Try playing AK like you play aces. That means reraising preflop and betting any flop that comes out.

That also means that you cannot push all-in with your aces because you don't want to push with your AK too. Be consistent about this and people will believe that all of your AK's are big pocket pairs.

Just be careful though. If you got a lot of callers or if the board is great for drawing hands then play carefully. Your cont bets will usually fail in these situations.

I will usually shut it down if I get called on the flop. I don't want to hang myself and a REAL bet on the turn will cost too much.
