Adrian Storisteanu: Nice cleanup, Yuri! I'd also set bPf4->f3 for an ideal mate (at the expense of a bit of a capture move)!? And, even bRh6->g6, so the bR already blocks the bK at the start, but it's just a wrong block (though a hint of things to come)... :-) (2021-06-13)

aus "Sam Loyd and his Chess Problems":
"CHARLES XII. AT BENDER."
The most famous of the Fiske-Loyd stories, and probably the best problem tale ever written, is the sketch: Charles XII. at Bender.
It has appeared in print, since the original publication in the Chess Monthly, in March, 1859, in every conceivable form and language.
In the volume of Fiske's Tales are mentioned the translations into Swedish verse, by J. G. Schultz 1868, into Danish 1876, into Italian by M. Monzecchi 1901, and into Icelandic 1901, and certainly other renderings abound. J. A. Miles put the story into English verse in his Chess Gems, 1860. "Much of the interest attaching to the piece," wrote Mr. Fiske in 1901, "is owing to the problems, which form as it were the gist of the narrative. They were suggested by the writer of the sketch to Mr. Samuel Loyd, the most ingenious and brilliant of all problem composers, who was then in his eighteenth year. The three problems were soon forthcoming, composed in a single afternoon."
The story introduces an imaginary incident during the siege of Charles the Twelfth of Sweden by the Turks at Bender in 1713. Charles beguiled this period by means of drills and chess, and used frequently to play with his minister, Christian Albert Grothusen, some of the contests being mentioned by Voltaire. One day while so engaged, the game had advanced to the stage represented in P1030415, and Charles (White) had just announced mate in three. Scarcely had he uttered the words, when a Turkish bullet, shattering the window, dashed the White Knight off the board in fragments. Grothusen started violently, but Charles, with the utmost coolness, begged him to put back the other Knight and work out the mate, observing that it was pretty enough. But another glance at the board made Charles smile: "We do not need the Knight. I can give it to you, and still mate in four!" (P1037289). Who would believe it, he had barely spoken when a second bullet flew across the room, and the Pawn at h2 shared the fate of the Knight. Grothusen turned pale. "You have our good friends the Turks with you," said the King, unconcerned, "it can scarcely be expected that I should contend against such odds; but let me see if I cannot dispense with that unlucky Pawn. I have it!" he shouted, with a tremendous laugh, "I feel great pleasure in informing you that there is undoubtedly a mate in five" (P1159789). Nor would Charles permit Grothusen to leave till he had solved the problem.
It is perhaps not very remarkable that the minister, fearful of a repetition of such chess battles, left the encampment the next day and joined the Swedes, who took sides with the enemy.
In the original three-mover, F. Amelung has pointed out, in the Baltische Schachblätter, 1900 [Heft 7, S. 274], that if the first bullet had destroyed the Rook instead of the Knight, Charles would have had an equal opportunity of showing his analytical powers by announcing a mate in six (P1159308)!

Henrik Juel: Mario, many of the years in your english text are rendered in a funny way, with i or I instead of 1 and o instead of 0, e.g. 'into Italian by M. Monzecchi igoi', where igoi probably means 1901 (2022-05-23)

im Kongreßbuch St. Petersburg 1998 nur Nachdruck im Kapitel "Aus dem Schaffen der Kongreßteilnehmer"

Das Originaldiagramm in 'Zadachi i etyudy' ebenso wie der Nachdruck im Kongreßbuch St. Petersburg 1998 haben einen sTd8, aber der begleitende Lösungstext erwähnt im Zusammenhang mit der Frage, ob zuletzt axb3,cxb3 oder cxb6 möglich war, daß auf dem Brett folgende schwarze Steine stehen: eine Dame, zwei Türme, zwei Springer, der schwarzfeldrige Läufer und 8 Bauern.
Also offensichtlich Diagrammfehler, und sSd8 ist korrekt.
Ladislav Packa: Why NL? Castling is a posteriori proof for e.p.! (2018-08-28)
A.Buchanan: Why not a3xSb4 or c3xSb4 as last move? Where is the promotion? (2018-08-28)
VL: Yes, it definitely looks as AP (with thematic illegal castling avoiding tries). I suspect missing two b knights somewhere: "superfluous" similarly to the b rooks...
wBa5 proves to be a promotee. Bl to move of course. (2018-08-29)
A.Buchanan: I agree with VL. WinChloe adds sSh1 & sTd8 (the latter is illegal with 8sB+2sT on the board already). If we add sSh1d8, then the problem is sound forwardly and retroly. The missing light sL can't just have been captured. (2022-05-24)
Mario Richter: Adding black Sh1+Sd8 is correct: obviously the original diagram is misprinted, the accompanying solution text speaks of: one black Queen, two black Rooks, TWO black Knights, one black dark-squared Bishop and 8 black Pawns. (2022-05-24)

Korrektur der P1088078.
Mit einem neuen, sehr ideenreichen Finale startet Mintz einen neuen Versuch zur Eroberung des Längenrekordes im bedingungslosen Selbstmatt.
Olaf Jenkner: I tried hard to cook this one and I'm very pleased to see it could be sound. I consider this problem to be the longest correct selfmate.
Congratulations, Mr. Mintz! (2011-11-13)

YM: Before the publication of this S#255 (and previous S#259) has been a candidate for record shorter S#244 (with one of two endings of Karlheinz Bachmann).
Jeremy Morse found a way to extend the problem S#244 in two moves, but because of my original problems with the new endings (cook - problems!) did not published it.
I hope in future joint S#246 would be in publication, like I wanted. (2015-10-14)
YM: Also is possible an oriinal ending! A new idea almost automatically lead to a longer problem - S#270.
...today was sent like correction of s#255. (2015-11-06)
YM: Now the Record position is:

Yaakov Mintz &
Christopher Jeremy Morse
nach Karlheinz Bachmann

6K1/1sq5/2p5/p1PBB2p/1pQ1S1pP/b4P1p/p5pr/rs4kb, S#224

('The Problemist', May 2017, Vol 26 No 3, Page 103) (2021-01-04)
James Malcom: So now you claim one move more than the still standing P1176536? (2021-01-04)
YM: To James Malcom: Alas, in all other versions, were found cook(s)...
...In S#224 a different mate. (2021-01-05)
James Malcom: Mintz, do you have an email where we can further discuss this? Mine is rewandemontay@gmail.com (2021-01-05)
