World Chess Championship 1972
The World Chess Championship 1972 was a match between challenger Bobby Fischer of the United States and defending champion Boris Spassky of the Soviet Union for the World Chess Championship. The match took place in the Laugardalshöll arena in Reykjavík, Iceland and has been dubbed the Match of the Century. Fischer became the first American to be the official World Champion since Wilhelm Steinitz (the first world champion) became a naturalized American citizen in 1888. Fischer's win also ended 24 years of Soviet domination of the World Championship.
The first game started on July 11, 1972. The last game began on August 31 and was adjourned after 40 moves. Spassky resigned the next day without resuming play. Fischer won the match 12½–8½, becoming the eleventh official World Champion.
The match was played during the Cold War, but during a period of increasing détente. The Soviet chess system had long held a monopoly on the game at the highest level. Spassky was the latest in an uninterrupted chain of Soviet world chess champions, stretching back to the 1948 championship.
Fischer, the eccentric 29-year-old American, was a vocal critic of the Soviet chess domination, because he believed that Soviet players gained an unfair advantage by agreeing to short draws among themselves in tournaments. In August 1962 Sports Illustrated, and then in October the German magazine Der Spiegel, published a famous article by Fischer "The Russians Have Fixed World Chess" in which he expounded this view. Fischer himself rarely agreed to early draws in unclear positions.
The expectations on Spassky were enormous because for the Soviets, chess was part of the political system. While Fischer was often famously critical of his home country ("Americans want to plunk in front of a TV and don't want to open a book ..."), he too carried the burden of expectation because of the political significance of the match. No American had achieved the world championship since the first champion, Wilhelm Steinitz, became a naturalized American citizen in 1888. The excitement surrounding the match was such that it was called the "Match of the Century", even though the same term had been applied to the USSR vs. Rest of the World match just two years before.
Spassky, the champion, had lost the world championship match against Tigran Petrosian in 1966. In 1968, he won matches against Efim Geller, Bent Larsen, and Viktor Korchnoi to again win the right to challenge Petrosian for the title. This time Spassky triumphed, winning 12½–10½. He is often said to have (had) a "universal style", "involving an ability to play the most varied types of positions". However, Garry Kasparov notes that "from childhood he clearly had a leaning toward sharp, attacking play, and possessed a splendid feel for the initiative." Before the match, Fischer had played five games against Spassky, with two draws and Spassky winning three.
However, in the Candidates matches en route to becoming the challenger, Fischer had demolished world-class grandmasters Mark Taimanov and Bent Larsen, each by a perfect score of 6–0, a feat no one else had ever accomplished in any Candidates match. After that, Fischer had split the first five games of his match against former World Champion Tigran Petrosian, then closed out the match by winning the last four games. "No bare statement conveys the magnitude and impact of these results. ... Fischer sowed devastation." From the last seven rounds of the Interzonal until the first game against Petrosian, Fischer won 20 consecutive games, nearly all of which were against top grandmasters.
Fischer also had a much higher Elo rating than Spassky, or indeed any player in history. On the July 1972 FIDE rating list, Fischer's 2785 was a record 125 points ahead of the number two player – Spassky, whose rating was 2660. Fischer's recent results and record Elo rating made him the pre-match favorite. Other observers, however, noted that Fischer had never won a game against Spassky.
Spassky's seconds for the match were Efim Geller, Nikolai Krogius and Iivo Nei. Fischer's second was William Lombardy. His entourage also included lawyer Paul Marshall, who would play a significant role in the events surrounding the match, and USCF representative Fred Cramer. The match referee was Lothar Schmid.
For some time, it was doubtful that the match would be played at all. Shortly before the match, Fischer demanded that the players receive, in addition to the agreed-upon prize fund of $125,000 (5/8 to the winner, 3/8 to the loser) and 30% of the proceeds from television and film rights, 30% of the box-office receipts. He failed to arrive in Iceland for the opening ceremony on July 1. Fischer's behavior was seemingly full of contradictions, as it had been throughout his career. He finally flew to Iceland and agreed to play after a two-day postponement of the match by FIDE President Max Euwe, a surprise doubling of the prize fund by British investment banker Jim Slater, and much persuasion, including a phone call by Henry Kissinger to Fischer. Many commentators, particularly from the USSR, have suggested that all this (and his continuing demands and unreasonableness) was part of Fischer's plan to "psych out" Spassky. Fischer's supporters say that winning the World Championship was the mission of his life, that he simply wanted the setting to be perfect for it when he took the stage, and that his behavior was the same as it had always been.
World-class match play (i.e., a series of games between the same two opponents) often involves one or both players preparing one or two openings very deeply, and playing them repeatedly during the match. Preparation for such a match also involves analysis of those opening lines known to be played by the opponent. Fischer had been famous for his unusually narrow opening repertoire: for example, almost invariably playing 1.e4 as White, and almost always playing the Najdorf Variation of the Sicilian Defence as Black against 1.e4. He surprised Spassky by repeatedly switching openings, and by playing openings that he had never, or only rarely, played before (such as 1.c4 as White, and Alekhine's Defence, the Pirc Defence, and the Paulsen Sicilian as Black). Even in openings that Fischer had played before in the match, he continually deviated from the variations he had previously played, almost never repeating the same line twice in the match.

