As a generally rule, I always raise a modest amount with AK to discourage any limpers behind me. I prefer HtoH or 3-way action with these hands. I dont know alot of positions where I would limp/raise. Maybe if there was a lot of other limpers, the raiser was to my immediate right, and I knew they were weak. Here I might push all-in to get HtoH action or maybe pick-up some dead money. If I call, theres a good chance there will be a multi-way pot and my AK wont be worth as much.
