Just for the record: Fritz Hoffmann, 2 f. (Both version of the last name
are very prevalent in Germany. For example, the LSD guy had only one :-)

Fritz HoFFmann was not yet born in the 1880s, when Fritz HoFmann composed chess problems. ;-)

> Fritz Hoffmann, 2 f
No. Apparently you mean Fritz Hoffmann (1932-2016).
But the author of this #3 (that was published in 1887!) is of course another Fritz Hofmann (with one 'f'!).

The pattern 1.A? b 2.C. 1...a!; 1.B? a 2.C. 1...b!; 1.C! a/b 2.B/A has also been called as "Kontrawechsel".
A recent example with reciprocal change is https://juliasfairies.com/problems/no-1224/

Just for the record: The LSD guy Albert Hofmann was Swiss, not German :-)

I think Hauke meant to write "prevalent in German", which should be correct [even by ultra-precise Swiss standards...]

Wait, there are a Fritz with one and one with two f, both composers?*
Ah bother, all Germans are named Fritz :-)
* No, not Ffritz. That would be a Brit. (insert "Feuerzangenbowle" shout-out)

Even german chess software is called "Fritz", but not Hof(f)mann ...

Don't forget Gustav Jonsson and Gustav von Broecker.

Francois Labelle's engine is named after the mathematician Carl Gustav Jacob Jacobi :)
