Extended Half-Chess

I stumbled upon this while writing the HTML file for Courtyard. I suddenly realized that a certain setup on a 4x10 board would allow a two-square pawn move. Hence, I immediately started writing this game up.

This game was invented on July 28, 1999.

Preparation

Improvise a way to create a four-by-ten board. (A checkered tablecloth, maybe?) ;-)

Board Setup

The board is an four-by-ten checkered board which looks like this:

Black:
King c10; Queen b10; Rooks a10, d10; Bishops b9, c9; Knights a9, d9; Pawns a8, b8, c8, d8.

Rules

Pieces move exactly the same as orthodox chess. The two-step pawn move is allowable for any pawn, and en passent is allowed. However, castling is impossible (especially on the Kingside!).

Comments

This is the follow-up to my 5x8 variant called Courtyard.
