Dreifachsetzung des Umnov-Themas (Weiß setzt auf dem Feld matt, das Schwarz soeben verlassen hat). Dreimal thematischer "Treffpunkt" auf dem Feld d5 mit Selbstfesselung der Themafigur, hat gefallen (KHS)!

Selbstplagiat!
Gunter Jordan: Er kann es halt nicht lassen! Genau die gleiche Aufgabe veröffentlichte Pankratiev in Springaren, Heft 137, 09/2015, Nr. 13442. Kurioserweise dort mit dem Ko-Autor M. Gershinski. (2017-02-27)
Olaf Jenkner: Was hat der Erfinder von Unix damit zu tun?
Zwar hat er die ersten Endspieldatenbanken geschaffen, aber im Hilfsmattbereich ist er doch ein unbeschriebenes Blatt. (2017-02-27)
Gunter Jordan: Ich habe noch einmal in der Ursprungsquelle (SuperProblem) nachgesehen. Der Ko-Autor ist nicht Ken Thompnon, sondern Gerschinski (wie auch beim Selbstplagiat). Ich habe K. Thompson als Autor gelöscht, bekomme aber Gerschinski nicht in die Datenbank hinein, der wird so komisch geschrieben. Vielleicht kann jemand helfen? (2022-01-03)

Mustermatt.
In Lösung b) zweimal Beseitigung hinderlicher weißer Masse: Der wBf2 wird beseitigt, um den weißen Läufer aus seinem Käfig zu lassen. Der wBg3 wird beseitigt, damit dort ein schwarzer Bauer im Mattbild blocken kann. Tempoverlust des weißen Königs im zweiten Zuge. Umnow-Effekte bei Schwarz in den Zügen 4 bis 6 und bei Weiß in den Zügen 5 und 6 bei Weiß.

18731 (Hartmut Brozus). 1.Ke5 e4 2.Kd4 e:d5 3.Le5 d6 4.Kd5 d7 5.Kd6 d8=D#(IM). „Der schwarze König macht seinem Läufer Platz zum Block und kehrt auf sein Ausgangsfeld zurück, während Weiß seinen Bauern zur Umwandlung mit Idealmatt führt. Recht leicht zu lösen – nur über den richtigen schwarzen Weg zum Erfolg musste man kurz nachdenken.“ (FRd) „Der Klasinc mit Rundlauf des thematischen Königs findet hier eine Elementardarstellung mit Exzelsiormarsch, die ein wenig unter der mangelnden Schwierigkeit leidet.“ (MRit) „Diese Aufgabe habe ich aus Versehen gelöst, als ich verzweifelt versucht habe, eine ähnliche Mattstellung in 18731 zu erreichen. Lustiger Rundmarsch des schwarzen Königs.“ (JS) Auch KHS gefällt das Stück gut.

On this site - https://streathambrixtonchess.blogspot.com/2007/01/london-transport-chess-puzzle-ii_13.html?m=1- there is a small note that compares the work of the London Underground in "rush hour" with the solution in G. Popov's eight-move.

London Transport Chess Puzzle II

Five O'Clock inLondon, and a crammed crush-hour underground on the tube. The doors at each station open, the mass shift a touch sideways, each in tiny steps; and - yet another sardine leaps in. Curses under breath, shuffles almost kicks, dagger-stares, and sweat. The heat, the constriction of space. The needless pressure of time, the will to be some place. so what? Well - I was reminded of that inevitable squish by this chess puzzle, for fairly obvious reasons. It's composed by Grigory Popov, and white is to play and mate in eight. It was agony going through it. . . but later, I saw the funny side.
# posted by Tom Chivers

Indeed, the first steps of the solution resemble the behavior of passengers in crowded transport - . Passengers pack in and another " sardine " jumps into the car. The author of the problem invited Valentin Viktorovich Leader to give his version of events, covering all 8 moves of the solution . And here is his new novella-

Parliamentary passion

(diagram)

The Queen (Fd1) has long resented the presence within the walls of parliament of Mr. Krashodin (Krh1), who is steeped in corruption and linked to organized crime. At the request to deprive him of parliamentary immunity (black bishop g1), the queen was demanded a concession: to introduce into the government for the post of prime minister (field e1) a protege of parliament, the young and ambitious Mr. C * (Ch4). The Queen agreed, but C * linked his future appointment with giving him the opportunity to carry out reshuffles in the cabinet, relating, in particular, to the heads of such ministries as the ministries of finance (field b 1), defense (c1) and culture (done). After long four-day consultations, the Minister of Finance (Lb1) was dismissed in the field of his usual activities - Chairman of the Board of the Bank (1.La1!), Kr.s1, who once headed the cabinet, received the portfolio of the Minister of Finance (2.Kr. b 1), the queen, who felt in her place in the ministry of culture, became the minister of defense (!) (3.Fs1), and the prime minister became the minister of culture (4.Ld1). Meanwhile, members of the opposition parties in parliament (pp. b 5, d 5, f6) took a number of steps aimed at disrupting the consultations, but at the end of the fourth day of negotiations they were blocked. In order not to create a stalemate, on the morning of the fifth day C* was appointed prime minister (5.Ce1); on the same day Mr. Krashodin's parliamentary immunity was terminated (5…?f2 6.?:f2+). Attempts by some oppositionists to save the latter, however, costing the resignation of the Minister of Culture, failed, and the queen, with the support of the new prime minister, issued a decree on the arrest of Mr. Krashodin (6 ... g1 7.L:g1 + hg 8.F:g1x). Cleanly done!
James Malcom: With the story, the problem is even more humorous. (2022-07-14)
A.Buchanan: I can confirm the nature of the London tube experience. Cool problem - thanks for posting with the entertaining story, Story (2022-07-15)
A.Buchanan: Is it possible to push this one move further by something like 8/8/p2p1p2/8/Pp5B/1PpPpP2/R1P1P1pp/1BKQR1bk (2022-07-15)
James Malcom: Always happy to remind you of your traumatic subway systems. :-)

And, alas, cooked in 5: 1. Bxf6 a5 2. Bd4 d5 3. Bxe3 d4 4. Rxg1+ hxg1=Q 5. Qxg1# (2022-07-15)
A.Buchanan: Well I’ll still have a play around with it. I was almost certain that the proposal would be cooked, it was just intended as a starting point.
