I waffled here between just call and shove, but looking at the hand and the way that the villain played it, I just have a hard time seeing him show up with a better 9 here/set.

I shove the river here, I think hand is underrepped to the villain, and the only line I can see him taking like this is Kxcc. I think villain probably looks you up with his K here to. 22/33 raise the turn, and I think most 9's do also. CO never open limps AK/kk, and pretty rare to open limp a small PP.
