SummaryRounds 1–3The first round saw Anand beat Topalov after mutual blunders around move 20, then again around move 40, to get an early lead as all other games were drawn, two of them right at the 30-move mark.
Round 2 went similarly, with two of the 3 draws occurring in 30 moves, while Nakamura missed a tactic against Karjakin and played a large unforced blunder on move 29, costing him the game.
Round 3 saw both leaders draw, as Giri made two knight sacrifices before forcing an early draw by repetition against Karjakin, while Anand had a nagging edge against Caruana that eventually evaporated. Meanwhile, Aronian joined the leaders by beating a very off-form Topalov as Black, while Svidler as Black out-prepared Nakamura in a complicated Semi-Slav line to move 25, but failed to convert a pawn-up endgame in which Mark Dvoretsky questioned his lack of killer instinct.
Rounds 4–6After a rest day, two of the leaders faced each other in Round 4, with Karjakin as White choosing a passive opening and coming up with an early novelty against Anand, and then saddling him with hanging pawns. He then switched to a pressing endgame against Black's pawn weaknesses, and soon after the time control an Anand miscue led to his immediate resignation. This was Karjakin's first career victory over Anand in classical time controls.
Nakamura and Giri drew in just over an hour in 30 moves in a game that might have been completely pre-analyzed, while Svidler and Aronian drew a rook ending at the time control. The game between Caruana and Topalov saw a Giuoco Pianissimo opening, before Topalov opened up the position and later blundered in time pressure, but Caruana spoiled a large advantage right after the time control by miscounting the pieces, and in the end a double rook endgame was drawn.
In Round 5, all the games were drawn, three of them at move 30 and the other at move 40. Unlike the previous round, when Karjakin himself had hanging pawns, it did not matter and he drew comfortably.
Round 6 saw Svidler losing out of the opening against Anand, while Karjakin held a materially imbalanced position to a draw against Caruana. The Topalov-Giri game saw a practical novelty already at move 3, with a resulting drawn knight endgame after the 60-move mark. In the game Aronian-Nakamura, Aronian nurtured an advantage for some time, but the endgame appeared to be drawn. But on move 74, Nakamura made a fingerfehler and touched his king, forcing him to make a losing move. The incident was controversial as Nakamura initially tried to claim j'adoube, the international term to convey that one intends to adjust the piece, not move it. This win brought Aronian into the lead with Karjakin, with Anand just behind, going into the second rest day.
Rounds 7–9After the second rest day, the two leaders, Karjakin and Aronian, faced each other in Round 7. As White, Karjakin played an aggressive opening, but Aronian was able to neutralize it and the game ended in a draw. Svidler got a winning position out of the opening against Caruana, but was not able to convert it, resulting in a draw. Giri and Anand drew an uneventful game as Giri did not feel ready to challenge Anand’s preparation. Nakamura defeated Topalov in a complex game featuring a bishop sacrifice from Topalov.
In Round 8, Aronian and Giri made an uneventful draw. Topalov and Anand also drew, with Topalov saying he did not expect Anand to repeat the same opening he played against Giri in the previous round. Svidler and Karjakin played a sharp back and forth game which eventually ended in a draw. Caruana defeated Nakamura in an opposite-side castling game coming out of the Anti-Berlin.
In Round 9, Karjakin played his fourth Queen’s Indian game against Nakamura, keeping his undefeated plus two score with a draw. Topalov had good winning chances against Svidler but could not capitalize, resulting in a draw. Giri and Caruana played a combative game in which Giri had a large advantage, but could not convert in through the complications, resulting in Giri’s ninth draw of the tournament. Anand beat Aronian in a rather one-sided game, taking Aronian’s shared first place with Karjakin as a result.
Rounds 10–12Round 10 saw three of the four games start with the same opening position after six moves. The one game that did not, Karjakin vs Giri, ended in an uneventful draw. Both Svidler vs Nakamura and Aronian vs Topalov also ended in draws. Caruana, playing White against Anand, unleashed a powerful opening novelty, obtaining a tremendous advantage and winning the game as a result. With the win, Caruana replaced Anand as the tournament co-leader alongside Karjakin.
In Round 11, Giri got a promising position against Nakamura but had to settle for a draw after making a tactical oversight. Topalov and Caruana played a roller-coaster game which eventually ended in a draw. Svidler defeated Aronian with the Black pieces after Aronian overpressed a better position, effectively ending Aronian’s chances of winning the tournament. In the most important game of the round, Anand defeated Karjakin from an equal-looking endgame, making Anand and Caruana the new leaders of the tournament.
