The comments about the pieces in Supremo Superchess have me thinking about
cannon pieces generally and how they might be used in CV's. Rook+Pao
(never mind Queen+Leo) are much too powerful for an otherwise FIDE-like
game. But imagine these power pieces up against say the Reaper or Combine
from Tripinch Chess. Sounds more interesting?

Also consider divergent cannon pieces: Rook+Vao and Bishop+Pao. For these
I would use the Korean cannon moves--the RpB must leap to move diagonally
as well as to capture. These should be interesting pieces in a
variant--starting off at about Cardinal value, declining to little more
than Rook and Bishop in the endgame. Thes would be interesting with other
pieces that gain power in the endgame.

Any thoughts about a cannon Nightrider?  (It needs a big board!)
