This is a pretty standard steal. If it works even half of the time it is profitable.

One major thing working against you though is that your limp/call preflop doesn't look much like an ace. If you're unknown to MP2 he may still give you credit, but if you're not careful you may find yourself getting looked up by better pocket pairs. I've certainly checked behind with JJ/KK on flops like that with the intention of calling (or sometimes even raising) a turn bet. I figure I'll lose a bet to Ax by betting the flop, but at least if I check I'll sometimes win an extra bet if my hand is good.

This btw is also an excellent example of how limp/calling with AK can be very profitable in EP. Now instead of just having to consider whether you've hit a set on this hand, they must also consider whether you hold AK. The wider your hand range here, the more chance they have to make a mistake.
