KTo UTG, 4.5BB stack with 7 left in a step 5 - push or fold?

[Marnixvdb]

ok,

I think it's a close call between fold and push, so I'd like to hear some opinions: in a Party step5 STT with 7 players left, blinds at 100/200 with 5 hands to go at this level, you get dealt KTo UTG. You have 920 chips and the table has seen some action in this and the previous blind level, having been pretty tight the levels before. You have not played a significant hand until last hand where you pushed TT to pick up the blinds.

Do you push in this spot?

And if not, what hand minimum would you push here?

thanks,

Marnix
