This must be explained:
The changed geometry takes it, that on the left besides a4 and from view of the white player on the right next to h5 triangles arises which are included in the board. The fields a4 and h5 are finally halved virtually. That's it.
Field 4 consists of the triangle on the left next to a4 and the left lower half - also triangular - of the field a4.
Field 5 consists of the triangle - from view of the white player - on the right next to h5 and the upper half - also triangular - of the field h5. |
|
Finally has to be mentioned, that because of the new geometry the following happens: · The transposed halves of the board cause a change in the line - e.g. d4 to e5. · In same way a change takes place in the diagonal - e.g. d4 to d5. · The right corner square of the white player is unchangedly white while the right corner square of the black player now is black. |
|
This looks primarily like a geometric pastime. However, this isn't it. Because the board has certain qualities.
To take it to the point: · The king can be checkmated with only one piece. · The bishop can change his color diagonal. This asks for an explanation. We start with the statement that an opposing king can be checkmated with only one piece and let's have a look to the squares 4 and a4 as well as 5 and h5. |
|
The Switches The fields 4 and a4 as well as the fields 5 and h5 are "switches" ("Weiche"). They make combinations possible which also don't exist in the usual chess . This concerns in first line the pieces queen and rook |
|
With the help of a switch a move can be executed "forkedly". That means that with one move is it possible to reach far more squares than queen and rook are able in the usual chess.
Queen and rook on a1/a3 can checkmate an opposing king standing e.g. on a8 without help of other pieces. Queen and rook have on the lines a1/a3 and h8/h6 powerful positions. |
|
It still goes on.
A look to the bishop shows the following: The bishop moves to any square along a diagonal on which it stands (FIDE rule). This means that the bishop remains during the game on the square-colour on which he initially stood. A change of the colour of the square isn't possible. This is in principle a 'loss' for the chess. |
|
The Transfer Fields If in the course of the game the 'color change' of the bishop shall be carried out, then a color transfer must take place. It is clear that this isn't possible with the traditional squares of the usual chess. In PowerChess a change is possible with the help of the Transfer Fields. |
|
The fields 4 and 5 are "Transfer Fields". They make combinations possible which don't exist in the usual chess. This concerns in first line the pieces bishop and knight |
|
This is my PowerChess! Where can a king be checkmated with only one piece? Where can all opposing bishops attack each other? This is possible at PowerChess. |
|
However, that's not all. Some rules have to be taken into account also at PowerChess.
At first the following must be noticed, however. In PowerChess only the pieces queen and rook face each other in the initial position. This is due to the new geometry of the board. |
|
The Rules Let's have a look to the switches. Regarding the switches the following rules have to be taken into account:
· The position on the Switches must be clear. Either field 4 or field a4 must be occupied. This applies to field 5 or field h5 in same way. The player must show this by clear seek of his piece. · The Switches can always only be occupied by one piece. On an Switch a piece will be captured on the field on which it stood - either on field 4 or on field a4 respectively on field 5 or on field h5. · Occupying a square of the switch closes the switch for the move over the switch. A piece on 4 prevents therefore a move a1-b8. · A move between field 4 and field a4 respectively a move between field 5 and field h5 isn't possible. Horizontal the next field which can be reached by 4 is field b4 (g5 by 5). |

The knight finally requires our attention.
In the usual chess the FIDE rule means: The knight moves to one of the squares nearest to that on which it stands but not on the same rank, file or diagonal. It does not pass directly over any intervening square.
Due to the changed geometry of the board a supplement of the definition is required for knight moves to determine the square distances. The rule has been defined by Alfred Pfeiffer (Technical University Chemnitz) and means:
The knight moves to one of the squares which a king in two moves from this square can reach and which lies not on the same rank, file or diagonal. It does not pass directly over any intervening square.
Ups! This seems not quite easy to be. However, it is actually quite simply and also natural. At an example this shall be clarified. In the example the knight starts from square 5. With the FIDE definition for the knight move the squares g7, f6 as well as f4 and g3 can be reached easily. But in PowerChess Square e4 also can be occupied because e4 can be reached by 5 with two king moves. (cf. picture 9)
These are my explanations about PowerChess. |

What is new apart from the name? At first the board. The board is based on the 8X8 arrangement of the usual chess. The upper game half has been moved one square to the left - a new geometric arrangement of the board is born. The new geometric arrangement causes that two new fields join. These are the fields 4 and 5. The fields 4 and 5 are full-function fields |
