KK against flop smooth call OOP

No reads on Villian, I just sat at the table

.05/.1 NLHE

Hero is deep stacked ($22) and covers Villian ($9)

UTG+1 limps for .10, Hero with K [img]/images/graemlins/diamond.gif[/img] K [img]/images/graemlins/spade.gif[/img] raises to .50 in MP, Villian on the button calls, UTG + 1 calls

FLOP J 3 4 r pot ~ 2

UTG + 1 checks, Hero bets $2, UTG + 1 folds, Villian thinks and calls

Turn 5 (no two to flush)

Hero??? Am I up against a set here, top pair, or Aces?
