Hello:

Old problem from 1750!

https://yacpdb.org/#422730
https://pdb.dieschwalbe.de/P1308396

The original source is Sopra il Giuoco degli Scacchi, Osservazioni Pratiche d'Anonimo Autore Modenese by Domenico Ercole del Rio. «d'Anonimo Autore» means 'by anonymous author' or 'by unknown author':

https://books.google.es/books?id=shBZAA ... &q&f=false

The problem is found at pages 85 and 86, 'Second Part. About Endgames of the Games. First Chapter. Paragraph XI' (Parte Seconda. Delle Finite de' Giuochi. Capitolo Primo. Paragrafo XI), with a typo correction from page 85:

Proposed solution in algebraic notation:

1.- Bf3+, Kh3; 2.- Bf3+, Kg1; 3.- Bh1, Kxh1; 4.- Kf1, d5; 5.- exd5, e4; 6.- d6, e3; 7.- d7, e2+; 8.- Kxe2, Kg2 {or Kg1}; 9.- d8=Q, h1=Q. White checkmates in few moves. The author did not provide the final moves.

The position after 3.- ..., Kxh1 is a checkmate in 14 moves according to 6-man EGTB, with 4.- Kf1 being the only winning move.

------------------------

There are similar problems based in the key moves of the problem from 1750, for example:

Jean Louis Preti, 1856:
https://yacpdb.org/#545727
https://pdb.dieschwalbe.de/P1392985

Louis van Vliet, 1895:
https://yacpdb.org/#287564
https://pdb.dieschwalbe.de/P1279142

A more complicated problem that features a similar zugzwang idea Bh1, Kxh1; Kf2 in one of its variants is:

Alexey Alexeyevich Troitsky, 1930:
https://www.yacpdb.org/#281057
https://pdb.dieschwalbe.de/P1373950
