Looks like MP1 has a monster and doesn't want you to fold. Nevertheless, once you've made such a big raise pf, you are pretty much going to call that bet.

I think your preflop raise was the mistake in this hand. I know you were following some formula, but you should think deeper about the purpose of that formula. With AK, you prefer it to be heads-up on the flop. You should bet the amount that will get some decent hands that you dominate to come along with you. 2000 ain't it, not when the blinds are this large. 1200 would have been sufficient, and would have allowed you more choices pf and on the flop.
