I agree with everyone else after the flop.

I actually do think the re-raise is a little on the passive side with 1 caller already, but it depends a little also on stack-depth. I'd probably usually make it $130, which also (at least in the game I play) is more typical of an AK re-raise.

Once you've re-raised at all, unless there's like at least $1,500+ in stack depth, it's very hard to get away from AA. So, I think it's important to deny them odds to set. If the bet is bigger, ok, I'll get stacked if they hit, but they're still losing money in the long run.

You got in 13% of your stack in preflop with AA and its heads up. Can't ask for much more. Get your money in here every time heret. He could have AA, AK but there are still more combinations of AK (6), than, KK (3). You also played it passively so his range is even wider here.
