By choosing variations that lead to similar structures, highly experienced player, writer and teacher Sam Collins has put together an ideal repertoire for players with limited study time. White opens with 1 e4 and develops his pieces to natural squares and seeks open lines and the initiative. A successful repertoire is more than a set of variations; it also requires strategic understanding of the resulting positions and a knowledge of the key tactical methods and patterns. Because many of Collins’s recommendations lead to familiar structures, ideas can easily be transplanted from one opening to another. He gives complete illustrative games that emphasize the main themes. The specific analysis is up-to-the-minute and features many new ideas that have proven their worth in recent grandmaster practice. Throughout there is a great deal of attention to move-order subtleties and on finding nuances in ‘sidelines’ that your opponents are most unlikely to have examined in detail. Irish international master Sam Collins won the championship of his home country in 2002 and 2014. He has represented Ireland in numerous olympiads, winning an individual gold medal at Bled in 2002. He is also an experienced chess teacher who has lectured at the Berkeley Chess School in California. His previous books for Gambit were Chess Explained: The c3 Sicilian and the highly successful general opening work Understanding the Chess Openings.
