before my seeing comments: My solution [arrived to through the 32-pixel, B&W, restartable-moving-pieces setting]: in view of the possibility\s: mate with bishop from black’s weak side\ , to mate with east knight after west black-rook defense [or mate with bishop\ queen\ ] , white's kbeight starts

FIDE Album. Schweizerische Schachzeitung, 1970. Shown is the Mlynka theme of cyclically changed defense motives in the try 1. Nf8? (threat 2. Rc6#) e4! and the solution 1. Kb8! (threat 2. Be7#) both with the variations 1.. Rf7, R(x)f8, Qxd5 2. Nf7#, Qxf8#, Qxd5#. The black defenses in the try have the motives A-B-C with (A) pinning, (B) providing flight by capture, (C) guarding. In the solution these are cyclically changed to C-A-B.

Karol Mlynka (* 11.8.1944 in Kozárovce) Slovak composer and FIDE Master. "Karol Mlynka is a twomover and fairy composer. Juraj Lörinc summed it up on his website:

Teacher of Slovak and German languages. Known Slovak composer, he composes since 1961, inventor of Mlynka theme (cyclic change of defence motives of 3 defences in 2 phases) as well as many other original themes from the field of so called Slovak school. International judge FIDE since 1987 and FIDE master since 1990. In recent time he works well in Pat a Mat redaction, where he is editor for #3.

Karol Mlynka also invented the Supertransmuting King and has already composed many problems with this fairy piece. The definitions and some examples can be found also on Juraj Lörinc's website. Karol Mlynka's book "100 selected chess compositions" can be downloaded from selivanov.ru." Today's problem is listed as as No. 58 in the book "409 Selected Chess Compositions of Karol Mlynka" by Gabriel Török (also available online).
