The notation used for stopping a piece is the same as a normal move, just use the same square for from and to. This move stops the Rook at C7. Each player is required to keep an accurate list of his pieces with momentum. The pieces should be listed in order of speed, highest to lowest. The order of pieces with the same speed has no importance.
Speed is the number of squares moved during the momentum move.
A speed of 2 would represent 1 knight move. Written by Michael Fryer Play tested by Chris Muller Written by Michael Fryer . Slight editing by David Howe. This variant is an entry in the 1999 Large Variant contest. May 8, 1999.
