Loyd gab 29. ... f6? an 32. Ke7 f5 35. Kb4 f4 doch das ist drei Züge kürzer. (Also war es ein #50?)
Anton Baumann: 1.Db1 Kg5??
richtig ist: 1.Db1 Ta2 2.Kg5 Ta3 3.Kf6,Kh6 Ta2 ... 9.Kc5 Ta2 10.Kb4 h6 ... 53.Sf2# (2020-12-04)

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)

Olaf Jenkner: Die NL muß ich leider bestätigen. Nach 238. c8=D+ Kd3! dauert es einen Zug länger, weil noch 239.Dc4+ zwischengeschoben werden muß, aber es reicht zur NL. (2015-10-13)
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

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)

Duale 52. Dc5+/Da7+ Kc3 53. De3+ und weiter wie in der Autorlösung
Duale 51. Da8+/Dg8+ Kd4 52. Dd8+ Kc3 53. De3+ mit Matt im 60. Zug
Duale 50. Df7+/Dc8+ Ke5/Kd5 51. Df5+ Kd4 52. Dc5+ Kc3 53. De3+ mit Matt im 60. Zug
Duale 49. Da7+/Dd8 Ke6 50. De7+ und weiter wie in der Autorlösung
Dual 47. Dcc8+ Ke7 48. Df8+ und weiter wie in der Autorlösung
Duale 46. Da8+ oder Dce7+
Duale 43. Da4+/Da5+ Kb8 44. Daa7+ und weiter wie in der Autorlösung
Duale 39. Dd8+/De8+ und weiter wie in der Autorlösung
Ist diese Aufgabe cooked zu setzen, oder kann man das tolerieren? (2010-02-05)
Anton Baumann: Bedingung ergänzen: "ohne den Turm zu schlagen", sonst s# in weniger als 35 Zügen.
Lösung nicht korrekt, denn nach 1.d8=D+ Kc6? 2.e8=D+ Kb7 ist 3.Db8+ Ka6 1 Zug kürzer:
4.De6+ Ka5 5.Dbb6+ Ka4 6.Dc4+ Ka3 7.Da5+ Kb2 8.Dac3+ Kb1 9.De3 Kb2 10.Dce2+ Kb1 11.Kg3 c4 ... usw. gemäss Autorabsicht.
Aber 1. ... Ke6,Ke7 2.e8=D+ Kf5 wird massgebend: 3.Df7+ Kg4 4.Dg6+ Kf3 5.Dd5+ Kf4 6.Dgf5+ Ke3 7.Dde4+ Kd2 8.Df2+ Kc1 9.Dee3+ Kd1 10.Df1+ Kc2 11.Dfe2+ Kb1 12.Kg3 c4 ... usw. gemäss Autor (2020-12-23)

YM: NL from P1081833 (2010-04-19)
YM: When inputting the problem, there were inaccuracies in the solution starting from the 15th move should be 15. ... Kc1. ...And more and more!

After the 214th move, on behalf of Bachmann, is given Cook: 215. g4, etc. with a dual: 241. Dh4/Dd8 Kb2
Unfortunately, further in the position after the 250th move:
8/6D1/8/K1BD4/4L3/8/b7/b5b1/t1k4l
are some impossible moves... (2022-06-23)
YM: Cook's ending should be 251. Dh6+, not 251. Db6+?? (2022-06-23)

Vaclav Kotesovec: After more than 513 hours, Gustav 4.2c was able to test this problem! (2023-04-09)
Vaclav Kotesovec: As a composer, I would have preferred to place the white king on h5 (and ser-!=112) with multiple switchbacks, but I understand that the authors were probably more concerned with the length record. (2023-04-09)
James Malcom: That is quite the dedication to computer testing! (2023-04-10)
Vaclav Kotesovec: This problem was one of a number of problems I chose to test the new version 4.2c of Gustav by Olaf Jenkner. I always test several problems in parallel, so even though the testing times may seem long (and in the case of this problem it was rather an exception), on average it takes no more than a week to test one such problem, so I get some results almost every day. The most time-consuming problems are, of course, correct ones, and cooked ones are usually discovered much faster. I consider the fact that this problem has been completely tested as another step on the very limit of the possibilities of current computer technology. (2023-04-10)

