Playing AK OOP in Reraised Pots

[bobbyi]

This is a basic situation and I wanted to do a checkup here. The button seems pretty aggressive; his pfr is about 25 and he has been betting and raising a fair amount postflop, but I haven't seen him play any really big pots yet.

I think I have to reraise preflop because if I just call, I am going to be playing AK OOP in a multiway which doesn't sound pleasant and because the guy raises enough hands behind two loose limpers that I have a good shot of taking it down immediately.

If you agree with that, I am mainly wondering how much to bet on the flop. I don't like betting full pot because then a push is just a min-raise and it sucks to have to fold here getting 4:1, so I decided to bet less.
