what should i have done??

Since AK is a drawing hand it is hard to say.

It all depends on player history. If this player is a rare raiser and comes out with a big raise I would put him on A-A or K-K myself.

You really want to hit your Ace only. Then you can find out with aggressive betting if he is holding A-A or K-K and maybe Q-Q. If a King hits you could end up in a heap of trouble.

But thats just me.
