Classic Study by K A L Kubbel
This study returns to the classic period of great studies by another of the great Soviet composers. This one is by K A L Kubbel, which is how he is always known, though he changed his name to Leonid Ivanovich after the 1917 revolution. He was a chemical engineer by profession whose two brothers were also chess players. Arvid Kubbel was executed in 1938 during the Stalin purges, while Leonid and his brother both died in the seige of Leningrad, as did another great endgame composer A A Troitzky. Kubbel was fifty.
This composition was a late one composed in 1940, an illustration of what can be achieved with limited material.
