A good example of why I love chess. It is full of surprises. There is humour in chess. And beauty. The beauty of simplicity. As in maths actually.

I got the diagram from Chessmaster 6000 but I am not too happy with it. The green is annoying and the size is too big. Does any of my readers know of an online resource to create nice black and white diagrams out of chess positions?

P.S. Another hint. This problem is about elegance: The white King asks the black king for a dance. It will be their last dance. White's King will have a small snack during the dance and will step out of the line of fire at the right moment for the lethal end. There are two dances, you were right in your comment, Phil. One is to the left (including an opulent last meal) and the other one to the right (the abstinent option). That is politeness and style in a macabre way. Black's King has got the choice how to dance into his own grave: with a full belly or without.
