Pre-tournament

Ever since 1993, when Garry Kasparov and Nigel Short broke away from chess governing body FIDE to play their world championship match under the auspices of the newly formed Professional Chess Association, there had been two chess world championships: one organised by FIDE (which used the knock-out format from 1998 to 2004) and one by a variety of other bodies (in the form of a long match between champion and challenger). The 2004 FIDE Championship was a part of what was, at the time, the most serious attempt yet to reunify the title, the so-called Prague Agreement.

The plan under this agreement when it was drawn up in 2002 was that reigning FIDE world champion Ruslan Ponomariov and world number one on the FIDE Elo rating list Garry Kasparov played a match, and that the so-called "classical" world champion Vladimir Kramnik and winner of the 2002 Dortmund tournament (which turned out to be Péter Lékó) played each other. The winners of these two matches would then play one another to produce a unified champion.

The match between Ponomariov and Kasparov, however, fell through after FIDE refused to alter various things in the contract on Ponomariov's request, and he refused to sign. FIDE announced that instead the winner of the next FIDE knock-out championship played against Kasparov in a match to be held not later than July 2005 (Kramnik and Lékó played their match in September–October 2004). Therefore, as well as the championship determining who was to be the next FIDE world champion, it would also determine who played Kasparov in what was effectively a semifinal match for the unified championship.

Post-tournament

After Kasimdzhanov's victory, FIDE opened the bidding for the Kasimdzhanov-Kasparov match in August 2004, bids to be received by September 15. This deadline was later extended to September 25. The organiser was to be chosen at the FIDE Presidential Board meeting in October 2004, but in fact, FIDE President Kirsan Ilyumzhinov announced ahead of this time that the match had been awarded to the United Arab Emirates.

The plan did not come to fruition: the promised funding for the match never arrived, and plans to hold the match instead in Turkey also came to nothing. The whole question of how and when the Kasparov-Kasimdzhanov match would take place, or what would occur in its stead, was made irrelevant by Kasparov's announcement in March 2005 that he was retiring from serious chess.

Kasimdzhanov's victory did, however, earn him (and runner-up Michael Adams) an invitation to the FIDE World Chess Championship 2005. Kasimdzhanov also gained automatic entry to the Candidates Tournament for the FIDE World Chess Championship 2007.

The world championship was eventually reunified in 2006, when classical champion Kramnik defeated the winner of the FIDE World Chess Championship 2005, Veselin Topalov.

Format

One source of criticism, in common with when it has been used for previous FIDE championships, has been the event's format. In particular, the relatively quick time controls have been controversial. (90 minutes for the first 40 moves, followed by 15 minutes until the end of the game and an incremental time of 30 seconds per move from move one.) Zhang Zhong, for example, was quoted as saying "the time limit is too fast for such a world championship. We should call it a World Cup … a world championship needs more classic time controls"^[1] and Nigel Short claimed that "If you took the top 100 players and survey their opinion you would probably find around 75% are against this time control".^[2]

Another criticism centered on the knockout format of the tournament. Although knockout matches had been used prior to the introduction of this tournament format, the brevity of these matches (Best of 2 elimination matches with a Best of 6 Championship Match, as opposed to the Best of 10 elimination matches and Best of 24 Championship Match seen in earlier cycles) led many to consider them to be of little value in determining the better player.

Location

Perhaps the greatest criticism concerned the choice of Libya as venue. Claims of human rights abuses, and state-sponsored terrorism caused some consternation, but on a more practical level the country's history of not allowing entry to citizens of Israel has been of some concern, as three Israeli players (Boris Gelfand, Emil Sutovsky and Ilya Smirin) had either qualified for the championships or were high on the list of reserves (in the event of qualifiers choosing not to play). Additionally, a number of players had joint Israeli and American citizenship, and so were also expected to be disallowed entry.

