Fairy chess piece - Wikipedia, the free encyclopedia |
 | | For example, the knight in orthodox chess is a (2,1) leaper, meaning it moves two squares in one direction (horizontally or vertically) and one square in the other (note that it could also be described as a (1,2) leaper - there is no significance to the order of the numbers). |
 | | In shatranj, a forerunner to chess, the pieces later replaced by the bishop and queen were also leapers: the alfil was a (2,2) leaper (moving exactly two squares diagonally in any direction), and the fers a (1,1) leaper (that is, it can move one square diagonally in any direction). |
 | | There are three riders in orthodox chess: the rook can move an unlimited number of (1,0) cells and is therefore a (1,0) rider; the bishop is a (1,1) rider; and the queen is a (1,1) or (1,0) rider. |
