Pacifist Chess



These non-violent rules may be applied to any form of Chess.

There are no captures. Pieces are converted.

Conversion occurs when the amount of persuasion exceeds the

amount of support. Pieces persuade and support according to

their standard attack moves. Opposing pieces persuade, friendly


A turn consists of moving a friendly piece to a vacant cell. If

that piece is not overly persuaded, it then may be used to convert

opposing pieces. The player then converts any and all appropriate

opposing pieces by replacing them with corresponding friendly

pieces. If the move results in any pieces being overly persuaded

by the opponent, those may be replaced by the opponent with

corresponding opposing pieces. Newly converted pieces can then

be used to determine the level of persuasion of other pieces.

The turn is ended when all adjustments to the field are complete.

It is possible for pieces to persuade or support through other

friendly pieces. For example: Rooks and Queens in the same orthogonal

or Bishops and Queens in the same diagonal.

The Pawn is forbidden to move through a cell which is overly persuaded

during its initial two-step move. A un-moved Rook which has been

converted, though re-converted, cannot participate in castling.

A King is allowed to move to cells which are being persuaded as

long as the level of persuasion is not greater than its support.

The game is won when the opposing King is converted and the opponent

is unable to perform a move which results in claiming a converted



Evaluation of persuasion and support can take several forms:

1) total number of pieces

2) total value of pieces

3) average value of pieces

Each of these can have an effect on the game. The form should

be decided before play.
