No reads on villian, hes 20/13.3/11 over 75 hands. Running bad and tilting some so im questioning my play. Do I always felt AA here?

This spot is a great deal +EV. My money is going in here every time with a smile.

Stack to pot ratio on the flop is about 3.25. I'm putting it in with an overpair here.
