[. . . ] It is no longer typical to see top-level players playing only In fact, Korchnoi at the time of this game was one of the best in the world, and his forte was defense. Many fine players would attack him ingeniously, only to break up on his rock-like fortifications. Still, World Champion Karpov crushes him in only 27 moves with a mating attack!In a classic manner against Black's Sicilian Dragon defense (so named probably because of the "tail" of control Black's bishop makes from g7 to a1), Karpov plays the St. Tigran Petrosian, Moscow, 1969 Spassky won the world championship from Petrosian in the match that produced this game. In this English Opening that becomes a Queen's Gambit, you'll see that once again White gets a strong center and quick development of his pieces. Rd1, you can sense that Black is in danger. His king has no piece defenders; his forces seem passive while White's are aggressively coordinated. As often happens in such situations, White breaks through with a pawn push in the center, in this case 15. It clears the board for White's more active forces. Edly to trade queens, but White wisely rebuffs these offers, which would take much of the power off the board. white's d-pawn becomes a star , advancing all the way to the 7th rank. Because of this queening threat, White is able to sacrifice his queen for one of Black's defending rooks. In the final position, it's hopeless for Black because White will either promote his pawn to a queen or capture whatever Black uses to block on d8. Reuben Fine, New York, 1963 Nine years before winning the world championship, Bobby Fischer played this Evan's Gambit (a variation of the Giuoco Piano) against his famous elder. Bobby sacrifices two pawns in order to get his pieces out quickly. , sacrificing another pawn to force the Black queen away from the g7-square. After that, Black's king will be stuck in the center and in danger of the h4d8 diagonal. , forces Fine to resign, because he must move his queen from the critical black diagonal h4d8. Qxg3, White ignores the capture of his own queen and plays 18. Johannessen, Havana, 1966 During the first half of this game, a Queen's Gambit Slav, the great Hungarian grandmaster Lajos Portisch locks up the center with a d4-e5 structure by move 14. This gives him a "beachhead" on e5 and makes it hard for Black to counterattack in the center, which is the standard antidote for an attack on the wing.