With this in mind, FIDE originally announced that a parallel event in Malta would be held alongside the one in Tripoli to ensure that Israeli players could take part—Sutovsky sent his entry form back on the condition he played in Malta.^[3] This parallel event was cancelled, however, following a press release from the Libyan authorities that "The Great Socialist People's Libyan Arab Jamahiriya will pleasantly provide entry visas to all the qualified participants of this great Championship", which was taken by most (including FIDE) to mean that all players, including Israelis, would be welcome to take part. This appeared to be contradicted by a statement from Mohammed Qadhafi, chairman of the Libyan Olympic Committee (FIDE is affiliated with the IOC) and son of Libyan leader Muammar al-Gaddafi, that "We [the Libyans] did not and will not invite the Zionist enemy to this championship."^[4]

Several prominent figures criticized FIDE over this matter, with both Grandmaster Boris Gulko, a Jew with joint American and Israeli citizenship, and Beatriz Marinello, president of the United States Chess Federation writing open letters to FIDE criticizing their handling of the issue.^[3]

On May 13, the Anti-Defamation League wrote to FIDE, saying it was "troubling" that Libya should be hosting the championships, and urging FIDE to ensure that Israeli players were treated equally. The letter raised concerns over the Libyans not allowing the coaches and families of Israeli players into the country.^[5] Similar concerns were expressed in an Association of Chess Professionals (ACP) open letter of May 26^[6] (the ACP also criticized several other aspects of the tournament's organization).

FIDE maintained throughout that Israeli players would have been issued with visas upon their arrival in Libya. This assurance was never put to the test, however: none of the qualified players took part in the championship and Boris Gulko, who has joint American and Israeli citizenship, withdrew from the event after initially indicating he would play (fellow Americans Alexander Shabalov and Alexander Onischuk also withdrew in sympathy with the concerns of Gulko and others^[7]). The only player in the final list of participants with an Israeli passport—Vadim Milov, representing Switzerland—never travelled to Libya: he complained that his official invitation to the event had arrived so late (on the day of the opening ceremony, one day before the first game) that it was physically impossible for him to get to Libya with it in time. Milov claims that this constituted a deliberate attempt by FIDE to exclude him.^[8] In response, FIDE said that the delay in sending Milov's invitation was due to Milov not sending them his passport details until a deadline had passed, and that even with this delay, Milov could still have arrived in Tripoli in time for his first game, which they had offered to postpone if necessary.^[9] Milov took his case to the Court of Arbitration for Sport (Tribunal Arbitral de Sport) in Lausanne^[10] which found that FIDE "undertook extraordinary efforts to make sure that Claimant [Milov] could participate in the WCC 2004 although such efforts could and should have been made earlier" and ultimately cleared FIDE of any ill-intentioned effort to exclude Milov, concluding "there is no ground for Claimant to claim damages from Respondent." Milov later responded to this decision in an open letter.^[11]

It was also reported that the Israeli chess federation was considering suing FIDE "for compensation for the damages incurred by our exclusion from this tournament".^[12]

Strength

As a result of these and other factors, many of the players who were invited to take part in the tournament – including world number two Viswanathan Anand, and number six Peter Svidler – declined. In addition, Kasparov, Kramnik and Lékó did not take part owing to them being involved at a later stage of the reunification process. This led to a somewhat weaker lineup than previous championships, with only three of the world's top ten accepting the invitation to play, and only two of those actually turning up to the event. This weakness has itself been a cause of controversy, with claims that any tournament with so many top players missing should not be considered a World Championship at all.

The position after move 120.

The games of round one were played on June 19 and June 20, with tie-breaks on the evening of June 20. Four of the sixty-four scheduled round one matches games did not take place at all: Morozevich, Milov, Shulman and Hjartarson all failed to appear for their first game; their opponents (Elarbi, Neelotpal, Tkachiev and Kudrin) progressed into round two by default. Top seed Topalov had problems with his flight into Libya, and the start of his first game had to be postponed until 5 pm. The seeding system in operation, whereby the top seed plays the bottom seed, the number 2 plays number 127, number 3 plays number 126 and so on, meant that serious round one upsets were unlikely, and indeed there were few surprises. Several of the top players, among them Ye (seeded 12), Azmaiparashvili (14) and Rublevsky (17) required the first pair of tie-break games to advance, and Vallejo Pons (21) only went through after the two five-minute games, but in the end, all progressed as expected. The biggest first-round upset in terms of rating difference was Kritz (rated 2534 and seeded 105) knocking out Sasikiran (2659 / 24) by winning both standard games. Apart from the defaults, he and Hamdouchi (who beat Motylev) were the only players to overcome a rating difference of more than 100 points to advance to round two.

