Folding aces on the flop?

[deaders]

This hand just happened: Prima NL20 6 max, villain and I both have about $25. I get AA in mp and open for 4x BB. Called by loose, weak button and good TAG big blind.

Flop comes KKx, BB checks, I bet the pot ($3), button folds, BB minraises. I have played against the guy a fair bit and he seems pretty good and doesnt try anything tricky, can I do anything here but fold?
