1/2 Crappy river decision deep w/ AA

[McRoNiX]

Had villain as something like 22/15 over 50 hands with no real history.
Shoulda 3bet pf bigger as we're deepish I know. Thought his turn check behind was a little strange. At the time I bet riv because I thought checking would be losing value from weaker hands but looking back, I guess the only weaker hand which might call are 88 99 TT, maybe QQ or KK? Is this river a c/c. As played hero....?
