☑️ #about_Bronstein
▪️ David Bronstein
▪️ Soviet Chess Grandmaster
▪️ Chess Author
🔰 David Bronstein, who died on Tuesday aged 82, was a leading Soviet chess grandmaster and writer; like Viktor Korchnoi, he was often described as the greatest player never to have won a world championship.
🔘 Full name: David Ionovich Bronstein
🔘 Country: Soviet Union
🔘 Born: February 19, 1924
Bila Tserkva, Ukrainian SSR, Soviet Union
🔘 Died: December 5, 2006 (aged 82)
Minsk, Belarus
🔘 Title: Grandmaster (1950)
🔘 Peak rating: 2595 (May 1974)
🔰 Some great chess players take a scientific approach to the game, delving into the intricacies of each position in a search for mathematical precision; others see it as an intellectual sport, with each player straining to overcome the opponent by force of will; but, among all the top grandmasters of the second half of the 20th century, David Bronstein was perhaps the one true chess artist.
🔰 In the opinion of many, he was the finest player who never won the world championship (though he came very close when he tied a match 12-12 with Mikhail Botvinnik in 1951); in the opinion of others, he was quite simply the most creative player of all.
🔰 He also wrote a number of highly individualistic chess books, of which his Mezhdunarodny Turnir Grossmeisterov account of the 1953 candidates' tournament in Zurich (published in 1956 and translated into English as The Chess Struggle in Practice, 1978) stands out as maybe the finest tournament book ever.
♦️ A memorable game by Bronstein from URS Championship(1945) which named "Scotch on the Rocks" in chessgames.com site!! 👇
🔸 Igor Bondarevsky vs David Bronstein

In this structure, White's plan is to advance the pawn to c4. Depending on the situation, he may exchange on d5 and, after some exchanges, saddle Black with an isolated d-pawn. Alternatively, he can continue to push the pawn to c5 followed by a general pawn advance on the queenside as occurs in the game.
