Capablanca Chess

From Wikipedia: Capablanca Chess is a chess variant played on a 10x8 board. The game is named after its inventor, the former world chess champion, José Raúl Capablanca. Capablanca thought that chess would be played out in a few decades, that games between chess grandmasters would always end in a draw. This danger of "draw death" was a main motivation for him to create a more complex and rich version of chess.

Besides the usual set of chess pieces, each player has additionally two new pieces with corresponding pawns: Chancellor: a chancellor combines the moves of a Rook or a Knight; Archbishop: an archbishop combines moves of a Bishop and a Knight.

The new pieces have properties that enrich the game. For example, the archbishop can checkmate a bare king by itself (king in a corner, archbishop placed diagonally with one square in between). Capablanca thought that adding these two powerful pieces would reduce the likelihood of a draw and make the game itself more interesting.
