, marked by letters a–l (letter j is not used), and 11 numbered (which bend 60° at file f). Ranks 1–6 each contain 11 cells, rank 7 (filled with black pawns in the initial setup) has 9 cells, rank 8 has 7, and so on. Rank 11 contains exactly one cell: f11. The moves of the pieces are as follows: The rook may move any number of cells orthogonally, traveling through cell edges. The bishop may move any number of cells diagonally, traveling through cell vertices. The queen may move any number of cells orthogonally or diagonally. The king may move one cell orthogonally or diagonally. There is no castling. The knight may move two cells orthogonally in one direction and then one cell orthogonally at a 60° angle, jumping over intervening pieces. Equivalently, the knight may move to any nearest cell not on an orthogonal or diagonal line on which it stands. The pawn may move one vacant cell vertically forward. If it stands on its starting cell or on the starting cell of any other pawn of its color, then it is also allowed to move two vacant cells vertically forward. It may capture one cell orthogonally forward at a 60° angle to the vertical, including capturing en passant. (This capturing move is not diagonal, unlike in orthodox chess.) It is promoted when it reaches the end of any file. In the pawn diagram, if the pawn on e4 were to capture a black piece on f5, then the pawn would retain the option to move to f7. If the black pawn on c7 in the diagram moves to c5 in a single move, the white pawn on b5 can capture it en passant: bxc6. Stalemate is not a draw in Gliński's chess, but it is still counted as less than checkmate: in tournament games, the player who delivers stalemate earns point, and the stalemated player (the player without a legal move) receives point. A numeric (or international) notation exists. Every detail is exactly as in ICCF numeric notation except that there is no castling. Observations Unlike in orthodox chess, a king and two knights can mate a king. A knight can triangulate. A player's three bishops, relegated to different colours, can never defend each other. In the initial setup, the white pawn on f5 cannot make a double step to f7, which is occupied by a black
