Semedo (Latin: Semedo) — a variant of chess, presumably invented by Álvaro Semedo.

Some chess historians dispute the existence of such chess in general. Supposedly invented by a Jesuit missionary in China, Álvaro Semedo. Subsequently, other Catholic missionaries in China reported a special Chinese chess called "semedo". A description of this game in latin is given in a book published in 1694 in England.^[1][2]