Position before 21.Rc1.

The games of round two were played on June 21 and June 22, with tie-breaks on the evening of June 22. Round two saw one major upset and a number of smaller ones. The big surprise was Nigel Short (6) being knocked out by Michał Krasenkow (59). In game one, Short (with white) had the advantage of rook for knight and pawn and was trying to squeeze a win out of it when, after around five hours of play, the position in the diagram arose. Short played the blunder 121. Re6?? (see algebraic notation), and resigned a move later. He obtained a slight advantage in game two, but it wasn't enough to win, and the draw knocked him out of the competition. Other upsets included Sokolov (9) losing out to Kharlov (73), Malakhov (7) being knocked out by Domínguez (58) in the last tie-breaker and Azmaiparashvili (14) losing to Lastin (51). Most of the top players had little difficulty, however: Topalov (1), Adams (3), Grischuk (4), Nisipeanu (8), and Dreev (10) all progressed after the first two games. Ivanchuk (5) required tie-breakers, but still advanced to round three as expected.

The games of round three were played on June 23 and June 24, with tie-breaks on the evening of June 24. The surprise of round three was Ivanchuk (5) being knocked out by Kasimdzhanov (28). The two standard time control games had been fairly quiet affairs and were both drawn (the second, with Kasimdzhanov white, after just 16 moves) and the first rapid game was also drawn. In the second, Ivanchuk, despite having white, did little to press for a win, and the fairly level position shown arose. 21. Bxb7 Qxb7 appears to be equal, but Ivanchuk instead played 21. Rc1?, which simply lost a pawn to 21. ... Qxa3. Ivanchuk resigned six moves later, in a position which was certainly worse but from which many players would have at least tried to play on. Ivanchuk has something of a reputation for being let down by his nerves, and this may have been another instance of that. Elsewhere, there were minor surprises when Krasenkow (59) followed up on his victory over Short to eliminate Zvjaginsev (27), 16-year-old Nakamura (83) – the youngest player remaining in the tournament – dispatched Lastin (51), and Grischuk (4) required the blitz tie-breakers to see off Filippov (36). Kozul's (49) win over Rublevsky (17) took his score for the event to 5½/6, with a Performance rating of over 3000. Top seeds Topalov (1) and Adams (3) advanced with little difficulty, winning their games with white and drawing with black.

After a rest day on June 25, the games of round four were played on June 26 and June 27, with tie-breaks on the evening of June 27. Two surprise results occurred when Kharlov (73) and Domínguez continued their impressive runs by knocking out Nisipeanu (8) and Dreev (10), respectively, both recording their second win against a top 10 player in the tournament.

In game two, Adams played the Petrov Defence. His knight ended up somewhat out of the game on a5, and his e5 square was weak, allowing Kasimdzhanov to plant a knight there and obtain a significant positional advantage. Both players blundered on the last move of the time control (after which they each got an extra 15 minutes): in the position shown, Kasimdzhanov played 40.Kf2? which Adams should have answered with 40...Nxb5! which is at least equal; instead, he returned the favour with 40...Rc8?, and White was still significantly better. Following 41.Rb1 g5 42.b6 axb6 43.axb6 gxf4 44.gxf4 Bd5 45.Bd3, a similar thing happened when Adams blundered with 45...Rf8? This pins the f4 pawn to the king and so seems to leave the e5 knight undefended, and it was probably for this reason that Kasimdzhanov played 46.Ke3? However, he could have won immediately with 46.Rxc5! when 46...Rxe5 does not work because of 47.Rc7+ when Black must either break the pin with 47...Kf6 or 47...Rf7 48.Rxf7 Kxf7 thus allowing fxe5; or else be mated with 47...Kg8 48.Rg1+ Kh8 49.Rxh7# or 47...Kh8 48.Rxh7+ Kg8 49.Rg1+ Rg5 50.Rxg5#. 46...Ne6 is also no good after 47.Rxd5 Nxf4 48.Rd7 Rxd7 49.Nxd7 Nxd3+ 50.Ke3. In the event, Adams did not take advantage of White's mistake, and continued with 46...Nc6? (46...Ne6 was a much better try). The game ended 47.Rxc5 Nxe5 48.fxe5 Bb7 49.Be4 Rff7 50.Bxb7 Rxb7 51.Ke4 Rfd7 52.Rc6 Kf8 53.e6 Rd2 54.Rf1+ Ke8 55.Rc8+ and Adams resigned.