Die ausführliche Lösung kann in 'Deutsche Schachzeitung' 03/1915 S. 86-87 und 'Bohemia' 30.05.1915 nachgelesen werden.
In der 'DSZ' mit der Forderung "Mat in 335 Königszügen" und folgenden Anmerkungen abgedruckt: "Der große Schritt in das Reich des Schrankenlosen. ... Was wir diesmal bringen, zeigt erst so recht, was alles möglich wäre, wenn die Problemkomposition alle Schranken durchbricht. Der w.K allein zieht und er setzt schließlich auch selbst (durch Abzugschach) mat. Er sucht einem der Türme, auf e6 oder g2, beizukommen und Schw. verhindert dies durch Königszüge, solange es geht. Bauernzüge von Schw. verursachen wieder, daß der w.K einmal oben, einmal unten anklopfen muß, bis die Bauern festgerannt sind und dann auch dem schw. K der Atem ausgeht. Die längste Königsfahrt besteht hier aus 35 Zügen. In der Position steckt auch manche Falle, die der Löser vermeiden muß."
Henrik Juel: The stipulation says 355 moves, but the solution says 335.
Could we get some details of the main variation, please. (2011-11-01)
Mario Richter: Correct stipulation is "Matt in 335 Königszügen". (2022-10-07)
Henrik Juel: the last move in this monster problem should be 335.Kxg3 (2022-10-07)
James Malcom: Fixed. (2023-03-07)
Henrik Juel: Thanks, Mario and James (2023-03-07)

msterkowiec: I think it's worth noting that apart from minor dual 4.Qf2/Qg2 there are also some other duals in subsequent moves:
1) 6. Qc6 lub 6.Qb7 (this repeating manoeuvre can be done both via c6 and b7)
2) 7. Qa6+ lub 7.Qa4+ (this repeating manoeuvre can be done both via a6 and a4) (2021-11-20)

Frank Müller: Wahrscheinlich sollte die in Philadelphia erschienene Quelle "The Chess Record" sein. Wer weiß genaueres zum Thema "Philadelphia Record" und "(The) Chess Record" ?

Ach, und kann das mal einer lösen? (2018-03-10)
Mario Richter: Ich denke auch, daß es sich bei der Quelle um 'The Chess Record' handelt.
Aus dem Buch 'Chess in Philadelphia' (zu finden z.B. bei archive.org oder books.google.com): "The Chess Record started in April [1873] as an independent publication, but merged in November with the Philadelphia Intelligencer. Published by George C. Helmbold. Edited by G. Reichhelm and afterwards W. H. Sayen ..."

Könnte der Lösungsmechanismus ähnlich wie bei P1086725 fuktionieren? :-) (2018-03-10)
Olaf Jenkner: Der Cook scheint bis zum 43. Zug der Autorlösung zu folgen.
Nach 44. ... g5? wird es schneller matt. (2018-03-11)
Frank Müller: Habe die Quelle nun von Philadelphia Record in The Chess Record geändert. (2018-03-11)
msterkowiec: It seems that it is even #57. After 4...d3 there is 5.Q:g7 (#34 in total)
2... g6 or 2...h6 look better
Main variant may look like this (but there are several duals there) :

msterkowiec: Actually there are precalculated data available for this type of position - they are included within installation of a free program that can be downloaded here: https://drive.google.com/file/d/1CjYhj3F2FXUuXUDe3OPILxfIVU8EFlNu/view?usp=sharing - however this piece of software is mainly in Polish, anyway it still might be usable based on this short information: https://i.ibb.co/7yTqp0G/manual.png

It is still only Polish because it was originally intended for my son who was 7 years old at this time; secondly because of relatively small interest (it has been for quite a long time available through this Polish chess forum: http://szachowe.pl/viewtopic.php?f=18&p=113611&sid=820c3eca01d996c6665b614cf85d3149#p113611 )
Please let me know... making English version (or "switchable") shouldn't take more that 2-3 days.

