I haven't read the replies to this thread yet, but I would only care about keeping the bubble alive if like, you had 2000 fewer chips and the 770 guy had those 2000 chips. Then there would be a lot of chips to pick up by exploiting the bubble.

But with the stacks as given in the OP, you have almost 2/3 of the chips in play already. You are basically guaranteed at least second. Just play to maximize cEV.
