i dont think we can knock his slow play here as it got the perfect desired result, and he got all of his money in as a 7-1 favorite. Can't think of a much better situation to be in.
You are right sometimes you have to slow play AA or KK or mix up your game, and there was nothing wrong with your play. You just got unlucky. Most of the time you want to raise, but this time the limp was fine.
good play, bad results...
