Accelerated Constable-Spiel

Accelerated Constable-Spiel came about when I thought of an idea (Constable-Spiel) in 2023. Dr. H.G. Muller, not always liking the ferfil piece type, quickly suggested I instead use a couple of stronger piece types (a Dragon Horse and a Dragon King), and also suggested the game's setup. I liked his idea, though to be as a seperate variant - hence H.G. at the least could be thought of as the game's co-inventor (I chose the name for it on my own).

A preset is available for play on Game Courier: Accelerated Constable-Spiel




Accelerated Constable-Spiel uses the 6 piece types of orthodox chess, plus 5 unorthodox piece types:

A Warmachinewazir - also known as a Woody Rook; it moves like a wazir (moves one step orthogonally, i.e. by rank or file) or like a dabbabah (leaps two squares orthogonally).

A Waffle - also known as a Phoenix; it moves like a wazir or alfil (leaping two squares diagonally).

A Kirin moves like a dabbabah or ferz (one step diagonally).

A Dragon Horse moves like a bishop or wazir.

A Dragon King moves like a rook or ferz.


Accelerated Constable-Spiel follows the rules of chess, except as noted below.

The castling rules for Accelerated Constable-Spiel are as follows: A king that has never moved, and is not in check, can 'leap' once a game, along the first rank, to any unattacked empty square between it and an unmoved rook, followed by said rook 'leaping' to the king's initial square so as to complete castling in one single move. It does not matter if any squares in between are occupied or under attack.

Threefold repetition of position or stalemate is a draw as in standard chess, and the 50 move rule is also in effect in Accelerated Constable-Spiel (i.e. game drawn if no captures or pawn moves have been made before 50 consecutive moves by both sides). Pawns move as in chess, and can promote to any piece type included in the setup, except for a king.
