My 2cents:

AA: I think it was a bit overplayed. The preflop looks ok. It looks like your intent is to bet the pot on the flop and turn bet. However, by the turn.. you already pot commited and wont be able to fold in any situation. If your mindset with AA is to risk all your chips HtoH once the flop hits, I think thats a bit aggressive. I normally dont think of the big bets unless I have 2pair, trips, etc.. With these hands I dont mind going all-in. Personally, I would of bet 1/3 -1/2 the pot on the flop, and something similiar on the turn. It gives you a little more room to decide if an all-in bet occurs on the turn

The question would be: What would slow you down or what situations would allow you to get away from the hand? Its hard to get away from any hand once your pot commited...

2hand: Much better hand than AA if another diamond doesnt drop can be played a bit more aggressively. I wouldnt mind going all-in in this situation. I might have check/raise the turn...
