Villain 35/24 over 60 or so. Opening wide everywhere, so his button range doesn't seem to be something like 90% here. Stats show 40% spread across positions. He has 4B once before when OOP, but his sizing was 20bb rather than ~26bb (the guy 3Betting him was only 120bb deep though).
I feel like I should fold turn, otherwise I have to call this river since any Ax hearts should just be able to ship rivers. But then he might also have 10 or so combos of flushes.
If I'm in villains shoes with Ahx air should I be taking the bet turn shove rivers line as a default?
