Leonid Kubbel

Leonid Kubbel ( Russian Леонид Иванович Куббель , originally Karl Arthur Leonid Kubbel * December 25, 1891 . Jul / 6. January  1892 greg. In St. Petersburg ; † 18th April 1942 in Leningrad ) was a Russian chess composer .

biography

Leonid Kubbel was a chemical engineer by profession. His two brothers also dealt with chess composition. Arwid Kubbel published around 500 compositions of the Bohemian School , mainly Dreizüger. The younger Jewgeni Kubbel (* October 23, 1894; † 1942) wrote over 150 tasks, mainly two-move. Leonid Kubbel and his brother Yevgeny died during the Leningrad blockade and were buried with other blockade victims in a mass grave. Arwid was arrested on November 21, 1937. The arrest was kept secret and later spread the false report that he in a Siberian gulag in nephritis had died. In fact, he was shot on January 11, 1938, later rehabilitated during the thaw .

The ancestors of the Kubbels were Germans.

Chess composition

Kubbel composed about 2300 chess problems (mostly three-move) and more than 500 studies . Over 500 compositions received awards, including 120 first prizes. Kubbel led various chess columns and influenced with his views lines of development in chess composition.

According to his book 150 Endgame Studies at the age of 13 , he created his first study in 1904. At the beginning, Kubbel took positions of the Old German and Bohemian Schools , but in the late 1920s he came to the conclusion that many combinations could not be artistically represented with Mustermatt. Until 1911 he mainly composed chess problems. Löwenfisch considered them “perfect artistic products”. This was followed by an interruption of three years, and Kubbel did not compose again until 1914. From 1918 he composed almost exclusively studies. However, they did not appear until 1921 in "Listok Petrogubkommuny". Kubbel dealt with ideas of the new German school . Löwenfisch praised the structure, economy and purity of Kubbel's studies, who, in Löwenfisch's opinion, had developed his own style.

White to move wins

Template: checkerboard / maintenance / new


At first sight it seems impossible to win this game in view of the black pawn on a3. However, white can bring a surprising matte motif into play.

Solution:

1. Nb8 – c6! (threatens Nc6 – b4 + with blocking the a-pawn)
1.… Kd5xc6 (if 1.… a2 2. Nb4 + and Nxa2)
2. Bh4 – f6 Kc6 – d5 (2.… Kc5 3. Be7 +)
3. d2 – d3 ! a3 – a2
4. c2 – c4 + Kd5 – c5 (4.… bxc3 ep 5. Bxc3)
5. Ka6 – b7! a2 – a1D (after 5.… Kd6 or Kb4 White can stop the a-pawn with 6. Bxd4)
6. Bf6 – e7 pattern mate

The introductory knight sacrifice serves only to gain a speed . Immediate 1. Bf6 would be after 1.… a2! too slow. Due to the sacrifice, the cover of the c6-square is lost, which makes the mate final appear particularly surprising; the white king actually has time to restore it on move 5.
