The Danish Gambit opening allows for rapid attack development for white. This video explores the book line moves, along with possible counter-play by black.
This DVD is for players who are absolutely serious about playing the Najdorf Sicilian; casual players need not apply. The DVD box for How to Play the Najdorf Vol.1 says that it contains two and a half hours of “first class private tuition”; the disk does indeed contain high-level instruction suitable for stronger club players and titled players alike. The instruction is subdivided into eight sections: an introduction, early deviations, two sections on White’s 6.Bg5, one on the Gothenburg Variation, and four sections on the Poisoned Pawn Variation. While Kasparov’s tutorials do concentrate on the ideas within each variation, there is also some memorization required and it would be helpful for the viewer to have some prior Najdorf experience. For advanced players, Kasparov’s How to Play the Najdorf Vol.1 will be a goldmine of ideas and an excellent glimpse into the analytical mind of a chess champion.
