Doublemove Chess

Doublemove chess is a popular modern chess variant. It was invented by Fred Galvin. Below, you find the rules, and the version now used in AISE, the Italian chess variant organization. Note the (subtle) differences with Marseillais Chess.

Rules

AISE version

The laws of Chess apply, modified as follow:

White starts with one move, and thereafter each player makes two consecutive moves per turn.
Check, checkmate and all rules involving them are ignored. To win by capturing the opposing King.
No en passant capture.

Original Regulations

Originally, the following rules were also used. These rules were abolished by AISE.

Every doublemove must alter the position. A player may not move a piece from a square then back to it, unless the first part of the doublemove was a capture. If a player's first move leaves him no second move save one prohibited by this rules, the games is a draw.

En passant is permitted if when a pawn makes a doublestep and does not advance further, the capture square is vacant, and the opponent captures the pawn on his first move of the next pair.
