If you think UTG as AA and MP3 has Ax, then neither has good odds to improve so your odds may be a bit better than 3.8 to 1. You'd be way ahead of MP3 based on this read, with a chance sucking out on UTG and taking the whole pot.

If you were heads up with UTG and he put you all in I think you could make this laydown and feel good based on your read, but you had pretty good odds to call here if you felt a read of AA and Ax were strong.
