Cycle ABC-BCA-CAB

Judge Julia Vysotska (The Problemist, November 2018, p.510-513): "A pawn, seemingly destined to block its own king, suddenly leaves there to promote into three different hoppers, and to jump far away! A complete cycle of 2 promoted pieces (promotes and blocks, promotes and mates) and a blocked black hurdle. All promotions appear on the first moves, with nice anticipatory blocks of the hurdle by the black promoted piece, and mates by the white promoted piece. A pity that the BHb4 is needed only for BH promotion in two first solutions, while the NH and RH are in a superior position blocking the bK when not playing. An interesting issue is the bBd6. Technically, it could be replaced with a bP, but the author wanted the total number of black pawns and black fairy pieces not to exceed 8. I wouldn’t support such an approach, seeing no logic in it, but respect the author’s choice."

Comments of solvers: "Cycle (as expected!) of promoted piece types. The somewhat limited mobility of these pieces facilitates a neat construction with relatively few blocks. A good idea well set." (CJF), "Complete 3-cycle of white promotee, black promotee and piece blocked by move thereof. Not difficult but again enjoyable; hope'VK will compose more in this style." (CCL), "Not this month, though!" (SE), "Pleasing patterns" (FM).

19308 (Fadil Abdurahmanovic & Mirko Degenkolbe). I. 1.T:c8+! d:c8S!! 2.De6 Db5# (MM), II. 1.D:e8+! d:e8D!! 2.Ld6 Sb6#. „Der Hinweis im Vorspann war sehr hilfreich“ (JS), denn wir sehen hier „eine Art Wiederauferstehung.“ (ES) „Witziges Spiel und einmal Mustermatt – was will man mehr?“ (JS) „Doppelphönix in Meredith-Form, beachtlich!“ (BK) „Blocks von schwarzer Dame und schwarzem Läufer erlauben nach Phönix-Umwandlung Dame /Springer-Matts“ (JB), „ein spektakuläres zweifaches Wiedergeburtsdrama.“ (VZ) „Schlag weißer Steine, die danach gleich wieder durch Bauernumwandlung auferstehen, und das nur, damit der lästige weiße Bauer zur Öffnung der Diagonale verschwindet. Nicht ganz einheitlich in der Motivation der schwarzen Züge, aber effektvoll.“ (FRd) „Damit der weiße Bauer die Linie von e8 in Richtung c6 bis b5 räumen kann, wird ihm ein Flügel verleihender Energy-Drink verabreicht. Die Verbindung des immer wieder gerne gesehenen Phönix- Motivs mit einem Zilahi, die mit schwarzem Themabauern nicht unbedingt leichter von der Hand geht (P0551679), wurde in Vergleichsaufgabe P1004692 mit Linienöffnungen für die Blocksteine in Verbindung mit weißer Zugnot begründet.“ (MRit) „Elegante Phönix-Einleitungen zu dem Zweck, der weißen Ursprungsdame in Lösung I. die Mattlinie, in Lösung II. der weißen Phönix-Dame die Deckungslinie nach c6 zu öffnen. Lösung I. mündet nach schwarzer Damen-Entfesselung und Block in ein Mustermatt, Lösung II. nach schwarzer Läufer-Verstellung und Block nicht. Insgesamt aber sehr schön.“ (HJä) „Schwarze Opfer, Tschumakow-Thema, Zilahi, weiße Umwandlung, Phönix, Onkoud- 50-Thema. Strategisch sehr reichhaltig. Gehört auch in den Preisbericht. Prima.“ (KHS)

solution 1.cxd6ep+ Sxc3 2.d7 Lxg7#
Last move was not c4xd3 or e4xd3 (on a light square), because the missing white man is the dark-squared [Lc1], so it was d7-d5, legitimizing the ep key (2021-10-03)
A.Buchanan: Sound + lighter + W2 becomes sole viable tempo move (with 10 other White pieces able to move). (2021-10-04)
