In the game of Coherent Chess we have no knights, but Sissas.
A Sissa moves as follows: in one turn, first, the Sissa moves one or more squares like a rook or a bishop, and then the Sissa moves the same number of squares like the other of the two (bishop or rook). So, the Sissa has the following options: - First, it moves a number of squares as a rook. Then it makes a corner of 45, 135, 225, or 315 degrees, and then moves the same number of squares as a bishop. All squares that are passed by must be empty, i.e., a Sissa does not jump over pieces.
- First, it moves a number of squares as a bishop. Then, it makes a corner of 45, 135, 225, or 315 degrees, and then moves the same number of squares as a rook. Again, all squares passed by must be empty.
The king goes always three steps in castlings.
Coherent Chess was invented by Carlos Cetina from Mexico in the 1980s. It is the first game where a Sissa is used (still not with this name). Later this piece was named by Cetina after the probable inventor of Chaturanga as Sissa. |
