In the game of Symmetric Sissa we have no bishops and queens, but Sissas and cardinals.
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 cardinal has the combined moves of bishop and knight.
The king goes always three steps in castlings.
Symmetric Sissa is a chess variant invented in 1998 by Carlos Cetina. The piece called Symmetric Sissa is taken from another chess variant of Cetina, called Coherent Chess. The piece is named after the probable inventor of Chaturanga. |
