Even bigger ! This is a chess variant with 20 different
pieces on a 14 x 14 board: such a board was used by some Maharajahs
in old India. There are 196 cases and 48 pieces per side which gives
almost the same density than for Orthodox Chess.
In Gigachess one will find again all 15 kinds of men encountered
in Shako , Tamerlane II, Perfect
12, Balance 12 and Toulousain Chess. Freshmen are the Amazon
(Queen+Knight), the Marshall (Rook+Knight) and the Cardinal
(Bishop+Knight) so often used in chess variants, and the Buffalo
is a terrific leaper combining the powers of Knight, Camel and more.
The board is a 14 x 14 checkered squares with a white one at
the right end of each player.
There are 48 pieces per side:
- 2 Bows, 2 Cannons, 2 Camels, 2 Ships, 1 Buffalo, 1 Lion,
1 Gryphon, 1 Amazon, 1 Marshall, 1 Cardinal on 1st row,
- 1 King, 1 Queen, 2 Princes, 2 Bishops, 2 Knights, 2 Rooks,
2 Elephants, 2 Machines on 2nd row,
- 6 Corporals on 3rd row and 14 Pawns on 3rd and 4th rows.
The white King is placed on the center of the second row on a
black square, the black King being on a white square. The Queen
is also placed on the center, beside the King. The Amazon is just
behind the King. On the 1st row there is the "animal side"
with Gryphon, Lion, Buffalo from inside to outside, and the "knighted
side" with Amazon, Marshall and Cardinal in this order. On
3rd row, Corporals occupy the six central columns.
- King: exactly as in usual
- Queen: exactly as in usual
- Bishop: exactly as in usual
- Knight: exactly as in usual
- Rook: exactly as in usual
- Pawn: the Pawn is almost similar to usual
Chess. There are two differences:
- It can advance one or two square from ANY position
on the board. However, its capturing move is unchanged:
one square diagonally forward. As a consequence, the
en-passant capture is possible every time the opposite
Pawn(or Corporal) has advanced two squares.
- When the Pawn reaches the last row it simply promotes
to an Amazon.
- Corporal: an extended Pawn. It can advance
one or two square from any position on the board and its capturing
move is one square diagonally forward. The improvement is that
the Corporal can also advance 1 step diagonally forward. (So,
with or without capturing). The Corporal can take en-passant
every time an opposite Pawn or Corporal has advanced two squares.
Promotes to Amazon on last row.
- Prince: this piece is simply a non-royal King.
It can be found in medieval games like the Courier chess , an old chess variant,
played in Germany, where it is called "Man". It moves
one square in an arbitrary direction, like the King, but without
being hindered by check. Like the Pawn and the Corporal, when
the Prince reaches the last row it can promote to an Amazon.
- Elephant: as in Shako.
- 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. Then, it combines the
moves of old Dabbaba and Wazir found in ancient Muslim Chess
- Lion: inspired (although with some simplification)
by Chu Shogi,
the most popular variant of the Japanese Chess. Here the Lion
may move as a King (a single step move in any direction), or
it may jump to a position two squares away, jumping in any orthogonal
or diagonal direction, or alternatively jumping as a Knight
in usual Chess. (Then this Lion has the same range but is more
restricted than the Lion in Chu Shogi which can move 2 times
in a turn).
- Gryphon: moves one square diagonally and then,
goes away of an indefinite number of cases vertically or horizontally.
It is authorized to go only one square diagonal. It can not
jump and the unobstructed path must start with the diagonal
movement. This piece is almost as powerful as the Queen and
is inspired by the Giraffe from Tamerlane's
Chess and the Aanca from Alfonso X's Grande
- Ship: moves one square diagonally and then,
goes away of an indefinite number of cases vertically, never
horizontally. It can move one square diagonally only. It can
not jump and must begin its move with the diagonal step. The
Ship is more limited than the Gryphon (which can move
horizontally). Nevertheless its move power is comparable to
the Rook and the Bishop.
- Camel: a well known piece from medieval Muslim
great Chess like Tamerlane's Chess.
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 square.
- Cannon: as in Xiangqi
and in Shako. (Also known as
Pao by problemists).
- 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 Bull (see Terachess)
- 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 and many others like Grand Chess
or Gothic Chess. (under many other names: Centaur, Minister,
Equerry, Janus, Archbishop, Princess, Chancellor, etc.).
- Amazon: strongest piece on the board, it
combines the move of Queen and Knight. It was used in the Turkish-Indian Grand Chess (as a Giraffe).
Castling: there is no
castling in Gigachess.
End Of Game:
Victory is obtained when the opposite
King is checkmated. All other types of endgame (pat, perpetual check,...)

"Giga" c'est vraiment très grand. D'accord,
on n'utilise pas ici un million de pièces ni même un
million de cases, mais ce jeu d'échecs est quand même
géant. On emploie un échiquier
14 x 14 et 48 pièces par joueur.
Il y a 20 types de pièces différents: les 6 classiques
et 14 nouvelles choisies parmi les meilleures des meilleures variantes
échiquéennes comme la redoutable Amazone.
n'y a pas que les puissants qui comptent et à côté
du modeste Pion classique on trouve aussi un Caporal, qui représente
une intéressante nouveauté. 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 pièce / nombre de cases)
est de pratiquement 1/2 comme pour les Echecs orthodoxes.
