10NL, AK facing turn min-raise

Villain is 30/20/2 over 54 hands with a 3-bet of 10%, 2 out of 20 opportunities.

When I bet the turn big, I'm committed but the small turn raise is weird. I'm not sure what he can have, but I have AK on an A-high flop in a 3-bet pot. Go with it? Or is this a Baluga situation?
