I've attached a picture showing a relatively simple way to run a single chain for 3 wheels and 2 motors.

There are two ways that a chain can "break" in a match:
1) the rare, unlikely way where chain tension limit is exceeded
2) the more frequent and likely way is for a master link clip disengaging & falling off. Then, soon after, the clip side link plate slides off the pins, leading to the rest of the link popping out and effectively "breaking" the chain..
Either way, with a single chain per side, this essentially kills your bot.
