let's look at Peter's #2!

Seasons greetings everyone!

This is a particularly beautiful problem, made in the day(I believe!) when twinning was particularly in vogue(perhaps the end of the period...) So the first question: Is the composer named Peter or Fritz? (Is the latter a nickname?) and does his last name officially end with one or two "n"s?

Peter Hoffman
1PR. Die Schwalbe
(= 13+3 )

#2 B.f3S to c6

A.Qe8 f6,f5,fe,fg 2.Qa4,Bh5,Qxe6,Qxg6
B.Qf8 2.Qb4,Qxf5,Qxf4,Qf3

changed pickaninny with a 5th change for unguarding e5 the right way.
1.Is hiding the Q diagonally behind the bP the most common way of generating a Pickaninny?
2.what do you think of the pinning mechanism?!
3.this is a zugzwang-do the few non-thematic variation duals bother you?
4.the W battery only generates one mate, but the rook is employed to protect the K-your thoughts on this construction?

See on the (electronic) book of Erik Zierke "Der Reiz des Ungewöhnlichen – Ausgewählte Schachaufgaben von Peter Hoffmann." The author is quite critical of that 2-mover that is given on page 7. He says (in my express translation...)
The (B01) shows four changed mates after a Pickaninny. The judge said that "previous presentations had constructive weaknesses, here the task is shown brilliantly". Openly: My understanding of "brilliant" means at least a performance without twinning! Second, the way how the twins are given is not uniform as on f3 the knight not only blocks the queen (as on c6) but additionally protects the square g5 (relevant for the changed mate after fxe6). And third, the changed mate after 1... f6 is only a pseudo-change.

So, here you have already some answers for your questions by Erik Zierke. My opinion is more positive, I think the task is so difficult that the presentation is amazingly clean and harmonious.

<mode=bitching> My personal experience is: To get an applause from Erik Zierke,
you have to press a gun against his temple first :-)</mode>

The e-book cited, contains some outstanding problem of Peter Hoffman. Great composer.

It is Peter Hoffmann from Braunschweig. Not to be confused with Fritz Hoffmann from Weißenfels.

Martin Hoffmann is from Zürich. Which can easily be seen in the Schweizerische Schachzeitung.

It's not THAT rare a name, such accidents happen.
(Positively scary it gets when I tell you that in the
German USENET jokes newsgroup there were even four to
five Hoffmanns posting regularly :-)
