"How undisturbed, the sleep of the foolish."
Philip K. Dick (1928-1982) "Radio Free Albemuth," 1985.

Commendation. Not 1. Rd7? A (2. Qc4# C) Rc8! x; 1. Rf4? B (2. Qd3# D) Rh3! y. In the solution the try keys become the mating moves and the letters are permuted resembling the Banny and Hannelius themes from two-movers: 1. Qa6 (2. Qa1+ b2 3. Qxb2#) and now 1.. Rc8 x 2. Qd3+ D exd3 3. Rf4# B; 1.. Rh3 y 2. Qc4+ C dxc4 3. Rd7# A. Reprinted as No. 235 in Chlubna's "Michael Keller - Ein Meister der Schachkomposition" (1994). It turns out that Chlubna was the Judge and he explains why he granted "only" a Commendation: "Aber selbst wenn das Buchstabenschema neu ist, vermisse ich die von Keller und auch von Zirkwitz gewohnte strategische Tiefe. Zwei einfache Ablenkungen, zwei Damenopfer, alles ganz symmetrisch angelegt - dafür konnte ich mich trotz vieler positiver Löserstimmen nicht begeistern."

Michael Keller (* 31.5.1949 in Remscheid) German composer and Grandmaster, see wikipedia de, it, lv. "Michael Keller is specialized in two- and threemovers. The Keller paradox is a direct mover theme that requests that "White moves to a square just controlled (or controlled again) by Black."

Thorsten Zirkwitz (* 26.4.1965, † June 2016 in Berlin) German composer and International Master. "Thorsten Zirkwitz has mostly composed direct mates in collaboration (mainly with Keller) and has obtained many prizes. His personal webpage proposes a collection of his own problems classified by genres and themes, a list of chess problems links." See chesscomposers.blogspot.com for more. His obituary by Jörg Kuhlmann is to be found in "Die Schwalbe" (Heft 280, August 2016, p. 585 ff) available online.
