“The two played the most uncompromising of openings, the Poison Pawn Variation in the Siciian Najdorf. One might think that, after all theee years, everything is understood about this ferociously complex tactical variation. With the growth of computer chess that is far from true. Using computers has changed people’s conception of what positions are defensible. Thus players are stronger. That is one reason so many people are rated over 2700, not inflation in the numbers”.
