Achim Schöneberg: Der sLc8 kann entfernt werden, auf a3 genügt - als Block in b) - ein sB (C+ Popeye 4.85); da bleibt von den maskierten Fesselungen nichts übrig. Siehe dazu auch meinen Hinweis in "Die Schwalbe", Heft 193, Februar 2002; S. 367. (2022-01-24)

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)
A.Buchanan: Issue with animation (2022-05-25)

PR M.Caillaud: A SPG "of the future" : 2 Ceriani-Frolkin Knights and 2 Phenix Bishops exchanging their place after promotion. More original, but the weak point is that the Bishops are obviously promoted.

PR M.Caillaud: According to Winchloe, a complete diagonal by a King is a novelty. The trick to start from h8 is nice. Travel on the 1st rank is a valuable thematical addition. I wish the composer could improve it to make a straight line (f1-g1-h1) in order to produce a more striking visual effect (even if with less thematical moves).

PR M.Caillaud: A Pronkin Rook. By nature, a Pronkin is a long travel by a Pawn. Many have been produced. In this one, guessing the theme from the diagram is not obvious.
Mario Richter: The award says "SPG 8,0", but since

A.Buchanan: Hi Henrik thanks for this. I see it's a forsyth error in the draft report by Michel: an extraneous "r" at the beginning. I will correct here in PDB right now. Note that this problem is not marked C+. (2021-10-27)
Henrik Juel: Thanks, Andrew
I just received the revised judgement; the author submitted the problem with C+, but the judge found this hard to believe and made it HC+ by testing the four possible positions before 19.Lf4xYe3+ with Natch 3.3 (2021-10-28)

White to move. History of black Pawns a4 and b4?
Dmitri Baibikow
WCCC Rhodes 10/2021
1st Prize Champagne-TT B
(10+10)
White to move. History of black Pawns a4 and b4?
Henrik Juel: The pawn analysis is easy:
Black pawns captured all six missing white men by d7xc6xb5xa4 and e7xd6xc5xb4
This implies that all four missing white pawns promoted on e8 and captured all six missing black men by fxe, gxfxe, and hxgxfxe
Determining the initial retroplay is difficult, because of the threatening retro-stalemate... (2021-10-26)
Mario Richter: Hints:
1. Theme of the tourney: "The same piece captures at least 2 promoted pieces."
2. Black has only 4 uncaptures before he runs out of retromoves, and White needs at least two retractions to enable these 4 retromoves. The remaining two do not suffice to unpromote and uncapture a black piece, so White must retract in such a way that at Black's 5th retraction he can move his King (Kb4-a5) ... (2021-10-26)
Henrik Juel: Your second hint is very helpful, Mario
R: 1... c5xSb4 2.Kd4-c4 d6xSc5+ 3.Lc4-b5 b5xSa4 and e.g. 4.Sd5-b4 c6xSb5 5.Sf6-d5 Kb4-a5 6.a2-a3+ Ka5-b4
Both black pawns captured PxTxSxS (2021-10-26)

R: 1. Lf4xSg3# Sh5-g3 2. Le3xLf4+ Sg3-h5
then Lf4 to a1; a3-a2-a1=L; a2×Db3; Sg3 to b1; b3-b2-b1=S; b2×Lc3; c3×Td2
Judge Michel Caillaud: "The theme [of one piece capturing two promoted ones] in classical retro form, with the capturing piece not being a Pawn. The nice point is that -2.Lé3×Pf4+? doesn't work. The promoted Knight cannot reach a1 so it has to unpromote on b1 to unlock the cage and another promoted piece has to be produced to unpromote on a1."
Author Andrey Frolkin: "This one is superseded by P1400748 (Q+B) which is the official 1st HM. The predecessor (B+S) should be stored “for posterity” in case someone wants to compose more problems in which an officer captures 2 promoted pieces."

Henrik Juel: Black never captured, so the only way to explain the check from Lg3 seems to be
R: 1.Lf4xSg3+ Sh5-g3 2.Lg5xLf4+ Sg3-h5
and later the two uncaptured officers are unpromoted on a1 and b1 (2021-10-26)
A.Buchanan: new version in final report (2021-10-28)
A.Buchanan: Henrik may wish to update his analysis. My question: can't we just remove sBd7? (2021-10-29)
Henrik Juel: Now the solution is R: 1.Lf4xSg3+ Sh5-g3 2.Le3xLf4+ Sg3-h5
I see no immediate purpose for Pd7, but since both Andrej and Michel have accepted it, there probably is some reason for it (2021-10-29)
A.Buchanan: It’s not necessary, according to Andriy (2021-10-29)
Henrik Juel: OK
Another matter: I believe that Andrej prefers his first name to be spelled Andrey in english
This spelling is used in the WCCC-11 announcement and in the FIDE Album 2010-12 (2021-10-30)
A.Buchanan: Thanks Henrik. In the German field of the PDB author table, he is Andrij, and I've now changed the English name to match the French as Andrey. As recently as a year ago, I have seen him as Andriy in English articles which he has authored in Problemas (2021-10-30)
Henrik Juel: Rendering cyrillic names in a western language is extremely messy
Each western language has a 'standard' transliteration from russian cyrillic, but ukrainian and bulgarian cyrillic are slightly different from russian cyrillic
My bulgarian chess friend Nikolai/Nikolaj/Nikolay accepts any of those spellings, but he prefers Nikolay
Next time you write to Andrej/Andrij/Andrey/Andriy, you should ask him what he prefers, Andy...
I shall probably continue to use Nikolaj and Andrej, which seem most natural for me (2021-10-30)
A.Buchanan: I have a feeling that I did ask him before and he said that his favoured version is Andrey. On the receiving side, my only comment is that “iy” is a very rare bigram in English and almost never occurs. At least we all agree on the first 4 letters! (2021-10-30)
A.Buchanan: He should pick whichever spelling gives him the best anagram :) (2021-10-30)

R: 1.Lf4xSg3+ Sh5-g3 2.Lg5xLf4+ Sg3-h5
and later the two uncaptured officers are unpromoted on a1 and b1 (2021-10-26)
A.Buchanan: new version in final report (2021-10-28)
A.Buchanan: Henrik may wish to update his analysis. My question: can't we just remove sBd7? (2021-10-29)
Henrik Juel: Now the solution is R: 1.Lf4xSg3+ Sh5-g3 2.Le3xLf4+ Sg3-h5
I see no immediate purpose for Pd7, but since both Andrej and Michel have accepted it, there probably is some reason for it (2021-10-29)
A.Buchanan: It’s not necessary, according to Andriy (2021-10-29)
Henrik Juel: OK
Another matter: I believe that Andrej prefers his first name to be spelled Andrey in english
This spelling is used in the WCCC-11 announcement and in the FIDE Album 2010-12 (2021-10-30)
A.Buchanan: Thanks Henrik. In the German field of the PDB author table, he is Andrij, and I've now changed the English name to match the French as Andrey. As recently as a year ago, I have seen him as Andriy in English articles which he has authored in Problemas (2021-10-30)
Henrik Juel: Rendering cyrillic names in a western language is extremely messy
