50NL: 2 overpair hands

[MikeyObviously]

limit player, new to NL. I'm 15k hands in, up 4 ptbb/100, and play at about 17/11/2.

Two very standard spots that still confuse me. I feel like going by stack to pot ratios that I am committed, but it also looks like I am very likely beaten.

I feel like both of these hands...I should be folding to flop raises. Oh, and I should note I have the guy in the AA hand at about 12/5 and no reads on the other.