Portisch and Smyslov contested a six game playoff in Portoroz, Yugoslavia in early 1971 for the reserve position for the Candidates Tournament. The match ended 3–3; Portisch was declared the winner because of a better tie-break score in the main tournament.

1972 Championship match 
|This section uses algebraic notation to describe chess moves.|
The match was played as the best of 24 games, with wins counting 1 point and draws counting ½ point, and would end when one of the players scored 12½ points. If the match ended in a 12–12 tie, the defending champion (Spassky) would retain the title. The first time control was 40 moves in 2½ hours. Three games per week were scheduled. Each player was entitled to three postponements for medical reasons during the match. Games were scheduled to start on Sunday, Tuesday, and Thursday. If a game was adjourned, it was to be continued the next day. Saturday was a rest day.
Fischer insisted that a Staunton chess set from Jaques of London be used. The chessboard had to be remade at Fischer's request. The match was covered throughout the world. Fischer became a worldwide celebrity, described as the Einstein or Hitler of chess. His hotel received dozens of calls each day from women attracted to him, and Fischer enjoyed reading the numerous letters and telegrams that arrived with compliments or criticisms. Excitement grew as the match was postponed and people questioned whether Fischer would appear. Previously, he had come to the airport and, surrounded by reporters, left. The combination of "Will he play?" and American-versus-Russian created excitement throughout the world.

Fischer's disastrous start 
Game 1: Spassky 1 Fischer 0 (Nimzo–Indian) 
After a series of piece exchanges in a placid Nimzo–Indian Defence, the position in the diagram was reached after 29.b5. It appeared to be a dead-drawn ending, and no one would have been remotely surprised if the players had agreed to a draw here.
Remarkably, Fischer blundered with 29...Bxh2?, a move that few players above master level would have played in light of the obvious 30.g3 and the fact that the h-pawn cannot save the bishop, trapping the bishop. In exchange for the lost bishop, Black is only able to obtain two pawns (see chess piece relative value). According to Garry Kasparov, Fischer probably planned 30...h5 31.Ke2 h4 32.Kf3 h3 33.Kg4 Bg1, but overlooked that 34.Kxh3 Bxf2 keeps the bishop trapped. Svetozar Gligorić reports that Fischer made the move very quickly and thinks that he simply overlooked the intermediate move 35.Bd2, which prevents the black bishop from escaping via the e1-square. Anatoly Karpov suggested that Spassky was afraid of Fischer and wanted to show that he could draw with the white pieces, while Fischer wanted to disprove that as the game headed for a stale draw. Owing to unusual features in the position, Fischer had good drawing chances despite having only two pawns for the bishop. However, the position became hopeless after he made at least one more bad move before the adjournment, which took place after move 40. Fischer could still have drawn the game with the correct 39th or 40th move. He resigned on move 56.

