Almost One-dimensional Chess Variants

• One dimensional chess.

The pieces are located: White - P, N, B, K, R, B, N, P + two empty fields + Black - p, n, b, r, k, b, n, p + two empty fields.

Rules:

• The King moves and takes one field in any direction.
• The Rook moves and takes by going as many squares as wanted in a direction without passing an occupied square.
• The Bishop moves and takes somewhat similar to the rook, but it stays on squares of the same color, and can jump across squares of a different color. Thus, the bishop always moves an even number of squares, and when doing so, each second square passed by must be empty, but the odd squares passed by can possibly be occupied.
• The Knight moves and takes by going exactly two fields. It can jump over the first field.
• The Pawn moves and takes only forward on one field.

Comment

Rules are the same as for Tape Chess.

In addition, pieces may change direction when crossing the centre square.

It can mean "Hello, Hans".

The setup is shown above.

• A king moves one square in an arbitrary direction.
• A rook moves any number of squares in a straight line without crossing an occupied square. It can turn a corner.
• A bishop moves by going an even number of squares on a line. It cannot jump across an occupied square of the same color, but it can jump across occupied squares of a different color. I.e., if only the third square on a line is occupied, the bishop can jump to the fourth square, but it the second square is occupied, then the bishop cannot jump to the fourth square. The bishop can turn a corner
• Knight moves exactly two squares, and can jump across the first one
• Pawn moves and captures forward and back one square horizontally or vertically. It does not promote.
