Villain is one of the better regs. Would you consider CRAI this river? Villain has $42 behind in a $27 pot. I think if he is capable of thin vbetting a K here I should CRAI. And since I have the Ah it makes it even better. I think if I 3-barrel I get called a lot by Kx. Is my thought process right here or is this just spewy?