Game 2: Fischer forfeits 
Following his loss Fischer made further demands on the organizers, including that all cameras be removed. When they were not, he refused to appear for Game 2, giving a default win to Spassky. His appeal was rejected. Karpov speculates that this forfeited game was actually a masterstroke on Fischer's part, a move designed specifically to upset Spassky's equanimity.
With the score now 2–0 in favor of Spassky, many observers believed that the match was over and Fischer would leave Iceland. He did not, a decision that some attribute to another phone call from Kissinger and a deluge of cablegrams to Fischer. Spassky, owing to his sporting spirit and respect and sympathy for Fischer, agreed to play the third game in a small room backstage, out of sight of the spectators. According to Pal Benko and Burt Hochberg, this concession was a psychological mistake by Spassky.
The turning point 
Game 3: Spassky 0 Fischer 1 (Modern Benoni) 
This game proved to be the turning point of the match. Lombardy wrote of the beginning of the game:
When Bobby arrived, Boris was, as usual, seated at the table. Bobby did not sit down but went around inspecting the television equipment, and at this point Boris betrayed indignant agitation. Bobby tested the remote-control camera for possible sources of noise. Schmid watched the proceedings and became anxious. He felt the match once more was in jeopardy. Schmid took Bobby by the arm in an effort to get him to the playing table. Bobby brushed off Schmid's entreaties. "The American grandmaster permitted himself great liberty in his remarks, which were very disagreeable to hear," Spassky said later. Finally satisfied with the camera, Bobby settled down for the match.
After 11.Qc2 (see diagram), Fischer demonstrated his acute intuitive feel for the position with 11...Nh5!? Allowing White to shatter Black's kingside pawn structure looks antipositional, but Fischer's assessment that his kingside attack created significant counterplay proved correct.
Surprised by Fischer's novelty, which he had gleaned from the Yugoslav grandmaster Dragoljub Velimirović, Spassky did not react in the best way. In particular, his 18th move, weakening the light squares, was a mistake.

Game 4: Fischer ½ Spassky ½ (Sicilian Sozin) 
Fischer as White played the Sozin Variation against Spassky's Sicilian Defence. Spassky played a pawn sacrifice, gaining a strong attack, but failed to convert it into a win, the game ending in a draw.

Game 5: Spassky 0 Fischer 1 (Nimzo–Indian) 
Another Nimzo–Indian, this time the Hübner Variation: 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Nf3 c5 5.e3 Nc6 6.Bd3 Bxc3+ 7.bxc3 d6. Fischer rebuffed Spassky's attempt to attack and obtained a blocked position where Spassky was saddled with weak pawns and his bishop pair had no prospects. After 26 moves, Spassky faced the position in the diagram, in which he blundered with 27.Qc2??, and resigned after Fischer's 27...Bxa4! After 28.Qxa4 Qxe4, Black's dual threats of 29...Qxg2# and 29...Qxe1# would decide; alternatively, 28.Qd2 (or 28.Qb1) Bxd1 29.Qxd1 Qxe4 30.Qd2 a4 wins.
Thus Fischer had drawn level (the score was now 2½ to 2½) in the match, although FIDE rules stipulated that the champion retained the title if the match ended in a tie (after 24 games).

The juggernaut continues 
Game 6: Fischer 1 Spassky 0 (QGD Tartakower) 
Fischer, who almost always opened with 1.e4, played 1.c4 for only the third time in a serious game. The game transposed to the Queen's Gambit Declined, Tartakower Variation. After 14.Bb5!? (introduced in Furman vs. Geller, Moscow 1970), Spassky responded with 14...a6?! (Geller had previously shown Spassky 14...Qb7!, the move with which he later beat Jan Timman at Hilversum 1973, but Spassky apparently forgot about it.) After 26.f5, White had a crushing attack.

After this game, Spassky joined the audience in applauding Fischer's win. This astounded Fischer, who called his opponent "a true sportsman". Spassky later called it the best game of the match. This win gave Fischer the lead for the first time in the match.
Game 7: Spassky ½ Fischer ½ (Sicilian Najdorf) 
Spassky played 1.e4 for the first time in the match. Fischer defended aggressively with his favorite Poisoned Pawn Variation of the Najdorf Sicilian. He consolidated his extra pawn and reached a winning endgame, but then played carelessly, allowing Spassky to salvage a draw. In the final position, Fischer had two extra pawns but had to execute a draw by perpetual check in order to escape being checkmated by Spassky's two rooks and knight.

