Rudolf Heinrich Willmers (31-10-1821 - 24-08-1878) Austrian composer


Rudolf Heinrich Willmers was widely known as a brilliant player - the trill was his specialty - and composer... for the piano (source), but he also composed chess problems. "Musicians and Chess" reports the following anecdote:
While playing Schumann's 'Carnival' in a piano recital in Copenhagen, Willmers stopped suddenly, wrote on his cuff, and then continued. He explained afterwards that he had been struggling for a week to solve a difficult problem when the solution came to him in a flash. 'I had to jot it down to get it out of my head and let me concentrate entirely on my playing.
Which, of course, seems completely natural to chess solvers or composers.

Kārlis Bētiņš (27-10-1867 - 28-03-1943) Latvian composer

Karl Behting (Deutsches Wochenschach, 5 January 1908)
[Wikipedia]


Kārlis Karlovich Bētiņš (Karlis Betins, Karl Behting) was a chess master and composer of studies, as was his brother Jānis. We remind our readers of the existing brochure by John Beasley about the Behting brothers which can be read on John Beasley's site (BESN special number 52).

Recently John Nunn published on ChessBase some analyses related with Karl Behting's draw study Baltische Schachblätter 1908 which, with the help of a seven-man database, was proved correct.

Friedrich Martin Palitzsch (25-10-1889 - 02-04-1932) German composer

Friedrich Palitzsch was a founding theoretician of the German Logical school. He created, explored and promoted the Dresden theme: A good defence to a threat is eliminated (usually by means of a foreplan) and a bad defence by a different piece (not previously available) is introduced.
In 1917 he wrote "Die Ablenkung, das Element der indirekten Kombination" which exposed the concepts of the neo-German school.

Михаил Михайлович Барулин (19-10-1897 - 23-05-1943) Russian composer (Mikhail Mikhailovich Barulin)

Mikhail Barulin
[Grigory Popov]

Mikhail Barulin was the editor of the problem section of the Soviet magazine "64" from 1935 to 1941 and of "Shakhmatny v SSSR" from 1938 to 1941. He is considered as one of the creators of the modern twomover, which he made more popular thanks to his articles published in worldwide magazines. He has popularized white tries in twomovers since 1927.

Vladimir Tyapkin recalled in details on Mat Plus forum in January 2010 the circumstances in which M. Barulin wrote the article "Chaos in thinking" (Сумбур в мыслях) in Chess in USSR №7, 1936, as a reply to an article written by M.Botvinnik and L.Spokoiny. Barulin's scanned article was made available by Vladimir:
1st part.
2nd part.
Sergey N. Tkachenko also wrote about this controversial topic on chesspro.ru, reproducing both articles in text and placing the two articles in the larger context of the relation between chess players and chess composition, in the USSR and without.

František Dedrle
[encyklopedie.brna.cz]

John D. Beasley presented this composer in BESN Special Issue 31 where he also gave a few of his studies with commented solution and which can be read with pleasure:
"The Moravian composer and analyst František Dedrle (1878- 1957) was an all-rounder whose interests embraced problems, studies, and endgame theory. Problemists know him from "Böhmische Schachminiaturen" (1922), from his introduction (in English) to A. C. White's book "Bohemian Garnets" on the problems of Miroslav Havel (1923), and from his trilingual book "Echo" (1927). His writings on the endgame included an article on Drtina's theory of critical squares in pawn endings (1919) and a book "Studie" (1925) containing 150 studies with detailed analysis (...)"
He was also an International Judge.
Read "Böhmische Schachminiaturen" here.
