[DpR]

Your river fold doesnt make any sense given your preflop action. While I agree that you are usually behind after the turn c/r, KQ, KJ, a tricky 88 are possible (in decending order or likelyhood) enough to make the river call.

I also never call a rasier with KQo preflop. IMO, that is a really bad hand in this situation. I would fold preflop, but call the river.
