AKs did i do the right thing?

[Crispy]

Blinds are 100/200. UTG makes it 600 so i put him on a large hand. I look down at my AKs spades. I decide that I should limit the field and I reraise all in. Me and the UTG are about even in chips, around 4000. ONe more caller mid position calls all in. Flop comes Qhigh and rags no spades. UTG has KK, MP guy has JJ. Im out of the tourny. Did i make the right play?

If by "large hand" you mean KK or AA, pushing is obviously not the best move. I mean, you said he has a big hand, why would you want to push against it?
