tough 55 hand

[wdeadwyler]

I think villain could of easily backdoored into a flush with hearts and think you have a king or something. Is he the type to semibluff this turn? He could also have something like AQs and have thought his hand was best.
I'd put him on QQ, a flush, or trips kings most likely (It is weird to check the kings twice I agree).
I dont like folding here to an unknown, you said you only hand 30 hands on him. What does the massive overbet from this player make you think?
