we might beat random

Bring it on! Just to elaborate, in an iterated 1v1, a defectbot will reliably beat a randombot (4 to 1 if the randombot is unweighted). Or rather, any bot which detects a randombot and then always defects.

However, it's not even necessary to beat the few randombots in a 1v1 to win the tournament, it is sufficient to beat a majority of other bots (including some cooperatebots for easy wins) to get ahead of the pack enough so that the results against the randombots don't matter.
