Raise more pre-flop and lead like pretty much all those flops (basically agreeing with previous advice).

Not to be harsh, but I think you misplayed every one of those AA hands.

AA is the nuts preflop, but weakens considerably after 5 cards are out.

Your play is backwards. You bet softly (while still declaring big pp with a reraise) but offer good implied odds by stacking off lightly.

1. Play them faster preflop. If you're out of positon (blinds etc) consider raising bigger than pot.
(Make sure you balance your range by doing the same thing with hands other than AA,KK. Might not be applicable at these stakes)
2. Stop checking flops with AA. You ruin the credibility of your cbets if you check your big hands.

3. Stop playing AA like its an unbeatable hand after the flop. If you're crazy aggro on a 6max table then it's ok. But when playing nine handed tables, don't be afraid to release them on dry and/or dangerous flops.

Good luck.
