This game is a favorite of its inventor.

Kuuzen Dai Shogi

This game was invented by Eric Silverman.

During an email conversation between myself and Eric about reviving Suzumu Shogi and Mitsugumi Shogi, Eric mentioned his work-in-progress 15x15 Shogi variants, one of which was Kuuzen Dai Shogi, which is basically Dai Shogi but with different promotions. I found the variant most interesting, and decided to post it to the Chess Variant Pages.


The setup for Kuuzen Dai Shogi is the same as in Dai Shogi. An interactive diagram has been provided (The Javascript source code was written by H. G. Muller) to make it easier to understand how each piece moves. The Mnemonic piece directory uses H. G. Muller's Mnemonic pieces.
