i hate these spots, fold the AA?!?!

[LAgambol]

10/20 NL
Villain is LAGish good player, he is more of a 'feel' and unpredictable player
Hero has been playing very LAG.
Effective stacks: 4.5K

Hero has AA in BB
1 limp, villian makes it 120 in MP, CO calls, SB calls, hero makes it 500, villain calls, the rest folds

Flop:
Q J 7
Hero bets 1000, villain raises to 2800, Hero...
