The World Chess Championship 2023 was a chess match between Ian Nepomniachtchi and Ding Liren to determine the new World Chess Champion. The match took place in Astana, Kazakhstan, from 9 April to 30 April 2023, and was a best of 14 games, plus tiebreaks. Ding Liren won in the fourth tiebreak round, becoming the World Chess Champion.

The previous champion Magnus Carlsen decided not to defend his title against Ian Nepomniachtchi, the winner of the Candidates Tournament 2022. As a result, Nepomniachtchi played against Ding Liren, who finished second in the Candidates Tournament.

After a 7–7 score tie in the classical time format, on 30 April, the game proceeded to tiebreakers with rapid time format. After a draw in the first three games, Ding Liren won with black in the final game of the rapid section to become the 17th World Chess Champion.

Ding Liren won €1.1 million ($1.4 million), 55% of the prize total. Ian Nepomniachtchi won €900,000, 45% of the prize total.

Carlsen declines to defend the title

The previous World Champion was Magnus Carlsen, who first won the title in 2013. To keep the title, Carlsen was periodically required to defend it in a championship match against a challenger, determined by a Candidates Tournament. Carlsen successfully defended the title in the world championship matches of 2014, 2016, 2018, and 2021. In December 2021, soon after the 2021 championship (against Ian Nepomniachtchi), Carlsen stated that he lacked the motivation to defend his title again, unless the challenger was Alireza Firouzja. Firouzja had risen to number two in the world rankings in 2021 at age 18. In April 2022, Carlsen again publicly stated that he was unlikely to play in the next world championship, this time without mentioning any potential opponent.

The Candidates Tournament 2022 concluded in early July 2022, with Nepomniachtchi its winner. FIDE and Carlsen were already in talks regarding the world championship match and its format. On 20 July, Carlsen announced that he would not defend his title. Therefore, the 2023 world championship match was between Nepomniachtchi and Ding Liren, the winner and runner-up of the 2022 Candidates Tournament, respectively, and Carlsen lost the title when the match concluded. After Carlsen formally confirmed his decision in writing, FIDE officially invited Ding to participate in the 2023 world championship.

Non-participation by the incumbent champion in the World Chess Championship is rare. For the World Chess Championship 1993, incumbent Garry Kasparov and his challenger Nigel Short broke with FIDE and organized the championship on their own terms. FIDE disqualified them and set up their own FIDE World Chess Championship 1993 with runner-ups Jan Timman and Anatoly Karpov, who won the match. This set up the 13-year period of split World Champion title 1993-2006. In the sub-period of 1999-2004, the FIDE Championship was held as a knockout tournament with 100-128 candidates: here Karpov refused to participate in 1999 due to the lack of privileges for him as incumbent champion, and 2002 FIDE champion Ruslan Ponomariov refused to defend his title in 2004 to protest against the preponderant role FIDE granted Kasparov in the re-unification process.

Before the split title period, the last reigning champion who declined to take part was Bobby Fischer in 1975. Fischer cited the format of the match at the time as the reason – the format was first-to-12.5-points, while Fischer wanted a first-to-ten-wins format. After FIDE declined to meet Fischer's demands, Fischer forfeited, and FIDE awarded the title to Fischer's challenger, Anatoly Karpov, the winner of the Candidates Tournament. The only time from the first World Chess Championship 1886 to 2023 that an undisputed world championship was played without the defending champion was the 5-candidate Championship tournament in 1948, because the previous champion Alexander Alekhine had died in 1946.

The challengers were Ian Nepomniachtchi and Ding Liren, who qualified as the winner and runner-up, respectively, in the Candidates Tournament 2022, which began on June 16 and ended on July 5, 2022. Ding qualified for the Candidates Tournament 2022 through his rating, as a replacement for Sergey Karjakin, who had been barred from playing by FIDE due to his comments supporting the Russian invasion of Ukraine. Nepomniachtchi had previously challenged world champion Carlsen in the previous championship in 2021.

Championship match

Organization

The match took place in Astana, Kazakhstan, from 9 April to 30 April 2023 at the St Regis Astana Hotel.

The prize fund was €2 million. It would have been split 60% vs 40% between the winner and the runner-up had either player scored 7½ or more points in the classical portion of the match. As the match was tied after 14 classical games, the prize fund will be split 55% vs 45% in favor of the winner of the tiebreak. The main sponsor for the event was Freedom Holding Corp., a Kazakhstan-based Russian investment company with ties to the Central Asian region, with chess training app Chessable, mining company LLP Tioline, and the Kazakhstan Chess Federation also sponsoring the event.

