Symmetric Monster Chess

Introduction

Setup

As FIDE chess. However, there is eight additional squares named c0, d0, e0, f0, c9, d9, e9, f9. The c0, d0, e0, f0, contains white double-pawns. The c9, d9, e9, f9, contains black double-pawns. Each player also has one double-king initially off of the board.

Rules

FIDE chess except as following:

  1. No check/mate. Whoever has no legal moves loses.
  2. Castling is permitted out of, into, through check, due to the above.
  3. Promotion zone is still rank 8 for white and rank 1 for black, even though the extra squares.
  4. If your single-king is captured, you can no longer make any move with single-pieces.
  5. If your double-king is captured, you can no longer make any move with double-pieces.
  6. Double-pawn can make double step on your second rank (2 for white, 7 for black), but cannot be captured by en passan.
  7. Double-pawn is allowed to en passan capture a single-pawn.
  8. Double-pawn promotes to double-rook, double-knight, double-bishop, or double-queen.
  9. On your turn you can either make one move with single-pieces, or two moves with double-pieces (making only one move with double-pieces is not allowed).
  10. Turn moving with double-pieces, can be with same piece twice or with two different pieces; but it is not allowed to make a null move (a noncapturing nonpromoting move followed by moving it back to its original position).
  11. If you have not placed your double-king yet, you can place it as one part of your double-pieces move, onto any vacant space in the place where your double-pawns starts at.
  12. You also lose if you have neither single-king nor double-king on board, even if you have some legal moves, otherwise. (So, you must place the double-king when checkmated if you want to continue the game.)
