Los Alamos Extinction Chess With Bunkers
Introduction
Los Alamos Extinction Chess With Bunkers is an entry in the 44-Square Variant Contest. As the name indicates, the game is a blend of Los Alamos Chess and Extinction Chess, with some additional squares added to qualify it for the contest.Setup
The board is a 6x6 board, with a 2x2 board ("White's Bunker") underneath the squares c1,d1,c2, and d2 and another 2x2 board ("Black's Bunker") underneath the squares c5,d5, c6, and d6. Pieces are placed on the 6x6 board just as in Los Alamos Chess.Pieces
The pieces are the same as in Los Alamos Chess, except each piece has the additional power to move directly up and down.Rules
The rules are those of Los Alamos Chess (basically, regular chess with no castling, no en passant capturing, and no double-step pawn moves) except as given below:- The objective is like that of Extinction Chess: a player wins by capturing all the opponent's Pawns, or the opponent's Rooks, or the opponent's Knights, or the opponent's King(s) or Queen(s).
- As in Extinction Chess, there is no check or checkmate.
- Each piece on a bunker square can move up to the square directly above it, if the move is otherwise legal (e.g. the destination square is not occupied by a friendly piece).
- Each piece on a square directly above a bunker square can move down to that bunker square, if the move is otherwise legal.
- The bunker squares underneath each side's 6th rank are part of that rank for the purpose of pawn promotion.
- As in Extinction Chess, a pawn that reaches the promotion rank can be promoted to King.
- The bunkers are not connected to each other, so it's not possible to make a move from one bunker to another.
- When recording moves, indicate each bunker square with the prefix V. For instance, the square underneath c1 would be Vc1.
