Opponent is a decent reg in my opinion, although he opens 20% UTG after 1.3k hands, thats why I decided to 3bet plus I have position and we are insanely deep. After his 3bet, given the stack sizes and my playability I think calling is mandatory, right?

On the flop I think thats a standard call nothing to talk about. Or would you play differently?

On the turn, probably gin card for me. I got two pair and a flushdraw so I decided to bet big. Looking at this now I think I should bet smaller to get called by weaker hands maybe? Once he raised I was really confused, because I dont think he has that many QQ in his 4betting range plus I block top two sets pretty well and I dont block As. But I dont think that he would check raise turn with AA with a flushdraw 800bb deep. I decided to fold, because it looks like some kind of a set or big wrap + nut flushdraw that I dont block.
Either way against this range: (QQ,(AKJ:(Ass),TT):5% I have 34% which is not enough for stackoff. What do you think about his range on the turn? Could it be wider?
