Villian (utg) is a solid tag 20/15 regular. He probably views me the same. On the flop I don't think he check-raises with an 8 or a hand like AKcc. I think he bets out with those hands, hoping to push over a raise. Maybe he has 66, but I still think he bets out with that or check/calls. So I shove. Thoughts?
