Hermann Weißauer (born October 4, 1920 in Freising ; † August 2, 2014 in Ludwigshafen am Rhein ) was a German chess composer and journalist . The Weißauer Bahnung is named after him.

Life

Weißauer was the son of an elementary school teacher, graduated from the humanistic Dom-Gymnasium Freising in 1939 and began to study chemistry in Munich . In 1941, however, he was called up and was taken prisoner of war in Norway at the end of World War II. In 1946 he took up his chemistry studies again and received his doctorate in 1952 at the Ludwig Maximilians University in Munich. From 1953 he worked at BASF in the color research . Weissauer secured a number of patents for BASF, including an American patent for water-soluble anthraquinone dyes and their production together with a colleague .

Weissauer was an enthusiastic chess player all his life. Since 1953 he was a member of the Ludwigshafen chess club in 1912 and took part in the finals of the German team championship with this club in 1956 and 1958. In 1990, on his 70th birthday, he received the Palatinate Chess Federation's plate of honor. He was particularly interested in chess composition . He composed about 500 chess problems, mainly new German three-move. In 1978 he founded the German Problem Solving Championships, a tournament in solving chess problems that he directed for a long time. For many years from 1979, Weißauer edited the problem section of the chess magazine Rochade Europa . He has been international arbitrator for chess composition since 1987 and was appointed Honorary Master of Chess Composition by the World Federation for Chess Composition ( WFCC ) in 2012 . In May 2002 the German Chess Federation expressed its gratitude and recognition in the form of an honorary certificate. His services were also recognized with an honorary membership in the Schwalbe and in 2010 with the honor plate of the German Chess Federation "in recognition of his achievements and his commitment to problem chess". A popular line combination motif bears his name: the Weißauer Bahnung; Other topics that Weißauer dealt with were changing batteries and miniature “four-spring mats” .

The Weißauer-Bahnung

It is about a black-and-white pathway : a black long-strider removes obstructive white matter and then paves the way for a white long-strider on the line that has become anti- critical (in the sense of Hans Klüver : anti-metacritical).

The main problem of the Weißauer-Bahnung:

Mate in 3 moves

Template: checkerboard / maintenance / new

The task shows Weißauer's development in two positions, i.e. two times: 1. Nb3 would already be mate if white pawn c5 didn't move the cover line of white rook c8 to c4 and c3. The same applies to 1. Qxg7, here the white pawn d5 interferes, blocking the line of action of white bishop a8 after e4.

Solution: 1. Kf8! 2. Kxg7 and 3. Bf6 threaten to mate. The defense 1.… Rxc5 (with the idea of ​​2.… Rxc8) also has a damaging effect: The disturbing white mass on c5 disappears. But now the black rook blocks the line of action of Rc8. With 2. Nc2 + he is forced to pave the way , that is, he crosses the point c3 so that the cover line of the white rook is extended to c3: 2.… Rxc2 3. Nb3 mate and 2.… dxc2 3. Qxe3 mate. 1.… Bxd5 works analogously (idea: 2. Kxg7 Bxa8) 2. Nf3 + Bxf3 3. Qxg7 mate .

The train 2. ... TxC2 (or Bxf3) is anti critical because he (would exceed the result of opening a line of action the critical field (c3 and e4) mean during a critical train exceeding the critical field with the sequence of line blocking, as in Indian ). According to Hans Klüver's terminology, this is a metacritical , more precisely: anti- metacritical move, because the barrier itself crosses the critical field, so there is actually no point of intersection (unlike the Indian or Turton ).

A further development of this motif was the Weißauer- Pachl- Bahnung, shown for the first time in 2006 , which dispenses with the white barrier stone (i.e. the white mass to be removed).
