Pretty sure this is a spot i play bad so thought i'd finally paste a hand. So blinds are getting big and two of us are fighting not to bubble. If i fold this hand i will be left with ~1200 chips and no FE vs 6500, 3400 and 2700.

If i spite call here and i lose im basically dead, but if i double i'm now level with the 2nd place stack and since i play better than them at pushbot - in pretty good shape.

So what do people call with here? What do people fold?

Fwiw i know nothing about him, hes a random to me but i would imagine he is pushing a reasonable range here.
