Standard orthodox Chess is expanded to a 9-by-9 board in the variant which each side getting an extra Queen and Pawn, although in this game the Queens are referred to as Ministers. Dark squares are in the corners. The Ministers stand to either side of the King, making the board symmetrical, but resulting in all Bishops being on dark squares. Dr. Corinthios explained that "White squares are squares of peace and refuge."


In this game, the Queen is called a Minister, and there are two of them, but otherwise all pieces are as in orthodox Chess.


Pawns: may make a double move from the second rank subject to capture En Passant. Promote on the last rank to Minister, Rook, Bishop, or Knight.

Castling: the King castles by sliding three squares in either direction, subject to the usual restrictions.

Of course, these points are all debatable.

Ministers Chess was awarded a Seal of Excellence by the Quebec Consumers Association in 1990.
