Chebanenko's discovery 11.… d6 – d5

Vyacheslav Andreevich Tschebanenko (born February 19, 1942 in Syzran , † August 1997 , English Vyacheslav Chebanenko ) was a Russian chess player , coach and opening theorist .

He played only a few tournaments in his life, his best Elo rating was 2410. He became known primarily for his work as a coach in Moldova , where he full-time for the chess club of Chisinau worked. His protégés included the later grandmasters Viktor Gavrikov , Viktor Bologan , Viorel Iordăchescu , Dorian Rogozenco and Vladislav Nevednichy . He published very little, but primarily passed on his opening ideas to his students.

One of his most important contributions to opening theory is the move 4.… a7 – a6 in the Slavic Defense , which was made popular primarily by Viktor Bologan and which today has a permanent place in grandmaster practice.

Also from Tschebanenko comes the voluntary exchange 4. Bb5xc6 in the Sicilian Defense after moves 1. e2 – e4 c7 – c5 2. Ng1 – f3 Nb8 – c6 3. Bf1 – b5 g7 – g6. The following episode shows the depth of this thought: In 1986 Tschebanenko sent his student Michael Oratovsky to the Botvinnik chess school in Moscow, where he was sharply criticized for this voluntary exchange by world champion Garry Kasparov . However, Kasparov later realized that his judgment at the time was superficial, and only six years later he played that move himself (in Dortmund against Valeri Salow ).

Kasparov also attributes the following discoveries to Chebanenko:

• The renaissance of the Italian part with c2 – c3 and d2 – d3
• The move order 1. e2 – e4 d7 – d6 2. d2 – d4 Ng8 – f6 3. Nb1 – c3 c7 – c6 with the idea of ​​answering 4. Ng1 – f3 with Bc8 – g4 plus e7 – e6 and d6 – d5
• The move order 1. e2 – e4 d7 – d6 2. d2 – d4 Ng8 – f6 3. Nb1 – c3 e7 – e5, without fear of exchanging on e5 with a subsequent queen exchange and loss of castling
• The innovation 11.… d6 – d5 from the first game of the 1971 final candidate match between Bobby Fischer and Tigran Petrosjan , which White invites to the pawn fork 12. e4xd5 (see example diagram). Tschebanenko had previously sent his analyzes of this variant to the host of the 1971 semi- final between Petrosyan and Viktor Korchnoj. These were contained in a sealed envelope to be given to the winner of the competition.

Chebanenko died of a heart attack in August 1997 .
