ITM final three, but everyone is fairly equally short stacked

[SumZero]

Typical 50/30/20 split in a turbo like fashion.

Villian1 is at seat 1 with 259720.
Hero is at seat 2 with 206940.
Villian2 is at seat 3 with 169340.
The button is at seat 1.

Villian1 posts ante (2000).
Hero posts ante (2000).
Villian2 posts ante (2000).
Villian2 posts the small blind of 10000.
Villian1 posts the big blind of 20000.

So there is 36,000 in the pot each hand. We have an M of 5.7, chip leader is 7.2, and short stack is 4.7. We are about half way through the level so blinds go up in another 2-3 minutes. What fraction of hands do you push with from the button in this situation?
