I'm compiling a piece about castling and found a couple of nice
examples in a book by Pfleger and Treppner.  They gave only positions
and I wondered if anyone has a genuine whole game scores for a game
where we see an example of the trap e.g.


Bishops Puzzle: 

I hope you will forgive my algebraic notation, but I found it easier
to read (since we know every move is a bishop).

White bishops start at b1 and d1, 
Black bishops start at b5 and d5.

01. b1-c2
02. d5-a2
03. b5-c4
04. c2-a4
05. a2-b1
06. c4-d3
07. a4-b3
08. b3-d5
09. d3-b5 (board is symmetrical)
10. b1-d3
11. d1-b3
12. b3-a2
13. d3-c2
14. b5-a4
15. a2-c4
16. c2-b1
17. a4-d1
18. c4-b5

This was not the first solution that I found, but I liked it because
it was symmetrical.

Knight's Tour

Gunno Toernberg tells me he has been working on a computer approach to the problem: you can see his endeavours at: http://w1.859.telia.com/~u85905224/knight/eknight.htm where you can have ago on his Java board.

Comment by the authors, May 15, 1996:

The number of knight's tours given in the paper is incorrect, since
the correct number must be divisible by 4.

Stone Soup

From the FRACTINT documentation

Appendix B Stone Soup With Pixels: The Authors


Once upon a time, somewhere in Eastern Europe, there was a great famine. People jealously hoarded whatever food they could find, hiding it even from their friends and neighbors. One day a peddler drove his wagon into a village, sold a few of his wares, and began asking questions as if he planned to stay for the night.

Chess Quotes

> Does anybody know the etymology of skittles?
"Once in a Moscow chess club I saw how two first-category players knocked pieces off the board as they were exchanged, so that the pieces fell onto the floor.
It was as if they were playing skittles and not chess!
