Normally, I never even really consider trapping with AA/KK, not in a single raised pot anyhow. This seemed like it might be a really good spot though, because obviously it looks super strong 3b'ing the UTG opener anyway, and UTG here is going to be worried that if he flats a 3bet the SB will ship. UTG also might know that I know that, so it turns my hand even more face up if I 3bet.

UTG is reggy, 25/22, 9% 3bet, positionally aware and tight utg.
SB is 21/9 over 60 hands, 4% 3bet, looks like a somewhat tight fish.

Thoughts?
