Villain is Laggy and I have position on him, though he is not quite maniacal. He's running at 55/23/1.2 but only over 63 hands so the AF doesn't really count. He is involved in many pots and has min-raised a few times. I wanted a safe turn to push and the K looked as good as any unless I was already beat. What do you think?
