I couldn't get the HH. $320 online MTT. I am probably unkown to villain and show up as tight if he is using a HUD. Original stacks 100K, average stack about 400K. Blinds 5K/10K with ante. UTG+1 with 630K opens to 20K. I have AA and 145K in CO. Push or call? A few years ago a short stacked flat from a reg was often AA. Can I get away with flatting? How deep do I need to be to flat or 3-bet/call? Obviously, I am never reshoving with this hand unless anything else looks too strong.
