Flop bet is a little weak. We want to get our V's to fold all of their weak Kx's. that C/R on the turn is weak. that needs to be like 195.
As played, you are getting 2.5:1, so the is definately callable.
his turn bet is strange. He is repping something like A
Kx. So 30 into 96 is really weak. or, maybe he has already made the nut flush and is just valuetowning you.
I would lay this down. It looks like he turned the nut flush.
