External Link: Doublebarrel Chess

The Doublebarrel slides like a bishop. Following the diagonal move, it can make a capture by jumping orthogonally over a piece of any colour, and land on an enemy piece positioned anywhere on the orthogonal behind the jumped piece, provided that any intermediate squares are empty. The jump is performed in the prolonged movement direction only (two direction alternatives). While the Doublebarrel slides along a diagonal, several orthogonals (in the prolonged movement direction) could be chosen. This makes it a quite dangerous cannon piece. The Doublebarrel's value is 4, which is more than a bishop but less than a rook (my preliminary estimation). An interesting method of introducing extra pieces on an 8x8 board is employed. A Zillions program and more information is here.
