Tamerlane Chess Set

Description

Tamerlane chess is a medieval chess variant created by Timur, founder of the Timurid Empire in what is now Central Asia and the Middle East.
It is played on a 10x11 board and features pieces no longer used in modern chess as well as citadels, special squares that can be used to force a stalemate. Additionally, each pawn corresponds to a piece and promotes to that piece when it reaches the last row. The pawn of pawns has a special promotion: Once it reaches the last file it is immobilized until a board state where 2 opponents pieces are in a position to be forked by a pawn. Then the pawn of pawns is immediately moved to that square. If the pawn of pawns again reaches the last file it is promoted to an adventitious king which moves like the king. If more than one king exists on the board for a player (the king, the promoted pawn of kings, or the adventitious king) then check may be ignored until only one king remains.
Pieces per side:
1x King
1x Ferz or General/Counselor
1x Vizier or Wazir/Governor
2x Knight
2x Rook
2x Zurafa or Giraffe
2x Dababba or Siege Engine (depicted as a bombard)
2x Camel
2x Picket or Scout (similar to modern bishop, but must move at least 2 spaces)
2x Elephant
11x Pawns
11x Pawn promotion pedestals
There are 3 starting arrangements that can be played. Pictured above is the "masculine" array, there is also the "feminine" array, and the "third" array which may not use the citadels.
For a full set of rules and variations, I recommend A World of Chess by Jean-Louis Cazaux and Rick Knowlton. Pages 30-35 describe the piece move sets, starting arrays, pawn promotion, citadel stalemate, etc. in detail.
