I just heard Lederer say this the other night and is what I was thinking about your situation:

NO good act will go unpunished...

The AA though powerfull preflop are just two cards. If you had sixes and your nemisis had the same over pair even AK it's essentially a coinflip (54 46). With QTo you had him 4:1 and guess what you played it as a coin flip... Though this guy was either crazy or balzy, it was plain by his 10.00 (20BB) that he did not respect your (6BB) 3.00 bet. But even after the flop you are 4:1 favorite. Even though I would be thinking set of T's at that point. However you EV is roughly +$66.70 for the cost of a call. 66.70 = (.8*72.75) - (.2*-44.50) - But he sucked out on you, S**T happens. The only thing may have been to re-raise if you really believed you had the nuts; after all you made a 6BB preflop he then would have to put you on Q's even though he knows for certainty where two allready are. Thus putting the preasure on him and increasing you EV at the same time.

You did the right thing and got punished for it - for now.
