I like your strategy. It's definitely what I would do... He ran into JJ, but I would imagine he would have done the same thing w/ AQ, AJ, and maybe even AT. It would be a nicer strategy for you if you had a bigger pair, but I think AKs is good enough.

I'm not sure how easy it would be to just 'move to his left'... I doubt the guy already so positioned would appreciate it much.
