klären Jahr
Teppo Mänttä: The publication year is 1993 (according to yacpdb). (2022-05-05)
Mario Richter: According to chesscomposers.blogspot.com, Yuri Grigoryevich Gorbatenko was born on 26-10-1946, so 1993 doesn't make much sense to celebrate Gorbatenko's 50th birthday. Furthermore, there is a book by A. Selivanov "Uralskije Jubilary - 1997", which, amongst others, contains the results of the JT-Yuri-Gorbatenko (s. http://selivanov.world/projects/sh1/), so 1997 seems more plausible. (2022-05-14)

Olaf Jenkner: Stellungsverbesserung: Lies besser +wDh6 und wTf6 nach e6 = aktuelles Diagramm
Trotzdem ein Dual:

1. ... c4 2.Sxb4+ Lxb4 3.Td6+ Lxd6 4.Te5+ Lxe5 5.Sf6+ Lxf6#
Die ursprüngliche Aufgabe ist C+! (A. Beine in BuB 12/2010 S.744),
was auch Gustav 4.2a bestätigt. (2023-04-05)

Also muss der sLe1 nach f2 weggelenkt werden. Das gelingt nur mit einem vorgeschalteten Manöver des wSa5. Interessant ist das Selbstmatt-typische Manöver von Deckung zu Flucht des sLe1. Möchte ich gern im Preisbericht wieder sehen“ (KHS).

Ohne wSa4 ginge 1.La7+ Kc3 2.Tc2+ d:c2#. Stünde der wLb8 auf d6, so ginge 1.Sc3 [2.Lc5+, 2.Te4+ nebst 3.Tc2+] K:c3/Th5 2.Lb4+/e3+ Kd4/f:e3 3.Lc5+/f:e3+ Kc3 4.Tc2+ d:c2\#. Ohne sBf6 ließe sich der wLb8 nach 1.Sc3 K:c3 auf folgende Weise nach d6 überspielen: 2.Tc2+ Kd4 3.Tc4+ Kd5 4.Tc5+ Kd4 5.Le5+ Ke4 6.Ld6+ Kd4 7.Tc4+ Kd5 8.Tc2+ Kd4 9.Td2 [10.Lc5+] Kc3, und weiter mit 10.Lb4+. Daher 1.Sac5! mit der kurzen Drohung 2.Te4+ Kc3 3.Tc2+ d:c2\#, aber auch der längeren 2.Sb3+ Kc4 3.Sd6+ Kd5 4.Sd4+ K:d4 5.La7+ Kc3 6.Tc2+ d:c2# (2.-- Kd5? 3.Sd4+). Gegen beides hilft nur 1.-- Kc3. Es folgt 2.Se4+ Kd4 3.S:f6 Kc3 4.Se4+ Kd4, und jetzt nicht 5.Sec5? Kc3 6.Sa4+ Kd4 7.Sc3 mit unnötigem Zeitverlust, sondern gleich 5.Sc3 K:c3 6.Tc2+ Kd4 7.Tc4+ Kd5 8.Tc5+ Kd4 9.Le5+ Ke4 10.Ld6+ Kd4 11.Tc4+ Kd5 12.Tc2+ Kd4 13.Td2 Kc3/Th5 14.Lb4+/e3+ Ke5/f:e3 15.Lc5+/f:e3+ Kc3 16.Tc2+ d:c2#.

„Ein erfreulich logisches zwölfzügiges Selbstmatt, mit überraschendem Abschluss“ (KR). „Weiß muss also die Zügel etwas lockern, um dem schwarzen König ein Fluchtfeld einzuräumen. Außerdem muss der Auswahlschlüsselzug des wSe2 das mögliche Fluchtfeld d3 des schwarzen Königs im Voraus mit abdecken. Gut inszeniert“ (KHS).

Der Preisbericht erschien in Gaudium 260, 10/06/2022.

PR: "Die beiden reziproken Unterverwandlungen werden mit Hilfe von mehreren Batterien realisiert, die zunächst aufgebaut und danach abgefeuert werden. Dabei legt der schwarze König in beiden Varianten einen weiten Weg zurück, bis er die passende Position erreicht hat. Der Materialeinsatz ist sehr sparsam, wobei der wLg6 für meinen Geschmack dennoch etwas unterbeschäftigt ist. "
