3711 - D. Innocenti
Phénix 95, 2001

[8/5b2/6k1/8/8/1K6/8/8]

Add 3wP and 2bP for an illegal cluster (Grid chess)

[8/5b2/6k1/8/8/1K6/8/8]


Explanations:

Equipollents Circe
A piece is immediately reborn with the same displacement vector as the capturing move. (E.g. if white captures a piece on b3, starting from a1, the piece is reborn on c5)

Multicapture chess
A piece (including the king) can only be captured when it is attacked at least twice.

Grid chess
The board is subdivided in 16 small 2*2 squares. Every move must end in a different square than its starting point. (E.g. a pawn on c4 has only one possible move: a capture to b3. A pawn on a4 never has a legal move)

If any more explanations are needed, let me know.