The chief arbiter was Nebojša Baralić from Serbia, while the deputy arbiter was Gerhard Bertagnolli from Italy.

The first move of each game was ceremonially performed by guests invited by the organisers:

Match regulations

The time control for each game in the classical portion of the match was 120 minutes per side for the first 40 moves, 60 minutes for the next 20 moves, and 15 minutes for the rest of the game, with a 30-second increment per move starting with move 61.

The match was best of 14 games; a score of at least 7½ would win the world championship. Due to the score being equal after 14 games, tiebreak games with faster time controls were played:

• A match consisting of 4 rapid games with 25 minutes per side and a 10-second increment starting with move 1 will be played. If a player scores 2½ points or more, he would win the championship.
• If the score had been equal after the rapid portion, a mini-match of two blitz games would have been played, with a time control of 5 minutes per side and a 3-second increment starting with move 1. If a player scored 1½ points or more, he would win the championship. If the blitz mini-match was tied, another mini-match with the same conditions would be played to decide the winner of the championship. A drawing of lots would take place before each mini-match to decide which player plays with the white pieces.
• If both blitz mini-matches were tied, a single game with a time control of 3 minutes per side and a 2-second increment starting with move 1 would be played, and the winner would win the championship. A drawing of lots would decide which player plays with the white pieces. If this game was drawn, another blitz game with reversed colours would be played with the same time control, and the winner would win the championship. This process would be repeated until either player wins a game.

Players were not allowed to agree to a draw before Black's 40th move. A draw claim before then was only permitted if a threefold repetition or stalemate has occurred.

Previous head-to-head record

The pre-match head-to-head score between Nepomniachtchi and Ding in classical games was: 3 wins for Nepomniachtchi, 2 wins for Ding, with 8 draws. Their most recent pre-championship games, during the 2022 Candidates tournament, resulted in one win to Nepomniachtchi and one draw.

Schedule

The games began at 15:00 local time (EKT), which was 09:00 UTC.

Colours were drawn at the opening ceremony using a robotic arm assisted by artificial intelligence. Nepomniachtchi received the white pieces for the first game. Colours alternated thereafter, with no switching at the halfway point. Colours for the rapid games were drawn at the press conference after game 14: Ding received the white pieces for the first game.

If the match had ended before 14 games (because one player reached 7½ or more points), the closing ceremony would have been conducted either on the day of the last game or the day after. Had the match ended with the 14th classical game, the closing ceremony would have been held on 30 April. The closing ceremony will be on 1 May, due to the score being tied after 14 classical games.

Possible leak of Ding Liren's preparation

A few minutes after the beginning of Game 8, two anonymous Lichess accounts (FVitelli, opqrstuv) were posted to Reddit that were rumored to belong to Ding Liren and his training partner Richárd Rapport. Games between the accounts were discovered that followed the openings of games 2, 6, and 8 of the match. An identically named account on Chess.com was identified playing similar openings with lines that follow the games against a user identifying to be from China, which shortly changed its username to "ggwhynot" after the rumors. Many commentators considered the rumor to be accurate, with Hikaru Nakamura stating that "There's zero chance these aren't their accounts." If true, this could potentially reveal crucial opening preparation for upcoming games and significantly disadvantage Ding, as Nepomniachtchi may exploit the opportunity to prepare for these openings. When asked during the post-game press conference about the rumors, Ding said, "I don't know which games you refer [to]." After game 10, Nepomniachtchi was asked if the leak affected his preparation, responding, “My team took a look. I wouldn’t say it should be as hyped as it actually is. I am still more or less doing what I was going to do. We didn’t change it too much, I think.”

Position after 25.Qd2. Here Ding (Black) opted to advance a pawn with 25...c6?!, rather than initiate the trade of rooks on the d-file. Anish Giri and Jan Gustafsson disapproved of the move as it created a long-term weakness of Black's queenside pawn structure. After the continuation 26.Rxd8+ Nxd8, Nepomniachtchi (White) countered with the move 27.Qf4!, giving White a near-winning advantage as Giri speculated that Ding overlooked the threat of 27...Qb7 28.Qc7!, rather than the move 28.Qb8.

The first game of the match, a 49-move draw, was played on 9 April. Nepomniachtchi began with 1.e4, with both players quickly playing into the Ruy Lopez. Nepomniachtchi surprised commentators with the rare sideline 6.Bxc6 dxc6 7.Re1, and, in the words of Erwin l'Ami, obtained a "risk-free position and long-term structural edge". Nepomniachtchi missed a tactical opportunity early with 14.Nf5 (14.h3! would have set up 14...Qxd4? 15.Nd5!!), but the game otherwise stayed mostly level until the move 25...c6?!, with Nepomniachtchi quickly playing 26.Rxd8+ Nxd8 27.Qf4!, forming a battery towards Ding's weakened queenside and gaining the initiative. With Ding low on time, a few inaccuracies by Nepomniachtchi (30.Ng3 and 31.f4) allowed Ding to force a trade of queens and consolidate his position, reaching an equal endgame by move 38. A draw was agreed on move 49 after just under five hours of play.

