take the pot getting me an extra bet that I might not have got if he didn't have Ax/77/55 or if he checked, I might get a bet from on the river that from hands that would have folded to the 2nd barrel on the turn.

Villain was a nitty 12/10/6.2. His cb stat was on 40% which made me think he was quite cautious and might be scared of a set which made me think I had enough fold equity to shove over what I guessed was an overpair or set.
