Hands late in MTT with huge blinds

[ukpokerplayer]

This situation comes up pretty much every big MTT that you near the end of. Lets say your down to 4-5 handed, you all have slightly less than 200k in chips, blinds at 10k, 20k.

If you pick up a decent hand on the button (say any pocket pair, A9+), what is the best move.

Calling is obviously bad, and any raise seems to pretty much committ you if someone comes over the top. So in this situatioon do you just push?

Last night for example, I have about 180k, blinds 10k, 20k 4 handed I pick up 77 on the button. both blinds have similar stakcs to me. what is the best play here?
