AK hand

[usi34]

3/6NL on Bodog, just sat down, dont' have any reads really.
No hand histories, sry.

Here is dealt AKo in BB with $600. Folded to MP2 who makes it 24. He has hero Covered. 2 others in LP call (stacks not important).
Back around to hero. I just really hate my spot here. How many of you re-raise PF in this hand. How many just smooth call. Well I call, while not feeling very good about my spot.

Action to Hero. How many people lead this flop. Im just lost here, I dont know the correct play. Well I check and the original raiser makes it 75.
Folded around to hero.
