I would bet flop 100% because BB is not calling (flop missed like 90% of his calling range pf) and if UTG nit calls, you're DONE with the hand. By doing this, you fold out everything UTG nit raised with that you beat, but this is a very good thing since you won't pay him off later in the hand thinking you have the best hand here IN CASE he does have AK/AA/KK here.

I would bet half-pot on the flop, it's the perfect amount. In addition, I would bet on the flop with any two cards. UTG calling here and giving you more action essentially turn your hand into any two.
