Najdorf Powerbook 2012

New opening ideas these days are always discovered with the help of our silicon friends. Equally, it’s not rare for the theory that will define tomorrow’s games to be forged in the computer-computer battles in the Engine room on Playchess.com. The new Najdorf powerbook brings these two powerful elements together and presents you with both the current theoretical standing based on 16,000 master level tournament games and more than 700,000 high quality engine battles from Playchess.com to make a gigantic and up to the minute position tree. This novel approach offers you THE complete and definitive evaluation of every Najdorf variation.
