Villain is 48/28 with 18% 3bet over 40 hands (so could still partially be a heater skewing his stats). This is the first time I've seen him get 3bet so no idea what his general tendencies are there.

Postflop, doesn't look crazy (although obviously a very small sample) - seen him donk 1 flop of 6 opportunties (no stats for turn donk I could find), and has folded to 50% of cbets.

The turn donk is probably a spot to just get the money in or fold, but his sizing kind of threw me - do people like just shipping over his turn donk?

River, I've only got to be a good a third of the time. I wonder if he has enough Tx to make it a call?
