and the reference to wishful thinking yesterday, was an intentional and probable exaggeration but suitable for these issues

"... The main variation is 1.. Ng8" - i missed it

before my seeing others’ comments: My solution [arrived to through the 32-pixel, B&W, restartable-moving-pieces setting and “(?)”]: in view of the following possibility\s::::::
east-rook start forces still black king before west-rook check before north-knight to southeast before south-knight defense before east-pawn move before rook mate\ mates in less than four moves \\ ,,,,,,,,,,,,,,,,,,,,, it seems [ re-verification is intended later on and before seeing others’ comments] that white's rgthree starts

Another quote by the Polish science fiction author Stanisław Lem (1921-2006) whose centenary occurred a few days ago.
"For moral reasons I am an atheist — for moral reasons. I am of the opinion that you would recognize a creator by his creation, and the world appears to me to be put together in such a painful way that I prefer to believe that it was not created by anyone than to think that somebody created this intentionally." From Peter Engel, "An Interview With Stanislaw Lem": The Missouri Review, Volume VII, Number 2 (1984).

A Meredith featuring zugzwang. The key 1. Rg3 threatens 2. Rf8+. The main variation is 1.. Ng8 2. h5 (zugzwang) Nef6 3. Rgg7 (switchback, zugzwang) Nf~ 4. Rxh7#. On 2.. Ng7 3. Rf8 (zugzwang) Ng7~ 4. Rxg8#; 2.. Nc7, Nd6, Ngf6 3. Rf8(+) 4. Rxg8#. Side variations are 1.. Nd7, Ng4 2. exd7, Rxg4 3. Rf8+. Reprinted as No. 99 in the "Brunner-Buch": "Behinderung eines Springers durch einen anderen, angeregt durch eine Studie von Dr. A. Kraemer, Deutsches Wochenschach 1918."

Erich Anselm Brunner (* 11.12.1885 in Plauen, † 16.5.1938 in Zürich) German-Swiss composer, see wikipedia de, it, lv, ru, uk. "Erich Brunner composed around 600 strategic multimovers. The best of his problems were compiled by Moritz Henneberger and Hans Klüver, who completed Erich Brunner's selection, in "Erich Brunner - ein Künstler und Deuter des Schachproblems". The book can be downloaded from the internet as well as a list of errata, by Anton Baumann. Several themes are named after him or were researched by him, such as the Brunner-Turton, the Brunner-Dresdner, the Brunner-Plachutta, the Swiss theme, etc. For example: In Turton doubling a piece moves along a line (rank, file or diagonal), then a similarly-moving piece moves onto the same line in front of it, then this second piece moves again along this line, in the opposite direction to that of the first. The Brunner Turton is differentiated from the Loyd Turton by the fact that the first piece moved is of greater value than the second in Loyd-Turton, while in the former the two pieces are of equal value."

Günter Büsing commemorated Brunner's 125th anniversary in the 'Kalenderblatt' of 'Die Schwalbe' (December 2010): "Vor 125 Jahren wurde in Plauen im sächsischen Vogtland Erich Brunner (11.12.1885-16.05.1938) geboren, dessen Großvater aus der Schweiz als Schauspieler ans Braunschweiger Hoftheater gekommen war und dessen Vater in Plauen eine Gardinenfabrik betrieb. Das Schweizer Bürgerrecht hatte die Familie beibehalten, und Erich Brunner lebte zeitweise im Tessin (1918-28) und danach für einige Monate in Zürich, bevor er wieder nach Deutschland ging und seinen Wohnsitz in München nahm. Mit 21 veröffentlichte Brunner 1906 sein erstes Schachproblem. Im folgenden Jahr siedelte er nach Leipzig über, wo er dann in der Folge Komponisten wie Kohtz und Holzhausen kennenlernte, die ihn nachhaltig beeinflussten. Er komponierte rund 600 Probleme, eine 300 Aufgaben umfassende Auswahl davon wurde 1958 von Hans Klüver nach Vorarbeiten von M. Henneberger im Gedenkbuch 'Erich Brunner - Ein Künstler und Deuter des Schachproblems' publiziert. Intensiv hat er sich mit Turm-Manövern auseinandergesetzt. So hat er beispielsweise 1914 das Thema der Wechseltürme erstmals dargestellt."

Since the opening in October 2000, I had published online more than 6650 free chess problems. If you want more details, look at my chess figures pages.
