No. 234, December 2008

This issue starts with a long article by Günther Weeth about (de-)legalizing moves in anticirce proca retractors. One original in this article:

And there's an article about the Schwalbe meeting in Oestrich-Winkel (4 Oct 2008). There was a composition tourney with theme "At least one fairy battery with rear piece king, knight or pawn is fired".

Battery: "Piece X (front piece) moves, which results in a check by piece Y (rear piece)".

Solution

Find an illegal cluster with both kings and a white piece, in which the sum of the distances of the kings to their original squares is second-largest..

Solution


Fairy definitions and examples:

Mirror-anticirce: The capturing piece is reborn on the anticirce rebirth square of the opposite colour (e.g., in anticirce, a white bishop capturing on d3 is reborn on f1, in Mirror-anticirce it is reborn on c8).

Bichromatic chess: The departure- and arrival square of a move must be on a differently coloured square. E.g. bishops can't move, pawn captures and castling are illegal. Checks are 'fairy', e.g. wRd8 bKf8 isn't check, but white can deliver check with 1. Ra8.

Monochromatic chess: The departure- and arrival square of a move must be on a same colored square. Checks are 'fairy'. E.g. knights can't move, long castling is illegal, and Ra1 can never give check to the black king.
