- A Bohemian problem. The key should be by wRc1 as it is out of play. To move it on the c-file does not work, e.g., 1. Rc3? Kg4. So we move it on the first rank to g1. This carries no threat but creates black zugzwang which leads to several model mates. 1.. Kg4, f5, Re6-e8, Rf5, Rg5, Re4, Re3-e1 2. Nf5+, Qf3, Nf5+, Bh6+ (Nxf5+), Be5+, Nf5+, Be3#. For the solver the zugzwang is quite unexpected and for a while she may look in vain for a threat.
Čeněk Kainer (* 22.5.1883 in Holešov, † 22.3.1945 in Podhradní Lhota) Czech composer, see wikipedia lv. "C. Kainer, einer der würdigsten Vertreter der böhmischen Kompositionsschule, verdient, auch unseren Problemfreunden vorgestellt zu werden." (Schweizerische Schachzeitung, July 1954, p. 122) His obituary ("Odchod valašského učitele-úloháře") was published in Šach, 1945, p. 115 (available from the site "Chess Problem Links" of Václav Kotěšovec). Collections of Kainer's problems were published in Vol. 2 of Miroslav Soukup's "Šachové umění" under the title "Čeněk Kainer: Valašské dumky," Praha, 1937 (with a preface of Miroslav Havel) and in Vol. 8 of "Galerie československých skladatelů," Praha 1971, edited by Ilja Mikan (both books are also available from "Chess Problem Links"). Today's problem appears as No. 228 in the latter.
