This page contains one or more presets for playing a game online with Game Courier, an online server for playing Chess variants by correspondence.

Prime Ministers Random Chess is a new 9x8 variant inspired by Gabriel Vicente Maura's 1968 Modern Chess (9 columns, symmetric castling to either side, an extra pawn, the Prime Minister [B+N]) with some random concepts & the castling rule from Fischer Random Chess (FRC).


There are 8,400 possible starting positions!

Pieces

The Orthodox Chess pieces plus an Archbishop (Bishop + Knight) and 9 pawns.

Setup

Random setup of the pieces, with the restriction that Bishops start on opposite colors, and the King be placed somewhere between the Rooks to allow for the modified castling rule.

Rules

Orthodox Chess rules apply, including en passant, with the changes below.

  • Symmetric Castling to either side. In the 9x8 setup castling is short (O-O) on both sides of the board:

    • O-Ob is Kb1 & Rc1 [Kb8 & Rc8 for black]
    • O-Oh is Kh1 & Rg1 [Kh8 & Rg8 for black]
