villian is 16/13/2 over 230 hands. His ATS% is 27%. Should we puke and fold on the river vs his fucking hand?

Can't see how this is a bluff or worse than AK....or even AK for that matter.

I just realized that I should've checked behind on the turn and called any river bet in this case.There are really not many worse hands in his rang which he is willing to call with. Poor turn play on my part.

Or check flop and bet turn/river. If you get stacks in here you're usually going to be a dog/chopping so we're not going for 3 streets (obv).
