Micro shogi

Microshogi (五分摩訶将棋 gofun maka shōgi "5-minute (scarlet) poppy chess") is a modern variant of shogi (Japanese chess), with very different rules for promotion, and demotion. Kerry Handscomb of NOST gave it this English name. Although not confirmed, he credits its invention to the late Oyama Yasuharu, one of the most famous professional shogi players in history. In the mid-1980s, Handscomb was gifted a set custom made by a Japanese craftsman. Therefore, the game must have been invented before this time.