BTW: Program contains option not to use precalculated data: in case of this problem program still reports #57 (though it takes about 15 minutes in such case, while precalculated data show solution immediately) (2020-01-12)
msterkowiec: If anyone by any chance was interested in this piece of software and found the link above not working, here is an available download: ver. 5.1: https://drive.google.com/file/d/1JTbHkHB274JfTjm_JyaRL-UWZVIKWJjy/view?usp=sharing (be prepared for multitude of warnings from Windows Defended - anyway it's enough to trust your antivirus) (2023-05-25)

Ist es egal, ob man 25. Le7 oder 35. Le7 spielt?
Anton Baumann: ausser wenn der sK nach f8 zieht, kann der Zug Ld8-e7 zu einem beliebigen Zeitpunkt erfolgen (also 26.Le7 oder 27.Le7 ...); desgl. ist der Zeitpunkt für Le7-Ld8 nicht fix (zB. 63.Ld8 oder 64.Ld8 ...) (2022-09-08)

Cook: In The Problemist 05/1987 zeigen Mintz und Caillaud, daß diese Mintz'sche Korrektur in höchstens 330 Zügen lösbar ist. Sie geben folgende Variante an: 307. Ka7 Kb2 308. Dg7+ Kb1 309. Ka6 310.

De4+ Kb2 325. Dd2+ Lxd2#
Besser sei daher 307. ... Dxf3 mit einem s#330, das aber leider nicht gezeigt wurde.
Olaf Jenkner: See "Das längste Selbstmatt" (Die Schwalbe June 2005):
The stipulation is s#340, Mintz's correction was published 1986.
The problem is cooked in 330 moves.
The longest correct selfmate is s#255 (P1091383) (2015-01-01)
Olaf Jenkner: The matrix was invented 1903 by William A. Shinkman. (2015-01-01)
A.Buchanan: Should the keyword be renamed then? How is it generally known? (2015-01-03)
Olaf Jenkner: In my opinion yes. We should ask Frank Müller. (2015-01-03)
Frank Müller: Ich darf dazu Sir Jeremy Morse in The Problemist July 2006, Seite 430, zitieren: "... and it now seems right to call it the 'Shinkman-Bláthy-matrix'. (2015-01-03)
A.Buchanan: OK thanks: I have renamed the keyword. Detail: I have now set up both the author and the keyword so that (1) they will appear with the Hungarian diacritical "á", but (2) they can be searched with either "á" or "a" (or wildcard "%" of course). I had set up "Høeg" the same way recently, and it seems to work. Please tell me if there are any issues. (2015-01-03)

Frank Müller: Bezüglich der Namensschreibweisen unterscheidet die PDB sehr fein. Im Deutschen ohne diakritische Zeichen, bei Unicode mit diakritschen Zeichen. Jeder Nutzer kann dann die von ihm bevorzugte Schreibweise sich anzeigen lassen. (2015-01-03)
James Malcom: The claimed s#330 solution shows up in Morse's book: https://www.google.com/books/edition/Chess_Problems/VpSXCwAAQBAJ?hl=en&gbpv=0. For the most part, it can be read in the preview. I reproduced it a long time ago. The full solution is below, in English notation, hidden so it doesn't chow down anyone's page. (2021-11-06)

Anton Baumann: Deshalb ist wohl die Bedingungsaufgabe P1295542 die gültige Version; der wenig bewegliche Beamtenkönig verhindert die Abkürzungen. (2021-08-31)

Olaf Jenkner: Dr. Andreas Reinhard merkt bei P1298048 an, daß die Lösung falsch angegeben ist.
Sie ist hier und in YACPDB #188554 ebenso falsch:

156. Df1+ Ke4? 157.d3+ Kd5 158.Dxf5+ Kc6 159.De6+ Kb7 160.Db6+ Ka8/Kc8 161.Da6#/Dc7+
158. ... Se5 159.Dxe5+ Kc6 160.Dc7 Kb5/Kd5 161.Db6#/Dd6#

Richtig ist:

