This game is described in D. B. Pritchard's Encyclopedia of Chess Variants, where it is attributed to a J. Boyer in the 1950s. Pritchard cites a supplement to Jeux d'Echecs Non-orthodox by Boyer and Nouveaux Jeux d'Echecs Non-orthodoxes. The game is so-called because of the Leo piece, which is named for Leo the Lion.
The setup is the same as for Chess except that it replaces Rooks with Cannons, Bishops with Vaos, and Queens with Leos.
The Cannon moves as a Rook except that it must hop over an intervening piece to capture.
The Knight moves as it does in Chess.
The Vao moves as a Bishop except that it must hop over an intervening piece to capture.
The Leo moves as a Queen except that it must hop over an intervening piece to capture.
The King moves as it does in Chess. It may presumably castle with the Cannons.
RulesThe game is played like Chess except for the replacement of the Rooks, Bishops and Queens with Cannons, Vaos, and Bishops. Kings can castle with Cannons, and Pawns promote to regular Chess pieces.