Game three was another Kan Sicilian, but Adams varied from game one early with 5.Nc3 instead of 5.Bd3. His 10.Qd2 in reply to 9...Bc5 was a new move (previously, 10.e5, which Adams had himself played in his win against Topalov at Tilburg in 1998, was normal): this may be planning 11.Qg5 which would prompt a weakening ...g6; if black defends with 10...f6, for example, then White can play 11.b4!? when 11...Bxb4 (11...Bd6 may be better) 12.Nxb5 leaves White with a strong position. Kasimdzhanov instead retreated with 10...Be7, losing a tempo, and he never managed to equalise. Adams' pieces ended up being much more active than their black counterparts, and he eventually planted a strong knight on b5 and a rook on the seventh rank. Adams won a pawn, but turning that into a win did not seem straightforward until Kasimdzhanov played 30...Rd6?! in the position shown. This allowed Adams to make simplifying exchanges with 31.Rxb4 axb4 32.Ne7+ Qxe7 33.Qxd6. Now exchanging queens leaves a fairly trivially won rook endgame, so Kasimdzhanov instead played 33...Qe2, but this lost another pawn after 34.Rd4 h5 35.Qxb4, and White had a won position. Kasimdzhanov resigned on move 47, making the match level at 1½–1½.

After losing with the Petrov in game two, Adams instead played his usual 2...Nc6. Kasimdzhanov played the exchange variation of the Ruy Lopez, as he had against Grischuk in round five, and they followed theory until Adams' novelty 12...f5. White exchanged pieces and played against Black's weakened queenside, a typical plan in this variation. Adams came under considerable pressure, but it seemed he may be able to hold White off until, in the diagrammed position, he apparently tired of passive defence, and lashed out with 30...Rxa5? (30...Ke7 is probably better), which after 31.bxa5 Rxa5 32.f4! Bxf4 33.Rg6 Kf7 34.Rxe6 Kxe6 35.Bxf4 left him with just two weak pawns for a bishop. Adams resigned on move 40.

A pawn down, Adams was happy to take the draw with 42...Bxf2+ 43.Kxf2 Qc2+, when White has no way to escape the perpetual check. In fact, though, Adams could have won with 42...Qe4! when there is no satisfactory way to escape the mate threat 43...Be5+ 44.f4 Qxf4+ 45.Kg2 Qg3+ 46.Kf1 Qf3+ 47.Kg1 Bd4+ 48.Kh2 Qf2+ 49.Kh1 Qg1#. If White gives his king a flight square on f2 with 43.f3, then he gets mated by 43...Qe1+ 44.Kg4 Qg1+ 45.Kf4 e5+ 46.Ke4 Qe3+ 47.Kd5 Qxf3#; 43.Qxh7+ also leaves White doomed after 43...Kf8: for example, 44.Qh6+ Bg7 45.Qh4 Be5+ 46.f4 Qe1+ 47.Kg4 Qe2+ 48.Kg3 Bc3, and white has no defence to ...Be1; or 44.Qd7 Be5+ 45.f4 Bxf4+ (more simply, something like 45...Qxf4+ 46.Kg2 Qxg5+ 47.Kf2 Qg3+ 48.Ke2 Qg2+ 49.Kd1 Qxa2 also wins) 46.Kf2 Be3+ 47.Kf1 Qf3+ 48.Ke1 Qf2+ 49.Kd1 Qf1+ 50.Kc2 Qc1+ 51.Kb3 Qc4+ 52.Kb2 Bd4+ 53.Kb1 Qd3+ 54.Kc1 Be3+, and White loses his queen (with mate soon to follow).
