Former World Champion Anatoly Karpov demonstrated the power and the flexibility of the system by scoring some great victories with it in the 1970s.Karpov had the ins and outs from the horse's mouth as its inventor, Igor Zaitsev himself, was his long-time second. Zaitsev had discovered that in the Ruy Lopez often the best way for Black to fight for an advantage was to play an early...Bb7 and...Re8 in order to put pressure on White's centre, more specifically the pawn on e4.
