Description

A chess variant played on a board made of hexagons invented by Isaak Grigorevich Shafran in 1939, and registered in 1956.

Rules

Shafran Chess is played on a 'narrow' hexagonal board that can be thought of as a hexagonal board of size 6 with some outer spaces removed. The board has 70 spaces. Piece Movement: * Queens, Rooks, Bishops, and Knights move as in Glinski Chess. - Queens slide in any of the 12 directions. - Rooks slide in any of the 6 adjacent directions. - Bishops slide in any of the 6 'diagonal' directions. - Knights move two spaces in an adjacent direction, then one space in another direction. * Kings move as in Glinski Chess, but can also castle. In 'Long Castling', the King moves three spaces toward its queenside Rook and the Rook moves two spaces in the opposite direction. In 'Short Castling', the King moves two spaces toward its bishopside Rook (i.e., the one on the side of the board with two bishops), and the Rook moves three spaces. Castling can only take place when neither the King nor the Rook being moved have moved before. * Pawns can advance one space forward without capturing. A Pawn on a Pawn start space can advance any number of spaces, up to the middle row of the board. Thus the outermost Pawns on their first moves can only advance one space, while the Pawns in the three innermost columns can advance up to three spaces. Pawns capture 'diagonally forward' (i.e., to a space ahead connected by an edge, and having the same colour). En passant capture works as in Glinski chess, except that if the opponent just advanced a Pawn three spaces, then the next player can perform en passant capture by landing a Pawn on either of the two spaces that the opponent Pawn just skipped over. On reaching the farthest rank in a given file, Pawns are promoted to a Queen, Rook, Bishop, or Knight, as the player chooses.
