It's a tricky hand as well , If I haven't 3 bet with that hand and I am OOP I check the flop and muck to a cbet,Unless my opponent cbet with his whole range there. If I have opened with AK and I am IP and the player before me checks , I make a cbet around 35% of the pot. I can still hit my A or my K on the turn. If i don't hit the turn either then most of the times I give up.
When I have around 12bbs I shove it in MTTs. Don't take as granted that with 12bbs you always shove AK. It depends on many factors. I told you for a specific situation. gl
