I don't agree that the villain is overplaying his aces. I think the villain's play is fine. I'd bet a little bit more, but it is easy to call the flop check-raise.

You have to distinguish playing shorthanded with short stacks with playing in a full game with deep stacks. The probability that one or two people outflop AA just isn't so high, and AA has a ton of outs against 2-pair.
