Lay down trip aces in blind battle?

[Parlay Slow]

Villain in this hand is 'yamaha r 1'. I don't play much Stars 2/4, so I don't really have a read. Over like 30 hands his stats are borderline nitty. Usually I have a better plan for the flop, but this guy wasn't a known flop CB raiser. I have a lot of trouble laying down a hand this big in a blind battle, but it seems like it would be the worst bluff ever. It seems like he WANTS me to have the hand I have.

Who folds? Who says f*ck it, trip aces, and calls?
