Given preflop his most likely hands are stuff like 1010-QQ, AK, AQ then AA-KK

Given the flop action his range is stuff like JJ-AA, of which there 3-JJ, 6-QQ, 3-KK, 3-AA and maybe 1.5-99 given he might fold that preflop. I think flush draws will generally be jammed on the flop and can be discounted heavily. Also maybe tt-calls 1/2 the time for 3 combos.

Now the turn is pretty key in how he would play his set range verse his overpair range. If he checks back his whole range the river shove looks bad.

He is always calling with his sets and AA which make up 8.5 combos 3-JJ, 3-AA, 1-KK 1.5-99. That leaves 6 combos of QQ.

C-folding may be the best play on the river.
