One step further than Metamachy. This is a Chess variant with 22 different pieces on a 16 x 12 square board.

There are 192 squares and 48 pieces per side which gives the same density than for Orthodox Chess.

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 10 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 Amazon, 1 Sorcerer, 1 Lion, 1 Eagle, 1 Rhinoceros, 1 Buffalo, 2 Cannons, 2 Bulls,
    2 Bows, 2 Camels, 2 Antelopes on 1st row,
  • 1 King, 1 Queen, 1 Marshall, 1 Cardinal, 2 Princes, 2 Bishops, 2 Knights, 2 Rooks,
    2 Machines, 2 Elephants on 2nd row,
  • 16 Pawns on 3rd row.

The white King is put on the center of the second row, on a black square, the black King being on a white square. The Queen lays on the King's left side and the Marshall on the King's right side. The Cardinal is close to the Marshall.
On the 1st row, the Amazon is behind the Marshall and commands a side with Lion and Buffalo. On the opposite side, there is the Sorcerer commanding the Eagle and the Rhinoceros.

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 can make a 2-steps jump, horizontally, vertically, diagonally or like a Knight, providing that he is not in check and that the overpassed and the arrival squares are not under attack. The overpassed square may be free or occupied.
  • Queen: exactly as in usual Chess.
  • Bishop: exactly as in usual Chess.
  • Knight: as in usual Chess.
  • Rook: exactly as in usual Chess.
  • Pawn: exactly 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 major pieces: Queen, Lion or Eagle.
  • Prince: exactly 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 major pieces: Queen, Lion or Eagle.

  • 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.).

  • Amazon: the strongest piece on the board, it combines the move of Queen and Knight. An old idea, used by Russians instead of the Queen in the 18th century.

  • 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).

  • Sorcerer: it moves like a Queen and needs an intermediate piece between itself and its victim to capture it. The Sorcerer jumps the intermediate and takes the victim on its square. The intermediate is left unaffected. Like the Queen is Bishop + Rook, the Sorcerer is Cannon + Bow.

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

  • 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.

Castling: there is no castling in Teramachy. There is the King's initial double step instead.

End Of Game: Victory is obtained when the opposite King is checkmated. All other types of endgame (pat, perpetual check,...) are classic.

"Tera" c'est encore plus grand ! Démesurément inouï. L'échiquier présente 16 x 12 cases et il y a 48 pièces par joueur, soit 3 fois plus que pour les échecs réguliers.

Il y a 22 types de pièces différents: les 6 classiques, 6 déjà rencontrées sur la Métamachie et 10 nouvelles. Comme toujours, toutes ces nouvelles pièces sont faciles à se remémorer et ne posent aucun problème au joueur classique qui voudra s'amuser.

La densité (nombre de pièces / nombre de cases) est de 1/2 comme pour les échecs orthodoxes.
