That's 27 years. You could have checked the first game and the last game and seen if there was an error... or something. That is, if it ever did say 1865 to 1992.

A) 1...h1=Q 2. Bxg5#.

<For Minckwitz chess has not the slightest to do with his mental illness, which in my opinion must be ascribed to “primary hallucinatory madness” <”primare halluzinatorische Verrucktheit”>. Minckwitz was unfortunately placed, such that he was at great risk of mental illness. Of his father, a professor at Leipzig University, it is recounted (not as a funny story, but as truth) that he used to say in his lectures: “There are only three great German writers: Schiller, Goethe, and the third modesty forbids me to name.” <This reads exactly like Janowski’s alleged statement about the great chessmasters of his own time – perhaps Janowski's quote is spurious?> This was the era in which Paul Lindau went eagerly on the hunt for Sunday poets <Sonntagdichtern> and, when he found one, tore him to pieces to the delight of the public. He came upon Minckwitz’s epic “The War for Liberation” <”Die Befreiungskriege”> and quoted the following verse describing the Battle of Leipzig:

Napoleon was yellow like a pickled egg <Solei>, Anyone who saw him knew good health he must beg.

<Napoleon war gelb wie ein Solei, Man sah ihm an, dass ihm nicht wohl sei.>

<Obviously I warped the meaning for the sake of getting a rhyme.>

Once, when his opponent (Wilfried Paulsen) overstepped the time limit, Minckwitz wanted to keep playing and eventually lost "by the usual collapse." The tournament director solomonically ruled the game a loss for both players.

The eulogy in Checkmate concludes discreetly by saying that "some years ago it became necessary to refuse his entry to all public tournaments" - which means, I assume, that he's completely loony.

Minckwitz wrote a book called Humor in Chess, which looks like it might be interesting (the chapters are titled things like 'A terrible vision of H. Lehner'/'Sufferings and joys of a problem composer') but available only in German.

The first anecdote about Minckwitz Sr. claiming to be the greatest German poet together with Von Goethe and Schiller, is most likely apocryphal and this kind of saying has been assigned to others before (e. g. Konrad Büchell). Dr. Ahrens devotes a lot of attention to this part and points e. g. out that Minckwitz Sr. was a great admirer of Count August von Platen-Hallermünde and translated his odes into greek (so he would rather be Minckwitz's Nr. 3). Apparently, the only actual case of this form of joke (with two people instead of three) was that of Dr. Tarrasch saying that there were only two chessmasters - and the other one was living in New York.
