In the paper, David Wu hypothesized one other ingredient: the stones involved have to form a circle rather than a tree (that is, excluding races that involve the edge of the board). I don’t think I buy his proposed mechanism but it does seem to be true that the bait group has to be floating in order for the exploit to work.
