$50 PP NLHE SNG. 3 Left, blinds are 100-200.

Hero SB (700)
BB (8975)
MP (325)

I get AK in SB, MP folds - what should I do. I was really torn weather to call, raise or fold. At this point, MP and I are basically playing for 2nd place and most of his chips will be in the pot blind in the next 2 hands, but do you lay down AK in this spot? I already had $100 in the pot with $600 left if I fold. If MP wins his all in on his blind, we are back to even. If I double up, I virtually assure myself 2nd, but risk going out 3rd. What would you do here? Thanks, as always.
