## Chess Opening: Nimzo-Indian Defense Theory to Practice

Like we did in Chess Opening: Queen’s Gambit Theory to Practice to expound with examples on how QGD opening theory in Chess Opening: Control of Center – Part 3 can turn out in practice, here we show practical examples on Nimzo-Indian Defense theory discussed in Chess Opening: Control of Center – Part 2.

To show both sides of the defense, we picked up two games, one going in favor of White and the other in favor of Black. What should be interesting is that in both these games of approximately equal length, Garry Kasparov was on the Black side and both were played around the same period. It gives a better opportunity to understand what Kasparov (or his opponents) did right or wrong to produce different results! Both games use the chess opening of Nimzo-Indian Defense Normal Variation (ECO code: E53).