In Round 12, Aronian, playing with Black, had a winning rook sacrifice against Caruana, but could not evaluate it correctly. Aronian did not play it and Caruana was able to hold the game to a draw. Giri was pressing against Svidler with the Black pieces, but never got a serious advantage, resulting in Giri’s twelfth consecutive draw of the tournament. Nakamura, playing with White, crushed Anand in just 26 moves after outpreparing him in a complicated line of the English. Karjakin defeated Topalov with White in a complicated Najdorf, putting him back in shared first with Caruana.
Rounds 13–14In the penultimate round, Nakamura beat Topalov in a smooth game with Black to get back to a 50% score. Anand and Giri played an adventurous game, but neither player could make the most of their chances and the game ended in a draw. Aronian put pressure on Karjakin but could not break through Karjakin’s tenacious defense, resulting in a draw. Caruana vs Svidler reached the theoretically drawn rook and bishop vs rook endgame. On move 102, Svidler made a decisive mistake but Caruana did not punish it, allowing Svidler to save a draw through the fifty-move rule. Going into the final round, only Karjakin or Caruana could win the tournament.
The tournament winner was decided in the final round game between Karjakin and Caruana. Before this round, these were the only two players who could win the tournament, having 7.5 points each. For Caruana to win the tournament, he needed to win the game, or draw and rely on Anand to win with Black against Svidler.
Caruana chose the Sicilian Defence, signaling his intention to play for a win. Karjakin continued with the Open Sicilian. Caruana took the initiative and it appeared as if a win for Black could be possible. His pawns were attacking the White king that had castled on the queenside. However, his own king had not castled and became a requirement for the defense of three pawns on d, e, and f file. Eventually, this weakness led to the collapse of the Black defense. Caruana resigned on move 44, making Karjakin the winner and challenger for the World Chess Championship 2016.
Broadcast restrictionsIn a matter that dominated early discussion of the Candidates, Agon controversially tried to claim that only approved broadcasters were able to put forth the game moves in real time. However, a similar restriction was attempted by Sofia organizers first for the Topalov-Kamsky match in 2009 and then the World Chess Championship 2010, with the end result that ChessBase was found non-culpable in a resulting lawsuit. The judge in that case took only half an hour to reject all demands from the Bulgarian Chess Federation, while ChessBase relied on the legal definition of a database. The most important aspect was that the judge did not agree that a chess game can be seen as a database, and therefore the BCF could not refer to their rights as database producers. The president of the BCF, Silvio Danailov, estimated the loss at 1 million euros in a Forbes interview, though they had only asked 15000 euros from ChessVibes for retransmission rights, and crucially only spent 8000 euros themselves, which the judge found insufficiently substantiated as a realistic amount toward a database endeavor.
Agon's legal position on move retransmissionAgon produced a legal position white paper, asserting that chess fans should have to agree to terms and conditions that include not re-transmitting the moves elsewhere, before being allowed access. This is in line with a 2011 European Chess Union memo that produced a legal opinion from Morten Sand, indicating that contract law formed a superior basis for exploiting the chess audiences, with the expectation that viewers could be made to bear 75 euros for the world championships, so that "the financial upside is huge" to generate 750000 euros.
Commentary from affected partiesThe Bulgarian website Chessdom had the strongest editorial on the matter, calling Agon's decision a multi-level blunder, even pointing out that Agon's decision actually violates Section 4.7.3.6.4.1 of the . However, this item is enforceable only between Agon and FIDE. Their main thrust though, was:Millions of fans will not learn about this year’s Candidates matches because of AGON’s policy. Many will miss the live coverage and only learn about the games after the tournament is over, when Carlsen’s challenger is known. What is the commercial value of that? Can you calculate how much are the lost benefits for the sponsors of the event? And for the hosts? And for the players? And for the sponsors of the players? Additionally, Mihailov noted the lack of equality of arms in Agon's legal salvo: "With lawyer white paper threats you have cut any journalist’s right to properly cover the Candidates. While being with the law on their side, no sane journalist will risk losing time and/or money arguing with an organization." Two more articles were swiftly published, including a polemic against AGON's monopolistic agenda. Chessdom in the end did not broadcast live moves.
Chess.com had an article on the matter, couching their Candidates preview with "a remarkable decision by the organizers might well be the biggest story here", while noting that it personally "lacks the technology and always relies on volunteers to bring grandmaster games in Live Chess."
In the Norwegian press, Magnus Carlsen was nonchalant toward the kerfuffle, saying that everyone could just watch the Agon broadcast, with their comments and computer evaluations. However, NRK will also have move-by-move coverage on NRK.no, according to their own interview with him.
