Villian is competent. He runs LAG at 24/20/2. His fold to a Cbet is 28%. Against normal opponents I would continue betting. Against this guy I thought it would be a perfect spot to CRAI on the turn. Do you like this play here? As played my hand is under repped and I think we may have to call the river. I really can't see a hand that I beat that villian is doing this with that we beat. Call or fold the river?

Wow wtf? I think the turn check is definitely good, but I probably punch the table and throw the hand away on river. I think he has a set here a lot of the time.

The river raise is really really strange. I have no idea what hand plays it this way except 55 or Ac2c or 7c6c etc.

I would fold river if I thought he was a competent player.
