resteal with air here? 500k hand

[schwza]

i just got moved to a new table a couple hands ago. there's been talk on the boards about "how much easier poker is when you resteal with nothing at 10-12x." is this a spot for that?

don't have the hand history, but i remember it all:

25/50 i have 56o in the BB
CO (4.3k) raises to 200
i have 680 after posting. push or fold?

SB and button are around 2k.

if i push villain is getting 1.8:1.
