# Magnetic Chess

Joao Pedro Neto and Claude Chaunier invented this variant in the end of 96, and played two games showed below. They think it is a very dynamic variant, where things can turn against a player in a very fast way (check game 2). It is possible to transform pawns in real missiles!!! :)

The magnetic rule can be seen as a game transformer (GT), because we can use it on many other games. Magnetic Progressive, ...

## Rules

1. The FIDE rules apply, except in the following.
2. There is no notion of check, checkmate or stalemate. The player capturing the opponent's king wins.
3. Every piece has a charge generating a magnetic field, except the two kings which have a neutral charge. White pieces are positive, and Black are negative (or vice versa, of course :)
4. When a piece is moved to a specific square, their closest neighbours at the same rank and column (not diagonal) are repelled if they have the same charge (hence the same colour), and attracted if they have an opposite charge (hence have different colours). A king isn't repelled or attracted, doesn't repel or attract and has a blocking effect on the magnetic field lines (in the example, the bishop Bd8 is not attracted by the queen because of Kd6).

Eg,

```   8 . . . b . . . .       . . . b . . . .
7 . . . . . . . .       . . . . . . . .
6 . . . K . . . .  Qd5  . . . K . . . .
5 q . R . . r P .   =>  q R . Q r . P .
4 . . . Q . . . .       . . . b . . . .
3 . . . . . . . .       . . . . . . . .
2 . . . b . . . .       . . . . . . . .
1 . . . . . . . .       . . . . . . . .
a b c d e f g h       a b c d e f g h
```
5. There is no en-passant rule.
6. In castling, the changes are made by the rook movement.
7. A white pawn in the 1st or 2nd rank, or a black pawn in the 7th or 8th rank, can move 2 squares ahead, even if it has already been played before.
To be precise: pawns are also considered to be pieces, and the effects apply to pawns as to the other types of pieces.
