Bobby Fischer's Opening Theory and Endgame
BOBBY FISCHER'S OPENING THEORY AND ENDGAME
OPENING THEORY
Fischer's opening repertoire was narrow in some ways. As White, Fischer almost exclusively played 1.e4 throughout his career. He played 1.d4 with White only once in a serious game, during a blitz tournament. In spite of this narrowness, he was considered by some of his rivals to be unpredictable in his opening play, and a difficult opponent to prepare for.
As Black, Fischer would usually play the Najdorf Sicilian against 1.e4, and the King's Indian Defense against 1.d4, only rarely venturing into the Nimzo-Indian (1.d4 Nf6 2.c4 e6 3.Nc3 Bb4), Benoni, Grünfeld or Neo-Grünfeld. Fischer acknowledged difficulty playing against the Winawer Variation of the French Defense (1.e4 e6 2.d4 d5 3.Nc3 Bb4), but maintained that the Winawer was unsound because it exposed Black's kingside, and that, in his view, "Black was trading off his good bishop with 3...Bb4 and ...Bxc3." Later on Fischer said: "I may yet be forced to admit that the Winawer is sound. But I doubt it! The defense is anti-positional and weakens the K-side."
Fischer was renowned for his opening preparation and made numerous contributions to chess opening theory. He was one of the foremost experts on the Ruy Lopez. A line of the Exchange Variation (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0) is sometimes called the "Fischer Variation" after he successfully resurrected it at the 1966 Havana Olympiad. Fischer's lifetime score with the move 5.0-0 in tournament and match games was eight wins, three draws, and no losses (86.36%).
Fischer was a recognized expert in the black side of the Najdorf Sicilian and the King's Indian Defense. He used the Grünfeld Defense and Neo-Grünfeld Defense to win his celebrated games against Donald and Robert Byrne, and played a theoretical novelty in the Grünfeld against reigning world champion Mikhail Botvinnik, refuting Botvinnik's prepared analysis over the board. In the Nimzo-Indian Defense, the line beginning with 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 b6 5.Ne2 Ba6 was named after him.
Fischer established the viability of the so-called Poisoned Pawn Variation of the Najdorf Sicilian (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Qb6). This bold queen sortie, to snatch a pawn at the expense of development, had been considered dubious, but Fischer succeeded in proving its soundness. Out of ten tournament and match games as Black in the Poisoned Pawn, Fischer scored 70%, winning five, drawing four, and losing only one: the 11th game of his 1972 match against Spassky. Following Fischer's use, the Poisoned Pawn Variation became a respected line, utilized by many of the world's leading players. Fischer's 10.f5 in this line against Efim Geller quickly became the main line of the Poisoned Pawn.
On the white side of the Sicilian, Fischer made advances to the theory of the line beginning 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 (or e6) 6.Bc4, which has sometimes been named after him.
In 1961, prompted by a loss the year before to Spassky, Fischer wrote an article titled "A Bust to the King's Gambit" for the first issue of the American Chess Quarterly, in which he stated, "In my opinion, the King's Gambit is busted. It loses by force." Fischer recommended 1.e4 e5 2.f4 exf4 3.Nf3 d6, which has since become known as the Fischer Defense, as a refutation to the King's Gambit. Fischer later played the King's Gambit as White in three tournament games, winning them all.
ENDGAME
Fischer had excellent endgame technique. International Master Jeremy Silman listed him as one of the five best endgame players (along with Emanuel Lasker, Akiba Rubinstein, José Raúl Capablanca and Vasily Smyslov), calling Fischer a "master of bishop endings". The endgame of a rook, bishop, and pawns against a rook, knight, and pawns has sometimes been called the "Fischer Endgame" because of several instructive wins by Fischer (with the bishop), including three against Mark Taimanov in 1970 and 1971.
