Prime Ministers Chess
This page contains one or more presets for playing game online with Game Courier, an online server for playing Chess variants by correspondence.
Prime Ministers Chess is an adaptation of Gabriel Vicente Maura's 1968 Modern Chess (9 columns, simple reverse symmetry, symmetric castling to either side, an extra pawn, the Prime Minister (B+N) and the Bishop Adjustment Rule) to a 9x8 board.
Note that the first alternate setup on the left also displays simple reverse symmetry, while the other two alternate setups use direct symmetry accross the board.
The code name for the main Prime Minister Chess layout (the layout same as Maura's Modern Chess) is PMC1 (or just PMC). The code names for the alternate layouts above are PMC2, PMC3 and PMC4 respectively.
RulesMost Orthodox Chess rules apply, including the objective of the game, the way pieces move and capture, en passant, check, checkmate, and the various draw situations (i.e. stalemate, insufficient mating material, threefold repetition, 50-move rule). Pawns may promote to a Queen, Minister, Rook, Bishop or Knight. The castling rule and the Bishop Adjustment Rule are below.
- O-O-Oc is Kc1 & Rd1 [Kc8 & Rd8 for black]
- O-O-Og is Kg1 & Rf1 [Kg8 & Rf8 for black]
- Players on their turn, are allowed to convert one (and only one) of their Bishops to the opposite color square by swapping places with any piece adjacent to them.
- Neither the Bishop nor the piece to be adjusted with may have moved before the Bishop swap.
