I'm not sure that I would have pushed all in on the first hand because of my limited stack. I think that you should have protected your hand on the flop with a larger raise, rather than trying to "sandbag" aces, which is never a good idea, especially in a NL game with a limited stack. Personally, I would have raised on the flop all in, rather than give him a chance to get lucky on the turn or river with a crazy draw. Also, this eliminates the confusion that he creates on later rounds because you would know where he stands.