Game 8: Fischer 1 Spassky 0 (English Opening) 
Fischer again played 1.c4; the game remained an English Opening rather than transposing to another opening as in game 6. Spassky gave up an exchange for little compensation in the way of a positional advantage, and it is unclear whether it was a sacrifice or a blunder. Fischer won, putting him ahead 5–3.

Game 9: Spassky ½ Fischer ½ (QGD Semi-Tarrasch) 
The game was delayed when Spassky took time off (pleading illness). The opening was a Semi-Tarrasch Variation of the Queen's Gambit Declined. Fischer played a theoretical novelty on the ninth move, and the game ended in a quiet draw after just 29 moves. The players' behavior, however, provided for much entertainment, with Fischer rocking back and forth in his chair and Spassky imitating him, which one spectator described as "two dead men dancing".

Game 10: Fischer 1 Spassky 0 (Ruy Lopez Breyer) 
Fischer played the Ruy Lopez, an opening on which he was a great expert. He initiated a dangerous attack on Spassky's king with 26.Bb3!, suddenly placing Black in a critical situation. Spassky sacrificed the exchange for a pawn, reaching a sharp endgame where his two connected passed pawns gave almost sufficient compensation for Fischer's small material advantage. Spassky had drawing chances, but played inexactly, and Fischer won the game with precise play.

Game 11: Spassky 1 Fischer 0 (Sicilian Najdorf) 
This game was a dramatic win for Spassky, his first since Games 1 and 2. As in Game 7, Fischer essayed his favorite Poisoned Pawn Variation; Spassky surprised him with the startling 14.Nb1 (given !! by many annotators at the time), retreating the knight to its starting position. Although later analysis showed that the move was only sufficient for equality if Black responded correctly, Fischer did not. After inferior defense by Fischer, Spassky trapped Fischer's queen and handed him his only defeat ever as Black in the Poisoned Pawn.

Game 13: Spassky 0 Fischer 1 (Alekhine's Defence) 
Fischer avoided the Sicilian Defence, with which he had lost Game 11, instead preferring Alekhine's Defence. The game swung one way, then another, and was finally adjourned at move 42 with Fischer having an edge in a sharp position but no clear win. The Soviet team's analysis convinced them that the position was drawn. Fischer stayed up until 8 a.m. the following morning analyzing it (the resumption being at 2:30 p.m.). He had not found a win either. Amazingly, he managed to set traps for Spassky, who fell into them and lost. Spassky's seconds were stunned, and Spassky himself refused to leave the board for a long time after the game was over, unable to believe the result. He remarked, "It is very strange. How can one lose with the opponent's only rook locked in completely at g8?"
Former World Champion Mikhail Botvinnik said that this game made a particularly strong impression on him. He called it "the highest creative achievement of Fischer". He resolved a drawish opposite-colored bishops endgame by sacrificing his bishop and trapping his own rook. "Then five passed pawns struggled with the white rook. Nothing similar had been seen before in chess".
David Bronstein said "Of all the games from the match, the 13th appeals to me most of all. When I play through the game I still cannot grasp the innermost motive behind this or that plan or even individual move. Like an enigma, it still teases my imagination."

When Spassky and Fischer shook hands, many in the audience thought that they had agreed to a draw, thinking that 75.Rf4 draws. But 75...Rxd4! 76.Rxd4 Ke2 wins; 75.Be5 Rd1 76.Kxb3 Re1 also wins for Black.
The next seven games (Games 14 through 20) were drawn. Fischer was unable to get the initiative. Spassky was choosing lines that Fischer was unable to break. With a three-point lead, Fischer was content to inch towards the title, and Spassky seemed resigned to his fate. The off-the-board antics continued, including a lawsuit against Fischer for damages by Chester Fox, who had filming rights to the match (Fischer had objected to what he said were noticeable camera noises, and the Icelandic hosts had reluctantly – they were to share in film revenues along with the two contestants – removed the television cameras), a Fischer demand to remove the first seven rows of spectators (eventually, three rows were cleared), and Soviet claims that Fischer was using electronic and chemical devices to 'control' Spassky, resulting in an Icelandic police sweep of the hall.
Game 14: Fischer ½ Spassky ½ (QGD Harrwitz) 
The game was postponed at Spassky's request. Fischer was again White in a Queen's Gambit Declined. He played carelessly and lost a pawn on move 21. However, Spassky blundered it back on move 27 and the game settled into a 40-move draw.

