raise mediocre hand and nail the flop

[Crusher19]

when the hand was all said and done the 3 bettor showed AQ and the bb won the pot with KK. with the bb not capping pre flop it kind of messed up my read on the hand. i thought the 3 bettor was more likely to have AA or KK and the bb i was thinking more of AQ or KQ. either way with all the action on the turn 3 ways i find it hard to believe that im going win the pot with running pair to counterfeit my hand vs overpair and was wondering if anyone thought the river was closer to a check fold or check call ever.
