kk with Axx Flop against maniac

[GittyUP]

Villain is quite loose and I 3 bet him the last 3 times because i was on a rush. He is 50/28/2/5 over 50 hands. What to do on flop with this bet?? And river? Looks like a bluff?

Maniac isn't going to check turn with an ace. He's gonna spew. I think checking behind turn is *maybe* good, but then call river.
