This is probably how I play it OOP. Always cap AK pre-flop. That is fine.
There is a good discussion in the "Big Aces, Big Blinds" thread about this kind of thing.
The continuation bet with 2 opponents seems good, although I guess the re-raise from the early limper is suspicious. Myself, I keep betting with one opponent left as you did, but I am curious what others will say, as this is a part of my game I need to focus on. Often times, if you keep betting into one opponent like that on a low flop, it is just a passive
poker player with something as good as QQ who is afraid of aces or kings. The question is how often?
