Black has an active position. How does he develop the initiative? White's pieces are well placed but Black can destroy the coordination of White's pieces with 25...b5!.

Black needs to get the rook off the long diagonal but 16...Rac8 would be a serious mistake. Black's plan is to play on the queenside and he needs both rooks present on that side of the board. If 16...Rac8, then the rook on f8 would not have room to move.
16...Rab8! 17.0-0 Rfc8 18.f4 Kf8 19.e4 Na5 20.c3 Nc4.
16...Rab8! 17.0-0 Rfc8 18.f4 Kf8 19.e4 Na5 20.c3 Nc4.

πΉ Mikhail Botvinnik
πΉ Soviet and Russian chess grandmaster
πΉ 6th World Chess Champion
π° Mikhail Moiseyevich Botvinnik was a Soviet and Russian chess grandmaster and World Chess Champion for most of 1948 to 1963.
πFull name: Mikhail Moiseyevich Botvinnik
πCountry: Soviet Union
πBorn:
π»August 17, 1911
π»Kuokkala, Grand Duchy of Finland, Russian Empire
πDied:
π»May 5, 1995 (aged 83)
π»Moscow, Russia
πTitle: Grandmaster
πWorld Champion:
π»1948β1957
π»1958β1960
π»1961β1963
πPeak rating 2660 (January 1971)
π°Mikhail Moiseevich Botvinnik was born in St Petersburg, Russia in 1911. He learned to play chess at the age of 12. An electrical engineer by training, he was the first Russian to hold the World Championship title after he won the 1948 tournament following the death of Alexander Alekhine. He held on to the world title until his defeat by Petrosian in 1963, except for two occasions when he lost the title for one year, to Smyslov (1957 - 1958) and Tal (1960 - 1961). Botvinnik was very serious about chess and never played for fun.
π°After his defeat to Petrosian he trained other Soviet players and devised a training programme. He advocated practicing with strong players, studying master games, publicizing analysis to be criticized by others, learning to handle the clock to avoid time trouble and to concentrate in spite of disturbances. Although he was a non-smoker, he often practiced with heavy smokers to practice his ability to concentrate in adverse situations. He also stressed the importance of regular physical activity to maintain fitness. In 1970 he gave up playing in order to concentrate on the development of chess computers.
π°Botvinnik served as a consultant to Soviet computer chess developers who developed an early program at ITEP (Moscow Institute for Theoretical and Experimental Physics) which won a correspondence chess match against a Stanford University chess program led by John McCarthy in 1967. Later he advised the team that created the chess prorgram Kaissa at Moscowβs Institute for Control Science.
