Chego is a chess variant, invented in the end of 1997 by Alfred Pfeiffer.
The name "CHEGO" is an abbreviated composition of the words "CHEss" and "GO".
The game is realized with the chess-typical material but the way and
the target of the play are more like in the Go game:
- The pieces are to be dropped on the board, not to be moved.
- The goal of the game consists of controlling at the end more free fields
than the opponent does.
A field is called "neutral" if it is attecked directly
either by no piece or by the same number of white and black pieces.
A field is called "controled" if it is attecked directly
by more white or more black pieces.
At the end of the game the player who ownes the majority of directly
attacking pieces to an free square is the dominator for this square.
- The players choose a board to play on it (by lots or by an agreement).
If nothing is declared use the standard board (8x8).
- The players choose a set of pieces to play with it.
If nothing is declared use the standard set of the normal chess
Instead of or additional to the normal chess set you may use any
number and types of pieces (from other chess variants). Also an
unlimited number of pieces is possible.
The king is an ordinary piece without any special "royal" properties.
This game has no concept of "check", "mate" etc.
Pawns are allowed to be dropped to the first rank of the board
(seen from the side of the dropping player).
In case of boards with holes should be valid (if nothing else is agreed):
Jumping pieces (knight, alfil, nightrider, dabbaba, ...) attack over
the non-existing squares, other (sliding) pieces do not so.
- At the beginning of the game the board is empty. The white player
starts by dropping one of his pieces on the board.
In the following the players drop alternately a piece or pass.
- The player who has the right to drop a piece has to do this with respect
to the following conditions:
- the piece must be placed at a neutral field;
- at least one other empty square must be attecked directly;
- other pieces (own's or opponent's) must not be attacked directly by
the new stone;
- for the own pieces the number of directly attacked empty square
must not be reduced to zero, because in this case the own piece would
be dead and this is not allowed (see the rule about capturing).
If he cannot do so or if he think it would be disadvantageous
the player may pass.
- Capturing: If a dropped stone reduces the number of the directly
attacked empty squares for an other piece to zero this leads to the
dead of that other piece. The dead piece is removed as a part of the setting
of the new stone. It is also possible to take more than one piece
by a drop, but note: Suicide of own pieces is not allowed!
- When both players pass consecutively the game ends and the
A player gets one point for each empty square that is controled by him,
and one point for each captured piece.
The winner is who has more points. In case of same number of points
for both players the game is a draw.
