The O'Kelly variation of the Sicilian Defense (1 e4 c5 2 Nf3 a6) is a wonderful system for those who enjoy playing Sicilian positions but don't want to get bogged down in heavy theory. The O'Kelly relies far more on an understanding of general strategic ideas and middlegame planning than on rote memorization of opening moves. One of the benefits of the O'Kelly is that White's natural continuation of 3 d4, although very frequently played, permits Black comfortable development and an easy game.

In Play the O'Kelly Sicilian, highly experienced chess author and coach Andrew Martin guides the reader through the complexities of the O'Kelly and carves out a repertoire for Black. He examines all aspects of this fascinating opening and provides the reader with well-researched, fresh, and innovative analysis. Each annotated game has valuable lessons on how to play the opening and contains instructive commentary on typical middlegame plans.
