(P. A. Petkow). WoW: "Ein Selbstmattmehrzüger mit zwei Lösungen und Dreifach-Umwandlung in die Leo-Familie: Ohne Zweifel das beste Problem, das ich in der Märchenschachabteilung in letzter Zeit gesehen habe. Wer das nicht gelöst hat, hat wahrlich viel versäumt (ich hatte schon aufgegeben und den Brief zugeklebt). Da gibt es zum ersten Mal eine 5 in der Wertung." Nun, dann sind wir auf die Lösung gespannt: 1.VAg4! (2.c8=VA K:e8 3.VAb7 Kd7 4.VA:e4 Ke6 5.VAf5) 1.- e3 2.c8=PA K:e8 3.PAc7 Kd7 4.PAc4 Ke6 5.PAe4, 1.- PAe2 2.c8=LE K:e8 3.LEc7 Kd7 4.LEa5 Ke6 5.LE:a2 - "Auch wenn die Abspiele etwas eintönig wirken, die UW in alle drei verwendeten Märchenfiguren ist perfekt gelungen!" (MS) Auch sonst war die Begeisterung groß, z. ,B. bei RobS: "Kampf der wB/D- gegen die sV/LE-Batterie mit V-Mattzügen. In der Drohung treten nur wV-Züge, in der einen Variante nur wLE-Züge, in der anderen nur wP-Züge auf. Hochrangig." Oder RJB: "Chinesische AUW in Verbindung mit weißem Batteriespiel auf der 7./8. Reihe, gekonnt in Szene gesetzt! Die unterschiedlichen UW-Steine erlauben jeweils eine andere Schlußwendung, auch wenn der sK jedesmal auf e6 landet." 11L/5P

ist "ein echter Petkow" (HMo) mit "Linienöffnung und Block bei S, und W setzt differenziert auf demselben Feld den Sprungbock zum Matt!" (MS)
"Ein phatastischer chinesischer Dreiklang!" (PGr)
HHS: "also nicht, wie suggeriert, der Leo als mattgebender Rückstein von d7 (oder h7 oder h3) aus, sondern nach höflicher Wegfreigabe dreimal als Deckungsgehilfe plaziert - ein achtungsgebietende Konstruktion (sicher gibt's auch noch einen pikanten Grund für Ke8...?) mit konsequentester Ausnutzung der Originalität, daß in China nur der Aufbau einer Batterie sich lohnt und nicht deren Abschuß..." Tja, das ist eine alte Chinesische Weisheit, oder Hüpferweisheit - auch Antibatterie genannt.
RobS: "Die Schlüssel öffnen die Linie für den Leo, der das dreimalige Matt auf d4 nach drei Blocks deckt - ein Juwel mit Märchensteinen!"
"Das läuft wie ein Uhrwerk; Petkow kommt anscheinend nie Sand ins Getriebe." (WoW)
Kam also sehr gut an. Auch die Wertung spricht für sich: 15L/5P/3.4/II.

Die im Diagramm vorhandene D-T-Batterie wird in beiden Varianten jeweils umgebaut, um anschließend sowohl den maskierenden Stein als auch die schachbietende Dame zu opfern. Der Autor reklamiert in diesem Zusammenhang " Erstdarstellung " während HAx all dies " meisterhaft " fand. Eine äußerlich sehr ähnliche Aufgabe PAPs als Vergleichsbeispiel: 1.Sa6 droht 2.Td6+ Ke5 3.Td5+ Ke6 4.De7+ K:d5 5.De6+ K:e6#, 1.- Te4 2.Te6+ K:e6 3.Dc6+ Kf7 4.Df6+ Ke8 5.De7+ T:e7#, 1.- Se4 2.Tc3+ Ke6 3.De7+ Kd5 4.T:d4+ K:d4 5.Dc5+ S:c5#, 1.- Le4 2.h8=S L:b4 3.Tc8+ Ke6 4.Te8+ Le7 5.Dc6+ L:c6# und 2.- Tc2 3.T:c2+ Ke6 4.Td2 nebst 5.Dc6+ L:c6#, 1.- L:b4 2.Df7+ K:c6 3.Dc7+ Kd5 4.De5+ Kc6 5.D:b5+ K:b5# 13L/3,5/III endwindow

(P. Petkov). Die thematische Verführung 1.d:c4? (droht 2.Dd5+ Kc7 3.Ta7+ Kb6 4.c5+ Kb5 5.c4+ L:c4#) zeigt eine Linienöffnung für Lf1, scheitert jedoch an 1.- S:b4! Am Rande sei auf die Zerstörung der S/T-Batterie und den Aufbau der maskierten S/D-Batterie hingewiesen. Nach dem Schlüssel 1.Ta7! mit Batterieverzicht droht 2.Dc7+ Kd5 3.d:c4+ K:c4 4.Se5+ Kd5 5.Ta5+ Lb5#. Schwarz verteidigt sich durch Schließen der Diagonale f1-a6, öffnet Weiß dafür jedoch jeweils eine Ersatzdiagonale, die nach den Massebeseitigungen auf e6 und c6 genutzt wird: 1.- c:d3 2.Lc8+ K:c6 3.Ld7+ Kd6 4.La4+ K:e6 5.Lb3+ S:b3# und 1.- e:d3 2.Le8+ K:e6 3.Ld7+ Kd6 4.Lh3+ K:c6 5.Lg2+ L:g2#. Im Zusammenhang mit der Mehrfachnutzung der wT/L-Batterie sprach der Autor vom Thema Rehm. Allgemein gefiel diese " klare Darbietung des komplexen Geschehens " (MOe) gut.
