a WTF? limp min reraise

[billyjex]

this hand had me all sorts of confused..

Party $30 rebuy. We're down to about 100 out of 360. Avg stack is around 10k, I have 19k and villian has about 17k. Villian has limped multiple times, but other than that I have not noticed what kind of hands he has showdown or his postflop play. I blame ADD.

My image is solid TAG. I have only shown down good, winning hands.

Blinds are 200/400.

Villian limps UTG+2. Folded to me on the CO w/ AcJc and I raise to 1600.

Villian minraises me to 2800. I really don't know if this means AA or KK or if he's just being donkish.

I call, ready to give up on the hand if I miss..

Flop is K66, two diamonds. No clubs. Villian checks.

Do I bet? Do I just check and give up on the hand? I really could not put villian on a hand.
