Tamerlane chess

Tamerlane Chess is a strategy board game related to chess and derived from chaturanga. It was developed in Persia during the reign of Timur, also called Tamerlane (1336–1405). Some sources attribute the game's invention to Timur (Timur's Chess), but this is by no means certain. Because Tamerlane Chess is a larger variant of chaturanga, it is also called Shatranj Kamil (Perfect Chess) or Shatranj Al-Kabir (Large Chess or Great Chess). It is distinctive in that there are multiple varieties of pawn, each of which promotes in its own way.

Board

A Tamerlane chessboard is made up of 110 uncheckered squares arranged in a 10×11 pattern. Additional squares protrude from the left side on the ninth row and from the right side on the second row. These extra squares are called citadels. When the opposing king occupies a player's citadel, the game is declared a draw. No piece other than a king may occupy a citadel.

There are several ways for an opening setup to be arranged. A common one is as follows:

  • White's side (bottom row, from the left): elephant, (space), camel, (space), war machine, (space), war machine, (space), camel, (space), elephant.
  • Second row (from the left): rook, knight, picket, giraffe, general, king, vizir, giraffe, picket, knight, rook.
  • Third row (from the left): pawn of pawns, pawn of war engines, pawn of camels, pawn of elephants, pawn of generals, pawn of kings, pawn of vizirs, pawn of giraffes, pawn of pickets, pawn of knights, pawn of rooks.

    • Black's side mirrors White's.

    Pieces

    Anglicised versions of piece names are used here.

  • king – Moves as a traditional king
  • general – Moves one square diagonally
  • vizir – Moves one square horizontally or vertically
  • giraffe – Moves one square diagonally and then a minimum of three squares horizontally or vertically (a restricted gryphon)
  • picket – Moves as a bishop in traditional chess, but must move a minimum of two squares
  • knight – Moves as a knight in traditional chess
  • rook – Moves as a rook in traditional chess
  • elephant – Moves two squares diagonally and is unobstructed by pieces in between
  • camel – Moves one diagonally and two straight, unobstructed by pieces in between
  • war engine – Moves two horizontally or vertically, unobstructed by pieces in between
  • pawns – Move as pawns in traditional chess, but with no initial double move or en passant capture. Every piece (including the pawn) has a corresponding pawn. Hence; pawn of kings, pawn of vizirs, pawn of giraffes, etc.

    • Promotion

    Upon reaching the last rank on the board, a pawn is promoted to its corresponding piece. Thus, Pawn of Giraffes becomes a Giraffe, etc. Exceptions to this are the Pawn of Kings and Pawn of Pawns. A Pawn of Kings becomes a Prince, which must be mated or taken before the opponent can win. It moves as a king.

    When the Pawn of Pawns reaches the last rank, it stays there and cannot be taken. As soon as a situation develops where the opponent cannot escape losing a piece to a pawn, or where a pawn may attack two opposing units at the same time, the player must move his/her pawn to that location. Upon the second promotion of this pawn, it moves to the starting point of the Pawn of Kings. Upon the third promotion it becomes an adventitious king, which acts as a prince.

    Other

    When multiple kings are held, they may be captured as normal pieces. When only one king remains it must be checkmated. Once during the game a player may exchange a checked king for another non-royal piece. A player may move into check if he holds multiple kings. The adventitious king is the only piece that may move into a player's own citadel. This is often done to prevent the opponent from entering.
