Denver, 1971. On his march to the world title, Bobby Fischer did the impossible: he won his Candidates matches against Mark Taimanov and then Bent Larsen by the unthinkable score of 6–0 each. This is Game 3 against Larsen, a textbook Sicilian Sozin Attack in which Fischer ripped open the f-file with 11.f5! and overran Larsen's position. The streak of perfection that preceded his title match is unmatched in chess history.
In open Sicilians, the f-pawn break and pressure on f7 and the e6/d6 pawns are White's bread and butter. Fischer shows the model plan: aim the bishop at f7, open the f-file with f4–f5, and convert the resulting weaknesses into a winning attack and a clean endgame.
Fischer won the six-game Candidates semifinal 6–0 — a perfect sweep against one of the strongest players in the world. Combined with his 6–0 win over Taimanov, it is the most dominant run in the history of elite chess.
It is the classic Sicilian Sozin breakthrough: White opens the f-file and attacks the e6 pawn, turning the pressure already aimed at f7 into a concrete assault on Black's king.
Yes — take the board as White at move 11 and try to find the f5 break and the attack, or replay the whole game move by move, no sign-up.
