He is running 15/8 over 60 hands. Only hand that he has shown down was KK, which he popped for 11xbb pre, then checked down flop turn and river. Range pre I guess TT-QQ, AK. So flop, AK add 77 which I don't think he has pre, slow played AA, but this guy plays his big hand aggressive pre, not post flop. The only hands that really make sense are AK and what? This is the first time he has called a 3-bet pre, so how much wider do I need to make his range?
