I've played a lot with him @ 2/4 and 3/6 and I'd certainly be getting this in preflop vs him. Whether or not he plays much different at 100nl I'm not sure but how do you expect to stack AK by flatting pre. You lose on A high boards and you have 2 of the cards that he stacks himself on. I don't expect him to fold AK or QQ unless op is playing real snug.
