Henrik Juel: The loong castling in Paul's cook is new to me
But it does satisfy the formal castling requirements (2018-11-03)
A.Buchanan: Jacobi has this castling as an option for Vertical Cylinder (2020-05-17)
A.Buchanan: But there is no flag in Jacobi for null moves, I think - don't know what the default is. (2020-05-17)
Henrik Juel: The default for Jacobi 0.7.4 is the natural one: allowing null moves (2020-05-17)
Étienne Dupuis: The long castling "cook" was found shortly after this problem was published and it spanned a lively debate on the Retro Mailing List (see September 2002 mailing list archives) on whether the problem was cooked or not (i.e. should the extended castling be considered part of the basic rules of vertical cylinder chess). As of myself, I had never thought that 0-0-0-0 would be a legal move.

At the time I suggested moving the black rook from d8 to h8 in the diagram, preventing the solution with the extended castling, to make everyone happy, but this suggestion apparently got lost. (2021-01-30)
A.Buchanan: I am not a fairy expert, but I know that a knight rose is allowed to execute a full circle and return to its starting square, if there are no pieces occupying any of the intermediate 7 squares. Indeed, on a big enough board, there are 8 circuits which a knight could choose between. See https://chess.stackexchange.com/questions/26911/16-roses-16x16-board-maximum-double-attacked-squares-while-all-256-squares-are (BTW: these 8 circuits can be blocked by just 4 pieces: e.g placed at positions one left-knight move from the centre.)

Amongst the countless circe variants there must be situations where the effect of a capture is null, both pieces returning to the same squares. No-one would disallow such an effect.

But rather than have case-by-case law on this, I would prefer a general fairy principle. To me, it's cool if a circular move saves a tempo, and it's a nice novel feature to emerge from fairy board/piece/condition. And it comes from the simple principle that pieces move without regard to whether the start square happens to coincide with the end square.

It's fortunate that Etienne found an ingenious way to salvage the problem. He says that this will make everyone happy: haha I'm not happy if it allows us to "kick the can down the road", and avoid deciding what the default position should be: are circular moves ok? To me, any composer's right to "freedom of expression" is dominated by the solver's right to clarity of stipulation, to not have his or her time wasted. (2021-01-31)

Years: 1997

Das U.S. Problem Bulletin stellte mit Nr.105/106 (Januar-April 1997) sein Erscheinen ein. Der Preisbericht für 1997 von Eugene Rosner erschien zunächst in StrateGems 14 (2001), S.66, wo die Aufgabe zusammen mit P1064003 den 1.-2.Preis erhielt. Nach genauerem Überdenken änderte der Preisrichter sein Urteil in StrateGems 17 (2002), S.15. Im FIDE-Album 1995-97, A29, steht fälschlich "1.-2.Preis" statt "1.Preis".

PR R.MacCracken: The wR must screen on b7 to allow castling, and then an epic pursuit unfolds, with Black's Rook chasing White's down the board. The pursuit spans an impressive 16 ply of Rook moves, starting with White's Re8-e6. Nice to see a good, long PG without promotions or lots of captures.

The unassuming Rex Solus position hides a real treasure - a spectacular retro play, containing a length record and largest number (11) of uncaptures in Anti-Circe Proca retractors. (judge Ivan Denkovski)
Henrik Juel: Incredible problem
The position after the retroplay is something like
4s3/1b3l2l/1b5b/5b1t/l4b2/3b2sl/3t1K1k/8 (1+15) (La4 could also be on b5 or d7)
White mates with 1.Kf2-g1#, which is legal in Anticirce because Se8 prevents 1... Kxg1(Ke8)??
The flights for black Kh2 are blocked by Sg3 and Lh3 (2021-06-26)

Happy Holidays
By Mike Prcic

As the holiday season approaches, we are reminded of the current COVID-19 pandemic. It has been a difficult time for many of us. I have been in touch with many composers. Many are suffering, especially the older ones. Some are not infected but still need medical care, which is not available, since the hospitals are swamped with COVID-19 patients. One of StrateGems’ editors lost his younger brother to COVID-19. A long-time subscriber from Italy informed me that his whole family was infected. He had the hardest time with the infection but survived and is now COVID-19 negative.
On a positive side (if there is such a thing), we all have ample time for composing (and in my case for playing online bridge). WCCT-11 should benefit from the pandemic. Nevertheless, I hope the vaccine arrives soon, is effective, and that we all can go back to our lives.
To brighten the holiday spirit, Kurt Keller has sent a composition that reminds us of the Christmas tree. Thank you, Kurt!

Originalversion s. P1061007
James Malcom: This is a hair different from P1061007, and yet it is what David Zimbeck gives on his site (as linked above) under the same source. If someone could dig up the 2002 issue of Strategems, that would be excellent. (2021-05-28)
Henrik Juel: I do not have access to old StrateGems issues, but the two versions have very similar solutions, including the duals 1... Db6 2.cxb7,Ta5,Tc5,Td5
Another point: the Keywords are inaccurate, to put it mildly... (2021-05-28)
