The idea is as clever and original as its inventor. With 3.f3 (after l.d4 f6 2.c4 g6), Alexander Alekhine designed a promising strategy to take Grunfeld players out of their comfort zone. Alekhine's find was a great idea in the days of the fourth World Champion and it still is. In fact, its recent revival has opened up a new chapter in chess opening theory. Top players like Vishy Anand and Levon Aronian have used it with success. The popularity of this variation is easy to understand: it offers White much better chances for an advantage than the normal 3.c3 because it makes 3... d5, the favorite reply of Grünfeld players, less attractive. Sabotage the Grünfeld offers a highly practical repertoire based on 3.f3, covering all of Black's answers. Larry Kaufman, who has first-hand experience with the variation, has analyzed the lines deeply with the high-end computer programs Komodo and Houdini 3. The ensuing positions are diverse and fresh. White avoids mainstream theory and has a good chance to demolish Black's position. Kaufman offers a perfect weapon for 1.d4 players who want to steer their game into the direction they want.
