tough spot w/ AA fairly deep

[stunna954]

I've been experimenting playing more lag (28/25) then I have in the past but I'm having difficulty with big overpairs.

Heres a spot where I'm really am having a difficult time. Villain in this hand is playing 14/10/2, he seems to be a thinking player and I've 3bet him a couple of times before.
