What is your position? What was the action before you? What are the blinds? What is your table image?
All of that should be answered first before I can give you my thoughts on what to do?
In general, AK is way overrated in todays game, especially online. It isn't like today's players are laying down that pair of 77's to a decent raise like the old days. I'll generally raise first in, I'll lay it down to large bets or large reraises. It isn't a made hand.
