H.F.L. Meyer's Great Problem
I came across a very interesting and unusual problem by H.F.L. Meyer in a Polish chess magazine and decided to share it with you, but first let me introduce the author shortly:
Heinrich Friedrich Ludwig Meyer (1839-1928) was one of the greatest German problemists and a chess author. His most famous book is 'A Complete Guide to the Game of Chess: From the Alphabet to the Solution and Construction of Problems' (1882), now reprinted in Forgotten Books series.
I hope that you liked the puzzles. You can find more Meyer's problems in his books and online e.g. here.
