And here's the 2nd hand:

Only had about 20 hands on villain. He's stats were something like 33/30/2 over those hands. No specific history until then.
I've been 3betting a bit but nothing crazy.
Here villain's range on the river is 88-JJ (I would expect QQ+ to 4bet most of the time), 22, A8,AT,JT, AQ/KQ/QJ, 9T,89,67, suited/gapers clubs (but cannot have Axc as I have the Ac).
My range is quite polarized (even though on the TURN I might not always 2barril with QQ-AA): some AA, 99/88/22, 98s, JT, QT, KT, AT, some overs and air.
Again on the river we have air, by checking we will only win if villain has something like KcJc and he check RIVER. He might push the busted draw though.

Any thoughts? It seems to me his range is most likely pretty strong, but the 9 might make him fold Tx or maybe JJ as well to a push?
