11世紀までに遡る、現代チェスの直接の祖先。キングとヴェジール（クイーンの祖）の位置が現代チェスとは逆で、キングがd筋、ヴェジールがe筋に立つ。ヴェジールは斜め1マスのみ、エレファント（ビショップの祖）は斜めにちょうど2マス跳躍（間の駒を飛び越える）と、可動域は現代の駒よりずっと狭い。ポーンは初手も1マスのみでアンパッサンはなく、昇格はヴェジールにのみ可能。キャスリングはない。勝利条件はチェックメイトに加え、相手をキング1体だけに追い込む「裸の王」（ただし自分も同時に裸の王になった場合は引き分け）。ステイルメイトは現代チェスと違い、動かせなくなった側の敗北となる。
The direct ancestor of modern chess, dating back to at least the 11th century. The King and Vezir (predecessor of the Queen) sit on opposite files compared to modern chess — the King on the d-file, the Vezir on the e-file. The Vezir moves only one square diagonally, and the Elephant (predecessor of the Bishop) leaps exactly two squares diagonally, jumping over anything in between — both far more limited than their modern counterparts. Pawns advance only one square even on their first move, there's no en passant, and they may promote only to a Vezir. There's no castling. Besides checkmate, a player also wins by reducing the opponent to a bare king with no other pieces (unless this happens to both sides on the same move, which is a draw). Unlike modern chess, stalemate is a loss for the player with no legal move, not a draw.