156.Df1+ Kg4! 157.De2+ Tf3 158.De6+ Tf5 159.Kd1 a3 160.Kc1 Kf3

Die Lösungsangabe wurde korrigiert. (2022-07-16)
Olaf Jenkner: Die Lösung war falsch angegeben, im Morsebuch steht sie korrekt.
Der Dual ist zwar ärgerlich, er ändert aber nichts an der Korrektheit, denn die Variante 169.Df1+ Kg4 ist dualfrei. (2022-07-16)

Der Dual ist zwar ärgerlich, er ändert aber nichts an der Korrektheit, denn die Variante 195.Df1+ Kg4 ist dualfrei. (2022-07-16)

Henrik Juel: Keyword Sea Snake is defined here as a long rapid (?) chess problem
I prefer the (original?) narrower definition:
White repeats a tempo-losing maneuver until Black has exhausted his pawn moves
C+ by Popeye 4.61 (2016-02-14)
Rosalie Fay: How did Walther Jørgensen define it in Søslanger? Fact is, he didn't confine his term to problems showing White tempo-losing manoeuvres. Some of his selfmates in Søslanger show White tempo-winning manoeuvres, e.g. P1089935 and P1299458. Jørgensen's P1238656 and P1193879 (composed after the book was published) are similar.

If a term specifically for problems with multiple tempo-losing manoeuvres is desired, perhaps "black sea-snake" for those, and "white sea-snake" for those with multiple tempo-winning manoeuvres?

Should mere length at least 50 qualify and length less than 50 disqualify? Morse (CP:T&R, s.17.1) writes of Jørgensen "aptly comparing the repeated sequences of moves so often found in long problems to the sea-serpent's coils". We can't ask Jørgensen (1916-89) and can but wonder what he would have made of the long studies derived from endgame tablebases. However, I think that repetition of a move-sequence for White's benefit is the cogent idea, not mere length. (2021-06-23)

An elongated version of P1372653 by four moves; the original origins are unknown

Move length record for a kindergarten problem
A.Buchanan: Any kind of assessment of soundness of this one? (2020-11-19)
James Malcom: Andrew, there is no doubt about the soundness. Sure, the ending may have a few duals, but those are generally acceptable in Blathy's correct work. Here is the proof.

All White pawns are immobile. The kingside mustn't move, or else Black breaks through and wins. Nor can a7, b2, or b6 without losing the winning chance.

The Black king is stuck, of course. The Black kindgside pawns are forever held up by White's, and the queenside ones can't move, or else Black would soon be in zugzwang and lose.

Lastly, the White king can't go after the Black pawn to shorten the game, or the Black queenside pawns must be tended to. If the White king reaches either e5 or f4, then Black plays b4!, threatening to queen soon. So the White king must hurry back, Black gets the White queen stuck as well, and it is a draw.

With a restricted White king to the given triangulation corridor, the Black king stuck, all pawns pawns frozen on their journeyes, the soundness is guranteed. (2020-11-19)
James Malcom: Furthermore, on move 99 with Black to move, chess.com analysis agrees with checkmate in move 112, albeit with a few move order corrections that I've just made. So it is still correct, with a Blathy style taste in duals. (2020-11-19)
Anton Baumann: Nach 99. - b4 gemäss Gustav noch 12 Züge; das ist #111.

James Malcom: See the now longer P1385386 with 102 moves, and also P1385390, the extension to this. (2021-01-15)
A.Buchanan: I suggest you use the keywords “superseded by” and “length record” which are designed (together with “economy record”) to track evolution of challenges. A record keyword is removed when a problem is superseded. In my opinion, you were generous to have awarded S.Manikumar an “after” rather than a “version” - the interaction of the knights is the coolest part for me - did you originate that? (2021-01-16)
James Malcom: Yes, I shall do that tomorrow, along with some others.

The bishop tempo is an old an well-used mechanism, the only one I find suitable for this task. And yes, I came up with the duel of the knights. An "After" is deserved, both as gratitude and the clever dual elimination at the end, which mine detracts from. (2021-01-16)
