Fischer - Spassky 1972 WCH Game 10 (C95)
In this game Fischer allows Spassky to play a favorite (Breyer) defense to the Ruy Lopez but varies from his usual method of play on move 11, possibly surprising his opponent. Soon out of the opening Fischer snatches a pawn giving Spassky dangerous counterplay, which Fischer avoids by making his own pawn offering a few moves later. A complicated middlegame ends up in an endgame favorable to Bobby after Boris once again misses several potential opportunities to avoid defeat.
"In the Breyer Variation 9.h3 Nb8 (of the RL) Black redevelops the QN to d7, centralizing his pieces and maintaining control of the center. This allows White to choose a plan of play on the kingside, queenside or both. The Breyer is still sound, but has been employed less in recent years as White has freedom to choose his/her plan" - MCO-15 (2008) p. 80
