So this spot is really twisting my mind and I just can't figure out if my play on the turn is a spew so I'm asking you guys to help me out. Guy who 3bets BTN is big player in never bluff team and extreme nit so I think pre I have easy flat with UTG still to act behind. I have only 44 hands on the UTG and he seems pretty reggy but sample is v small obv, playing 23/20. When he donks the flop I'd assume (maybe I'm completly wrong) the only FD that makes sense for him to have is KQc and then he has TT QQ AT AQ and AK(?) for value. In the hand I thought that calling turn is pretty akward and looking at his betsize I assumed he might still bet sets like this but once again, I'm very unsure about that. So judging by my assumptions that he only has 1 combo of flushes on the turn and lots of sets/2pair I decided to deny his equity by jamming and maybe if ther'e a slight chance he folds AK then it should print money but I really have no clue on what really the best play on the turn is. Sorry for my english, any help is greatly appreciated :)
