- "It is one thing to show a man that he is in an error, and another to put him in possession of truth."
John Locke (1632-1704) Essay Concerning Human Understanding (1690), IV, 7, 11.
A Bohemian tanagra with echo model mates. Black threatens to defend by 1.. Bd6 2.. Bh2. Thus 1. Rd2 with several threats, on 1.. Bg7, Bh6 the echo 2. Rd1+, Rh5+ Kh2, Kg1 3. RxB zugzwang 3...

"Der frühe Fünfsteiner ist typisch für die böhmische Materialbeherrschung und zaubert bei sprödem Material einen sechsfachen L-Abfang mit anschließenden Modellmatts aufs Brett." (Günter Büsing, Die Schwalbe, 2008). Often reprinted.
What is a "model mate"? This is explained in a short video on YouTube:
Johannes Quack (* 3.10.1959 in Anrath) an organist, church musician, and problemist from Oberwinter (see wikipedia de) publishes the channel "Mustermatt" on YouTube dedicated to all genres of problem chess. There are ~200 videos and each week a new one is created. They are mostly in German, but No. 179 is in English explaining the model mate (which is "Mustermatt" in German).
Miroslav Havel (* 7.11.1881 in Teplice, † 8.7.1958 in Prague) Czech composer and Grandmaster, see wikipedia de, fr, it, lv, ru. "Miroslav Havel (Miroslav Košťál) composed Bohemian problems with a high degree of mastery and artistry. You can judge by yourself by the selfmate reproduced on wikipedia de. He edited the chess column of newspaper "Čas" (1920-1923) and was honoured by the publication of 500 of his problems in "Bohemian Garnets" in the White Christmas Series. He also wrote "České granáty" (1943)." Both books are available online.
From the "Kalenderblatt" in "Die Schwalbe," August 2008 [There also today's problem is reprinted with the comment quoted above.]: "Dr. Miroslav Kostal, besser bekannt unter seinem Pseudonym Miroslav Havel (7.11.1881-8.7.1958) ist wohl bis heute der bekannteste Vertreter der böhmischen Problemschule. 1923 widmete A. C. White ihm in seiner Christmas-Serie den Band "Bohemian Garnets." Unter dem Titel "Ceske granaty'" erschienen 1936 und 1943 weitere Aufgabensammlungen dieses böhmischen Klassikers."
Since the opening in October 2000, I had published online more than 6650 free chess problems. If you want more details, look at my chess figures pages.
