For the new edition of the Najdorf Powerbook 2020 we used exclusively games from the engine room of playchess.com. Nevertheless the number of games on which the book is based has risen to an incredible 3.69 million. That enables reliable statistical analyses not only for all the main lines but also for many side-lines. A must for all Najdorf players! The Najdorf Powerbook 2020 is an opening book which you can use with your Fritz or ChessBase program. It does not contain a database – so no games are included in the package.
System requirements: Pentium PC, 2 GB RAM, Windows 10, 8 or 7 and Fritz 13, 14, 15, 16 or ChessBase 15, 14, 13 or 12 and DVD drive.
Anyone who studies the Najdorf tree to search for the best variations in the English Attack has plenty to choose from. But many players with White will perhaps be on the lookout for promising side-lines, like the exotic 6.Bd3, which has been played, for example, by Sergey Karjakin in some blitz games. Of course there is the much more solid 6.Be2 e5 7.Nb3 Be7 and after 8.0-0 0-0 9.Qd3 intending 9...Be6 10.Bd2!? (taking aim at a5) there is also 8.Bf3 Be6 directed against …d5.
9.Be3 is an idea worth noting. The statistics based on more than 11 000 games are of course more reliable than the approx. over 100 games in the online database. And what if Black just doesn’t play 6...e5? After 6...e6 White can naturally continue in Scheveningen style, but what about this line: 7.Be3 Qc7 8.Qd2!? b5 9.a3 Bb7 10.f3
The results for White are impressive and in addition anyone who is a fan of sharp lines will get his money’s worth.
