Interesting/Fun Hypothetical Situation

[Steve]

You're in an online MTT. Midway through the tourney, still far from the money. You have 15,000 chips, blinds 500/1000, so your M is 10. The player to left has exactly 15,000 chips too.

Here's the hypothetical part. This opponent says, "Lets flip a coin, and the winner gets all the other player's chips" (imagine for a moment that's legal). Do you:

1) Accept his offer, because the blinds are starting to get big and this is a 50% chance to double up and get up to an M of 20 and be in better shape?

2) Decline his offer because you believe you can get your chips in with better odds on some future hand.
