Korchnoi and Spassky. It is difficult to believe that black can prove full
compensation for the bishop pair, although the decision to delay ...Bb7 is
based on the idea to play, in many cases to exchange light-squared bishops on
a6. Moreover, in comparison with other variations based on a combination of ...

compensation in the game continuation, and reasonable compensation in the
analagous positions with 8...Bxc4, although that move may be rather sounder
