Aks call or fold all in bet

Villain is played only few hands. No reads.

Pacificpoker 5-handed 10pl.

I pickup AKs in BigBlind. Villain minraise, 2 people call before me. I raise pot. Sb and Villain calls.

Flop comes K Q 6 all same suit. Sb checks, I bet pot and Villain push. Pot is now 15$ and its 5$ more to call. Whats is right play here?
