Tough spot against solid nit [at the beginning of the session he opened UTG, got 3bet from very Lag player from MP, he 4bet, and the Lag insta-folded AKo face up, and the nit showed AA - 100bb deep- A few hands after I opened from the CO 150bb deep with JTs he 3bet, and I called. The board came A69 with a BDFD, the flop checked behind by him. The turn was T, I checked call, on a river A, he bet strong with Quads. He doesn't value bet thinly at all].

Stacks 260bb eff, I open QQ to 3bb from the co, nit 3bets from the button. His range is strong and [76s not in his range there], I decide to call oop. The flop came QTT, I checked, he bet 13bb [into 19.5bb pot] I called. The turn was 4s putting a FD on the board, I cheked and he bet 31bb [into 46bb~ pot] I called planning on c/s the river. The river came As. I insta check-shoved river after he bet 46bb into 108bb pot]. He showed AA for a better full house. Is this shove to thin against this type of player? Does he ever have a made Flush on the river? What would u do? Well I know he could call me with worse [No one folds anything good to me...] but does he ever have a worse hand there?

Thx