ChessBomb published that it would not use the Agon site due to non-agreement with terms and conditions, and asked for volunteers to seed their Tor setup. Implicitly, this relied on the fact that the clickwrap license presented by Agon may not in fact be valid in every viewer locale, so by allowing information to be obtained and retransmitted without contractual obligation. However, after a successful Round 1 broadcast, during Round 2 their live move transmissions were essentially halted, with looming legal threats.
Resulting effectChessBase ended up taking the threats seriously, which could have been to the dismay of Agon, as the official commentators were trying to use their software in Round 1. Instead, they had to switch to manual entry from ChessBomb. Alleged violators included not only ChessBomb and Chessdom, but also ICC, Chess24, and Der Spiegel. Although the Terms and Conditions mention New York state law as applicable to those who signed up, Merenzon sent a cease and desist letter that invoked 10 years imprisonment under Russian law. The specifying of choice of venue and choice of law in a contract of adhesion can also be in dispute.
Agon also impeded the credentials of Salim Fazulyanov, allegedly as retaliation against his website Kavkaz-Chess.ru for being the first Russian site to publish Chessdom's open letter.
Eventually Agon's own worldchess.com editorial staff broke ranks, declaring that an embargo was not the way to go, but a show. The main argument is: holding all the trumps like live video and exclusive interviews with players should be enough, without resorting to legal blusterings. Before Round 2, Agon partially relented, dispensing with its presumptory 2-hour PGN embargo, designating the game's end instead.
In round 1, the moves were carried live without restriction by official partner NRK. About 45 minutes into second round, the NRK live move transmission became suspended, causing other sites to also experience confusion. According to reporter Tarjei Svensen on Twitter, Agon was actively pursuing lawsuits against ChessBomb, Chess24, ICC, and ChessGames.com, with the chilling effect of causing them to essentially suspend activity. The Norwegian online newspaper site VG Direkte initially stayed active, but then also suspended activity. Der Spiegel continued its live ticker of Aronian-Anand analysis throughout.
After Round 2, Agon officially announced its rumored legal action against the above four broadcasters.
The Guardian newspaper covered an exposé of the ruckus, noting that Agon's tactics may be hoping to at least scare off its rivals and keep the big prize to itself. Vladimir Kramnik was quoted from an ensuing interview as saying: "If you want to make chess professional, if you want to help chess to grow, you have to understand very clearly that the organiser of any chess tournament has full transmission rights. Because the organiser has invested a lot of money and effort to organise the tournament, morally and legally they have full rights over the live transmission." Kramnik contended such control was the way football, tennis and other sports had become successful, and by doing the same, chess could jump to a totally different level. He also imposed his own view upon any end user's opinion of the coverage, declaring that "no one is suffering" from Agon's decision. Top organizer Stuart Conquest was also quoted: "However you look at it, pretty clear that start of Candidates has been a PR disaster for organisers / Agon / FIDE."
Round 3 and beyondChessBomb's whole site went down 10 minutes into Round 3 without any moves having been shown, while Chess24 intermittently carried the moves of two of the four games in the early going. Chessgames.com similarly had Giri–Karjakin, while Der Spiegel had the Anand–Caruana game on their live ticker. After rectification 10 minutes later, ChessBomb had all three of the above-mentioned games, and Chess24 quickly added Anand–Caruana also.
By round 4 the immediate frenzy appeared to have dissipated, as Grandmaster David Smerdon was given an all-clear from Agon to run a live blog. However, the main sites were still lagging in their relays by about 20–25 minutes during the opening moves. The sites NRK and VG Direkte relayed the games with a delay of about 20 minutes. Later, at approximately an hour into the games, the alternative feeds were nearly keeping pace with Agon's site, though some slowdown sporadically remained. Agon boasted that PGNs were now going to be available as Flash Reports within minutes of the finish of each game. Their own onsite live commentators were still having problems getting the moves to the games at some junctures. Renowned trainer Mark Dvoretsky was deeply unsympathetic to Agon's position, particularly as the official site was so inconvenient to use, and he also mentioned the privacy issues with the necessity of registering there.
After the tournamentAgon, through a company called Turnir Pretendentov LLC attempted to sue eLearning Ltd. for 20 million roubles, for the live broadcasting of the moves of the Candidates Tournament on chess24.com. Agon's legal claim was rejected in its entirety on 25 October 2016. Agon are also suing ChessGames and ChessBomb; the final hearings in these cases are due to take place on 17 January 2017 and 28 February 2017 respectively.
