Challenging the Nimzo-Indianby David Vigorito325pp. (2007 Quality Chess)Every competitive chess player needs a sound grasp of how to play this opening -- and especially how to meet the most popular lines. The Nimzo-Indian is Black’s most respected answer to 1.d4 and is immensely popular at all levels, from club championship to world championship. In fact, the reputation of the Nimzo is so high that some players prefer simply to avoid it and give up all hopes of an opening advantage. American International master David Vigorito shows that this negative approach is unnecessary.Challenging the Nimzo-Indian provides White with a complete repertoire based on 4.Qc2. There is sufficient detail for the reader to build a dangerous repertoire with wither color. The chess is certainly at a high level, but Vigorito’s logical approach and clear conclusions means that readers can easily grasp the concepts, while less-experienced players can play through the high-quality example games that are comprehensively explained.
