Richter H. Gruber "What a correction! Making the previously cooked R5 sound (hopefully), the author simultaneously improved it substantially : Instead of 'only' two, now we have three capture-free black circuits (Dd8, Ta8, Sb8). Everything is based on the need to capture sLc8, and it is achieved virtuously. It is not apparent that sTa8 and sSb8 have to move at all. This makes R5v clearly superior to a number of related tourney entries showing multiple switchbacks (cf. 3rd and 4th Hon. Men.). "
paul: Correction of P1000446 (2022-02-06)
Henrik Juel: There is a funny english error in the judge comment
He probably wanted to say that the author performed like a virtuoso, but wrote 'and it is achieved virtuously.', which has a completely different meaning (2022-02-06)
A.Buchanan: This is very impressive. (2022-02-07)

Richter H. Gruber: "The most impressive of the Echecs Einstein proofgames. Specific exchange of places of Lf1/Sg1, each moving once and capturing once. The circuit of wBg2 includes one pawn move, two moves and two captures of non-pawn pieces. In sum, most pieces are back on their initial game array squares. "
Joost de Heer: Bf1 and Sg1 should be swapped. (2002-09-15)

A.Buchanan: What's it called when a pawn promotes onto a square that another promoted pawn has already been captured from? Anti-Pronkin I think. (2018-12-19)

Joost de Heer: Solution 2 and 3 are the same after 6 moves.
As far as I know the length record for an exact move sequence with Haaner chess, P0007610 is longer but isn't exact. (2022-08-03)

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)

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.
