Mario Richter: For the retraction of ep-captures, the animation engine puts the uncaptured pawn on the wrong square. (2020-12-09)
A.Buchanan: Well spotted Mario. Suggest that you drop a quick email to Gerd? If that's not convenient for you, let me know and I will (2020-12-09)
Mario Richter: Gerd is informed. (2020-12-09)

S N Ravi Shankar: This problem is not mine. (2019-01-02)
Mario Richter: My first guess for the solution was:
R: 1. Ke2xLf1 2. Kd3xLe2 3. Kc4xLd3 4. Kb5xLc4 5. Ka6xLb5 Lc6-b5+ 6. Sd7xLb8, dann 1. Sb6#, but that doesn't work because of 5. ... Ld7-b5+!
Does someone see (or know) the correct solution? (2019-01-03)
Henrik Juel: No, because with 1... Lh3-f1+, 5.Ka6-b5 thr. 6.Sd7xLb8 fails similarly on 5... Ld7-h3 (2019-01-03)
S N Ravi Shankar: Does adding a black knight on e6 cure? 1. Ke2xLf1 2. Kd3xLe2 3. Kc4xLd3 4. Kb5xLc4 5. Ka6-b5! followed by 6. Sd7xLb8 and now 1. Sb6#. (2023-02-20)
S N Ravi Shankar: The problem appears to be sound. 1.Ke2xLf1 2.Kd3xLe2 3.Kc4xLd3 4.Kb5xLc4 5.Kb6-b5! followed by 6.Sa6xSb8 and now 1.Sc7#. (2024-02-18)
A.Buchanan: WinChloe also gives the same composer. A curious situation, but at least the problem attributed to you appears to be sound! (2024-02-19)
Adrian Storisteanu: Above the "diagrammes" diagram there is: R. SHANKAR, Inde. In the volume index, under RETROS: this is the only problem of a composer named (just) "SHANKAR" (one original), while "RAVI SHANKAR" is a different author (with two originals). (2024-02-20)
A.Buchanan: I suggest that S.N.Ravishankar check the reaponse to the query (A='Shankar' or a='Ravishankar') AND NOT A='Shankar Ram, Narajan' as there are many other similar retros which are attributed to Ravishankar. If he can state here which ones are not his, I will happily modify the data. (2024-02-21)

Ladislav Packa: Why not 1...f7xLg6? (2020-07-19)
Mario Richter: Ladislav, because of the Maximummer condition 1...f7xLg6 is illegal - Black would have been forced to play f7-f5! (2020-12-09)
A.Buchanan: And this is why the key is 1. h5xBg6! and not 1. f5xg6? which would allow f7xLg6, as f7-f5 would be blocked. Did this composition ever get fixed? (2020-12-09)

WD zeigt mit seiner Aufgabe eine wohl neue Methode, das Feld e8 dem sK unzugänglich zu machen, so daß der wK seinen schwarzen Gegenspieler mattsetzen kann (WD: "Lenkung einer sFigur nach e8 durch direkten KK-Kontakt.“).

Zunächst ohne sBc6 veröffentlicht, Korrektur in 'Die Schwalbe' Heft 260 (April 2013) BuB S. 109: "Der Autor ergänzt gegen den (nach der Veröffentlichung selbst gefundenen) Dual 2.Kc2:Tb1 einen wBc6 (nun 4+3 Steine)"

In the foreplan White decoys an uncaptured black Rook on to the square of origin of wSb1. Consequently in the forward play there is no longer a double check but only a single check by wK that Black has to parry with De1# (2022-05-19)

Henrik Juel: -1.Td1? thr. -2.0-0-0, 1.Tb8# fails on -1... Lf1xPf2!,
showing that Black has promoted f2-f1=L, and wK has moved
-1.Td1xLh1 any -2.0-0-0, 1.Tb8#
-1... Lf1xPf2?? is now illegal, as it would entail six captures by [Pc7,e7], which is one too many, because [Lc1,f1] were captured by officers (2018-10-03)
Mario Richter: Another try is R: 1. Th4xTh1? (2018-10-04)
Henrik Juel: Mario's try would permit Black to mate, another way to thwart the white aim of mating:
R: 1.Th4xTh1?? Lf1-g2+ and 1... Lh3#
The entire stipulation should read: -2 & #1, Proca retractor
to make the forward stipulation clear (2021-03-03)
A.Buchanan: @Henrik The stipulation always was correctly input, but for some reason did not display properly. Thanks for spotting. I jiggled it and it now mysteriously is willing to display properly! (2021-03-04)