Game 15: Spassky ½ Fischer ½ (Sicilian Najdorf) 
Fischer returned to the Najdorf Sicilian, but played the main line rather than the Poisoned Pawn Variation with which he had lost Game 11. At move 13, Fischer sacrificed a pawn for counterplay. Spassky accepted it, and later a second pawn, but allowed Fischer a very strong attack. Spassky, on the brink of disaster, "found miraculous replies while in time pressure" and Fischer was only able to achieve a draw by threefold repetition after 43 moves. Two years later, Yugoslav grandmaster Dragoljub Velimirović improved on Spassky's play with the piece sacrifice 14.Bxb5!?, winning a crushing victory in Velimirović vs. Al Kazzaz, Nice Olympiad 1974. Black in turn later improved on Fischer's 12...0-0-0 with 12...b4.

Game 16: Fischer ½ Spassky ½ (Ruy Lopez Exchange) 
Fischer played the Exchange Variation of the Ruy Lopez, a favorite line of his. Spassky defended well, and after a tactical flurry in the endgame, ended up with the nominal advantage of an extra pawn in a rook ending known to be an easy book draw. Although a draw could have been agreed after move 34, Spassky "used his symbolic material advantage for a little psychological torture", prolonging the game until move 60 before agreeing to a draw.

Game 21: Spassky 0 Fischer 1 (Sicilian Paulsen) 
This game turned out to be the last game. Fischer used a line of the Sicilian that he had never before played as Black, and further surprised Spassky with a novelty on move eight. Spassky played badly in the endgame and the game was adjourned with a big advantage for Fischer. However, Fischer's 40th move was not the best; he should have played 40...Kg4! before ...h5 (his actual 40th move). Had Spassky sealed 41.Kh3! (preventing ...Kg4), he would have had drawing chances. However, his 41.Bd7? would have allowed Black to win with 41...Kg4 followed by pushing his h-pawn. On September 1, the day scheduled for resumption of the game, arbiter Lothar Schmid informed Fischer and the audience that Spassky had resigned the game by telephone, making Fischer the winner of the match.

The final score was 12½–8½ in favor of Fischer, making him the eleventh World Champion. Spassky won three games (including the forfeit in game 2), Fischer won seven games, and there were eleven draws. The controversial Grandmaster Jan Donner criticized Spassky's telephone resignation in print, although Fischer had outright forfeited a game earlier in the match.

- Gligorić 1972 (p. 34), Alexander 1972 (p. 86), and Evans & Smith 1973 (p. 29) all give Fischer's 40th move as a bad move, stating that he could still have drawn with the correct 40th move. More recent books by Kasparov 2004 (p. 435) and Plisetsky & Voronkov (p. 443) give Fischer's 39th move as weak, claiming that his last opportunity to draw the game was with 39...e5! Mednis 1997 (pp. 274–76) says that Fischer's 37th move was bad, and thinks he missed a draw with 37...a6. Euwe and Timman (pp. 55–57), citing analysis of Friðrik Ólafsson and independently Jon Speelman say that Fischer could have forced a draw after 36.a4? with 37...a6 or with 39...e5.
Speelman analyzed the position in depth in his 1980 book, Analysing the Endgame, pp. 74–80, taking into account previous analysis by others. He states that 29...Bxh2 was a bad move, giving White excellent winning chances without any compensating chances for Black. However, the position was not lost after that move; but after two more errors (37...Ke4?! and 39...f5?), Black was clearly lost.
