Erich Bartel: Hier wird der Vorwurf unnötigerweise auf 4 Züge aufgebläht. Zudem
ist in dieser Aufgabe kein kritischer Zug vorhanden,denn das kritsche
Feld g5 wird nur geräumt, nicht überschritten. Des weiteren ist der
Zug 1.h2 vollkommen irrelevant und überflüssig, da er mit dem Thema
nichts zu tun hat.Vielleicht war dies alles seinerzeit ein Grund,
dieser Aufgabe einen 2.Preis (?!)zu geben. (\eb)

Viktoras Paliulionis: The problem shows a rare theme - Brunner-Zepler doubling. Rh5-f5 is an anti-critical move there. Additionally, there is Klasinc wR-wR. (2021-02-11)

7 Black pawn captures: QRRBSSPP
2 White pawn captures: QSP
If White just moved, then d2xe3, and wBc1 retro blocked. This means all captures accounted for, but how did h pawns pass?
So, WTM.
There are numerous BWBW and BWB mates, but there is only one WBW mate.
A.Buchanan: Odd. As h#2 there are many solutions, not just the nice slow-rolling wPb one. And these are all eliminated for both retropat reasons and because they are longer than the actual one. Why is the stipulation not just h#2? (2021-10-20)

A.Buchanan: According to WinChloe, 8/8/5p2/8/1n2pp1p/1p1prn1k/1Pp3bp/KB4rq was a 1998 repair by Chris Feather himself, but Yuri's fix is more economical: bravo! (2021-03-04)
Viktoras Paliulionis: Correction: P0577628. Capturing a pawn is better than capturing a bishop. In the Yuri's version bSb4 can be changed with bPd5. (2021-03-05)
A.Buchanan: Hi Viktoras, thanks for this. Taken in isolation, capturing a pawn is of course better than capturing a bishop, but is it worth an extra cook-blocker on the board? The problem to compare with CJF's fix is your version 8/8/8/3p4/4bp1p/1p1prn1k/1Pp3pp/KB4rq 3+14, with a knight less. Personally, I might actively prefer that Le4 has another role as well as being a blocker, but maybe this isn't the common view. If Le4 moved around, I might have a different opinion. Does CJF opine on this point in "Black to move?" (2021-03-05)
Viktoras Paliulionis: Capturing of black guarding piece is always looks rude (bB guards the mating square), in addition, we get double motivation for the move. CJF justifies even two completely unnecessary white pawns on the board to emphasize the idea. (see 167). For 143, he suggests a less economical position to make motivation cleaner. (2021-03-05)
A.Buchanan: Ok very clear thanks! (2021-03-05)

The knight undertakes a 12 move captureless roundtrip to prevent twice that the pheni\x queen gives harmful check (this ties the record for the longest captureless roundtrip by a knight). Not computer tested.
Reto: A version of this is C+ by Stelvio 2.0: Ra4-d4 and Qb4-e4 (the content remains the same, but easier to test). (2023-12-17)

Inhalt:
Die Verführung scheitert daran, dass kurz vor Toresschluss die sDg3 im Wege steht.
Deshalb muss diese Dame vorausschauend „aus dem Spiel“ genommen werden. Paradoxerweise geschieht dies, indem sie in der Lösung den aktiven Part übernimmt, und die in der Verführung aktive sDe7 übernimmt dieses mal den „passiven“ Part.
Außerdem sehen wir in der Lösung einen Platzwechsel von sDc3 und sSf6 innerhalb der Fesselungslinie.
