Just a comment on Sam's 31 short-range pieces comment:
I noticed he mentioned the lion as worth 2 queens. Perhaps, on a very crowded small space, but I don't see how this can be on a large open board.
In my game Asylum Chess, the piece Insane Ninja Knight has the moves of a lion (and double capture too).I say its worth slightly less than a queen in this game on an open board.
I don't see any clear description of the lion except in Cho Shogi game (and they are some differences).
(In fact, I initially thought that the ninja knight was never seen before in any form!)
I have yet to see the Lion used in any other game.
Perhaps, it is assumed that a jumping piece should not be too powerful or the gameplay would not be balanced?
