Detailed Description

A board for Courier Chess.

Courier Chess is a 12x8 board variant that has been popular in medieval Europe, especially in the countries of the Holy Roman Empire (esp. Germany, Netherlands) from the 12th to the 18th century alongside Shatranj and then Chess (influencing the transformation from the former to the latter).

The Queen and the Bishop in Courier Chess have the old Shatranj movements of the Ferz (Counselor, one square diagonally) and the Alfil (War Elephant, leaps two squares diagonally). King, Rook, and Knight have normal moves. There are additional pieces: Every side has one Mann who moves like a King, and one Schleich with Wazir movement (one square forward, backward, left or right). Every side has two Currier or Courier pieces with modern Bishop movement. Courier Chess has no Pawn double step option and no castling. A Pawn can only promote to Queen.

The effective starting position has the white Queen and Rook Pawns on ranks 4 (introducing ceremonial double steps from rank 2) and the Queen moves to g4 from g2. The black pieces do mirrorwise.

A side wins if their opponent cannot make a legal move (mate or stalemate), or has no pieces left besides their "bare" King. However, a bare King is given one chance to get level by the next move: Two bare kings is a draw.
