HOW TO PLAY THE NIMZO-INDIAN?
The opening arising after the moves 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 carries the name of Aaron Nimzowitsch (1886-1935), who played some wonderful games with it and contributed many important ideas. However, the Nimzo-Indian can well be called the opening of the world champions. Capablanca employed it and lost one of the most legendary games in chess history - against Botwinnik, another world champion. His successors adopted the Nimzo-Indian as well, often even with both colours. Robert Fischer scored his greatest achievements with this opening in 1972 when he -among other things thanks to a brilliant Nimzo-Indian victory - became world champion. Also his heir to the throne, Karpov, used it to good success, and after him Kasparov. Having less the character of a theoretical work, Reinhold Rippberger 's CD follows a similar approach like "King 's Indian with f4 " - not concentrating on concrete variations, but rather showing how to play certain types of positions. Apart from the 21 introductory texts, the heart of the CD are the 300 games with many text commentaries. Furthermore, the author presents a database with 35 games featuring training questions. On top of that, the CD contains two additional databases with more than 47,000 games.
