 Double Move Double Chess 

by Vadrya Pokshtya

Inspired by Charles Gilman's Quadruple Besiege Chess setup and Fred Galvin's Double-move Chess.

Double Move Double Chess is played on two boards, put together, with two sets of pieces.

Rules.

Double Move Double Chess is played on a rectangular board of sixteen ranks and eight files.

The setup is as given below:

The standard rules of chess and the movement of chess pieces apply, with the exception of the following:

1. White starts with one move, and thereafter each player makes two consecutive moves per turn.

2. No check, no checkmate. To win the game of Double Move Double Chess, a player must capture two opponent's kings.

3. There is no initial double-step move. The pawn only moves one square forward. Pawns that reach the farthest rank of the board are promoted to knights, bishops, rooks, or queens.

4. There is no castling.

5. Each double move must change the position on the board. A player may not move a piece from a square then back to it, unless the first part of the double move was a capture.

A draw is possible by mutual agreement of the parties or if no pawn move or any capture has been made in 50 double moves.
