3/6NL: QQ, not sure where I am on the river

[Marwan]

I would look him up, this is pretty weird.. I'd think a nit with those stats and AF would start betting better hands on the turn.. He's very unlikely to have a K with how the PF action went down.. his line preflop is also pretty weird, cold calling a raise and then calling your re-raise... my best guess would be some suited connector or mid pair that called initial raise PF and then decided he had "odds" to set-mine/try to flop big b/c you 3-bet relatively small (<pot-size at least)

if we assume he 3-bets AK/JJ/KK PF and folds baby pairs (or at least bets a set before the river), then all you're really behind is a rivered set with the 99.
