Английская Википедия:Chesquerque
Chesquerque is a chess variant invented by George R. Dekle Sr. in 1986.Шаблон:SfnpШаблон:Sfnp The game is played on a board composed of four Alquerque boards combined into a square. Like Alquerque, pieces are positioned on points of intersection and make their moves along marked lines (similarly to xiangqi); as such, the board comprises a 9×9 grid with 81 positions (points) that pieces can move to.
Chesquerque was included in World Game Review No. 10 edited by Michael Keller.[1]
Game rules
The dimensions of the board are 9 rows by 9 columns. All the standard chess pieces are present, plus one additional pawn and one archbishop fairy piece per side. The pieces move in ways specially adapted to the Alquerque-gridded board; these moves differ slightly from those in regular chess.[2]
The starting setup is shown above. Like in standard chess, White moves first and the objective of the game is to checkmate the opponent's king. Other standard chess conventions also apply.
Piece moves
Each chesquerque piece has two different sets of possible valid moves, depending on whether said piece is standing on a point that has Шаблон:Em diagonal connections ("with diagonals") or one that has Шаблон:Em diagonal connections ("without diagonals"). In general pieces cannot move diagonally from points without diagonal markings.

- A rook can move orthogonally any number of points in a straight line, as in standard chess. On a point with diagonals, though, a rook can also move one step diagonally.Шаблон:Efn
- A bishop, on a point with diagonals, can move diagonally any number of points in a straight line. A bishop can also move one step orthogonally (on any point).Шаблон:Efn
- The queen combines the powers of a chesquerque rook and a chesquerque bishop: i.e. it can move any number of points in a straight line, in any available direction along marked lines.
- The king moves one step as a chesquerque queen: i.e. it can move one step in any direction along marked lines.
- In castling moves, the king always slides Шаблон:Em points' distance (whether castling Шаблон:Chessgloss or "Шаблон:Chessgloss"); the corresponding rook moves two squares in the opposite direction.
- A knight can move in a similar way to a regular chess knight (described below), but unlike standard chess, a chesquerque knight may not jump over any pieces standing in the way:
- On a point without diagonals, a knight moves in the following pattern: one step orthogonally (in any direction), Шаблон:Em one step diagonally outward.Шаблон:Efn
- On a point with diagonals, a knight moves in the following pattern: one step diagonally (in any direction), Шаблон:Em one step orthogonally outward.Шаблон:Efn
- The archbishop combines the powers of a chesquerque bishop and a chesquerque knight. (Note that when making a knight's move, the archbishop still cannot jump over any piece that stands on an adjacent point; however, an Шаблон:Em piece on such a point Шаблон:Em be captured by a bishop's move.)
- A pawn has two types of moves:
- On a point with diagonals, a pawn moves (without capturing) one step straight forward, and captures one step diagonally forward.Шаблон:Efn
- On a point without diagonals, a pawn moves Шаблон:Em captures one step forward.Шаблон:Efn
- As in standard chess, all pawns may optionally advance two steps straight forward on their first move (without capturing). En passant captures are also possible (but only against pawns that start on points without diagonals). Pawns are promoted at the last Шаблон:Chessgloss, and may be promoted to an archbishop as well.
