[durrrr]

Weird spot for villain to bluff in, so I'd want to fold- but also very hard for him to have a hand he would pot the river with. Hands that beat you (that he'd bet) AA,QQ,77,44,AQ,A7,A4,4-x (AK maybe?)

I'd think AA,qq,AK almost always raise preflop.
AQ,77 often raise preflop, 44 sometimes, A7,A4soot sometimes.
He shouldnt be in there w/ 4x, A7,A4 too often, and i think he will often be afraid to value bet AK this much on the river.

This is very close imo, but i think i like a call
