I would doubt that, because in Pritchard's description of Maximummer
Chess, he specifically explains that it is geometrical length; no such
mention is made for Proximity Chess.
Also, I would think that anything except King-move distance would make for
a worse game, because it would only further cut down a player's (already
few) options.
