What is "chesquerque"

Chesquerque is a chess variant invented by George R. Dekle, Sr. in 1986. The game is played on a board equaling four Alquerque boards combined, and like Alquerque, pieces move along marked lines (9×9) to the points of intersection (81 points). 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.

Chesquerque was included in World Game Review No. 10 edited by Michael Keller.
