One step further than Metamachy. This is a Chess variant with 20 different pieces on a 16 x 12 square board.

There are 192 squares and 48 pieces per side.

Teramachy can be seen as an extension of Metamachy. In Teramachy one will find again the 12 kinds of men used for Metamachy. And, there are 8 additional ones.

Teramachy is the latest and most complex stage of a trilogy:

  • 10 x 10 board: Shako
  • 12 x 12 board: Metamachy
  • 16 x 12 board: Teramachy


 

 

The board has 16 x 12 checkered squares with a white one at the right end of each player.

There are 48 pieces per side:

  • 1 King, 1 Queen, 1 Marshall, 1 Cardinal, 1 Lion, 1 Eagle, 1 Rhinoceros, 1 Buffalo
  • 2 Elephants, 2 Rooks, 2 Knights, 2 War Machines, 2 Bishops, 4 Princes, 2 Wolves, 2 Camels, 2 Giraffes, 2 Cannons, 2 Bows
  • 16 Pawns on 3rd row.

As for November 2019, the placement of the pieces of the board is the object of design play-testing. This page shows the latest preferred arrangement. Check it out until the final arrangement will be announced. Any comments are welcome in PM.

Moves And Captures

  • King: exactly as in Metamachy. It moves as in usual Chess but there is no castling at Teramachy.

    At his first move, the King may jump to a free square at two squares’ distance. It does not matter if the square jumped over is occupied or not; however, the jump is forbidden if that intermediate square is threatened by an enemy piece. When jumping like a Knight, at least one of the two intermediate squares must be free of threat. The King’s jump is not permitted if the King is in check.

  • Queen: exactly as in usual Chess.
  • Bishop: exactly as in usual Chess.
  • Knight: as in usual Chess.
  • Rook: exactly as in usual Chess.
  • Pawn: as in Metamachy. It moves straight forward one or two square from any position on the board, without capturing. It captures one square diagonally forward. As a consequence, the en-passant capture is possible every time an opposite Pawn or Prince has advanced two squares. When he reaches the last row it promotes to one of the following 5 major pieces: Queen, Lion, Eagle, Marshall, Cardinal.
  • Prince: as in Metamachy. A non-royal King who moves and captures one square in any direction, like a King but without being hindered by check. It has been inspired by medieval games like the Courier chess , an old chess variant, played in Germany, where it is called "Man". It also moves as a Pawn: he can move without capturing to the second square straight ahead. When he reaches the last row it promotes to one of the following 5 major pieces: Queen, Lion, Eagle, Marshall, Cardinal.

  • Elephant: as in Shako. It moves one or two squares diagonally. When an Elephant moves two squares, no matter what intermediate cases contain. Note that it always stays on the same color of square. The Elephant moves as the combined Alfil and Firzan (Ferz) from Shatranj, two pieces which were also present in medieval Chess and have disappeared with the birth of modern Queen and Bishop.

  • Machine: it is an orthogonal counterpart of the Elephant as it moves 1 or 2 cases orthogonally, jumping over the first case if it is occupied. Therefore, it combines the moves of old Dabbaba and Wazir found in ancient Muslim Chess variants.

  • Marshall: it combines the move of Rook and Knight. It can be found in many, many chess variants since Carrera, Bird, Capablanca and many others like Grand Chess or Gothic Chess. (under many other names: Champion, Guard, Empress, Concubine, Chancellor, etc. The later is sometimes preferred, however it is confusing since Capablanca used it once for R+N and once for B+N).

  • Cardinal: it combines the move of Bishop and Knight. It can be found in many, many chess variants since Carrera, Bird, Capablanca, Modern (Maura's) and many others like Grand Chess or Gothic Chess. (under many other names: Centaur, Minister, Equerry, Janus, Archbishop, Princess, Chancellor, etc.).

  • Lion: exactly as in Metamachy. Moves as a King (a single step move in any direction), or may jump to a position two squares away, jumping in any orthogonal or diagonal direction, or jumping as a Knight. (Inspired by Chu Shogi, the most popular Japanese chess variant, where the Lion has the same range but is more dreadful as it can move twice in a turn).

.

  • Camel: as in Metamachy. It jumps to the opposite case of a 2x4 rectangle, like an extended Knight. No matter what intermediate cases contain. Note that it always stays on the same color of squareA well known piece from medieval Muslim great Chess like Tamerlane's Chess.

  • Giraffe: jumps to the opposite case of a 3x4 rectangle, like an extended Knight. No matter what intermediate cases contain. Note that it always changes the same color of its square. This piece comes from the medieval Grande Acedrex. The same move is found in Janggi, Korean Chess, for the Elephant. Under the name of Zebra, it is also a fairy piece used by problemists for compositions.

  • Cannon: exactly as in Shako. It moves without taking like a Rook, but it takes by going in a straight horizontal and vertical line and jumping over exactly one piece. When a Cannon takes a piece, there must be exactly one piece between the original and final square of the Cannon's move - this piece may be of either color. (This is identical to the move of the Cannon in Xiangqi.)

  • Bow: it is the diagonal counterpart of the Chinese Cannon. It moves like a Bishop and needs an intermediate piece between itself and its victim to capture it. The Bow jumps the intermediate and takes the victim on its square. The intermediate is left unaffected. (Also known as Vao by problemists).

  • Buffalo: combines the leaps of the Knight (3x2), the Camel (4x2) and the Giraffe (4x3).

  • Eagle: exactly as in Metamachy. This piece is almost as powerful as the Queen and is inspired by the Giraffe from Tamerlane's Chess and the Aanca (a mythical giant bird praying elephants, mistaken for a gryphon) from Alfonso X's Grande Acedrex.

  • Rhinoceros: jumps as a Knight then slides diagonally away. This piece is inspired by the Unicorn of medieval Grande Acedrex. This piece is not the stronger but is probably the most difficult to visualize and predict on the board!

  • Wolf: jumps 2 or 3 step orthogonally or diagonally. No matter what intermediate squares contain.

Pawn and Prince Promotion: A Pawn or a Prince reaching the last rank of the board is immediately replaced by a Queen, an Eagle, a Marshall, a Cardinal or a Lion. Promotion to any other type of piece is not allowed. It is permitted to promote a Pawn or Prince to a type of piece already present on the same side; however; it is considered “good etiquette” to avoid choosing a piece which is not captured yet, if possible.

En Passant capture: Any time a Pawn or Prince takes a double step and passes through the capture square of an opposing Pawn, that Pawn may capture the Pawn or Prince as if it had only moved one square. This en passant capture must be made in the immediate move following the double step. Only a Pawn may capture en passant; the Prince does not have this option.

End Of Game: The end-of-game rules, checkmate, stalemate, etc., are identical to standard chess.