Ding, in the post-game press conference, provided insight into his morale during and following the game: "I'm not happy; I'm a little bit depressed. During the game, I felt a flow of inconsistency. In the first part of the game, I couldn't concentrate and think about chess. My mind was full of memories and feelings. Maybe I couldn't calculate because of the pressure of the match."

Position after 11...Na5. Ding took 33 minutes to play 12.Nxf6+?! instead of 12.Nxc5, later identifying during the post-game press conference that the move weakened his position as the continuation 12.Nxc5 Bxc5 13.dxc5 Nd7 would have maintained Ding's advantage. Nepomniachtchi's aggressive response of 12...gxf6 13.e4? (much better was 13.dxc5 with chances to retain equality) 13...c4! consolidated a strong pawn structure and allowed his rook to occupy the open g-file.

The second game of the match, a 29-move win for Nepomniachtchi, was played on 10 April. After 1.d4 Nf6 2.c4 e6 3.Nf3 d5 Ding played 4.h3, a move that had never been seen before at master level. Nepomniachtchi said at the press conference that he initially wrote 4.g3 (a standard move which would have led into a Catalan) on his score sheet, before realizing 4.h3 had been played. Alexander Shabalov stated that "[4.h3] definitely comes from Richard Rapport, Ding's second", which Ding confirmed. Nepomniachtchi decided to play 4...dxc4 and treat the game as a Queen's Gambit Accepted, on the basis that White's h2–h3 is not particularly useful in that line. After playing most of his moves almost instantly, Ding took over 30 minutes to play the move 12.Nxf6+, later identifying the move as a critical moment, saying he had only looked at 12...Qxf6 and entirely overlooked Nepomniachtchi's response 12...gxf6. Ding's follow-up 13.e4?! was criticized for weakening his position; commentators recommended 13.dxc5 with approximate equality. Nepomniachtchi subsequently took over the initiative: his move 18...f5! was highly praised; it set the spectacular trap 19.exf5 Rxd4!! 20.Nxd4 (other moves avoid mate but lose material) 20...Rxg2+ 21.Kf1 Rxf2+! 22.Kxf2 Qh2+ 23.Ke3 Bh6#. Nepomniachtchi confirmed in the post-game interview that he felt that he was winning after 18...f5. Ding avoided this trap with 19.Bc2, which was nonetheless a concession—Ding's previous play seemed to be aimed at putting the bishop on f1. After 20.Bg5, Nepomniachtchi sacrificed an exchange with 20...Rxg5!, gaining the d-pawn and a dominating position after 21.Nxg5 Nxd4, and the e-pawn shortly afterwards. Already after move 20, Ding had less than 20 minutes remaining on his clock to Nepomniachtchi's 60, and he would need to play 20 more moves to reach the time bonus at move 40. Throughout the remaining moves of the game, Ding's time dwindled and his position worsened, until, after 29...e5, leaving the rook on d4 no safe squares, Ding resigned with less than a minute remaining on his clock.

Position after 27.Nb5. In the post-game press conference, Ding identified 27...d4!? as a way to attempt to press for an advantage, but decided it to be too risky. After 27...Nc7, the game was drawn by threefold repetition with 28.Nd4 Ne6 29.Nb5 Nc7 30.Nd4 Ne6.

The third game of the match, a 30-move draw, was played on 12 April. Commentators noted it represented a much improved performance by Ding. The game, a Queen's Gambit Declined, followed a game which Ding had previously drawn as Black against Anish Giri in an online rapid game in 2022 until 17.N1e2. Nepomniachtchi later stated that he had looked at the game prior to the round. Ding identified 21...Nxd7 as a critical moment where he began to play for a win, but chose to invite a repetition after 27.Nb5 with 27...Nc7. In the post-game interview, Ding stated he had considering 27...d4 as a potential move to continue playing for a win, but decided it would have been too risky. The game was drawn by repetition shortly afterwards.

At the post-game press conference, Ding stated, "I was not happy with the result. I was trying to play for a win at some point, but I couldn’t find a way to break through. So, I think a draw is a decent result for both of us." Nepomniachtchi made comments to the same effect, remarking that "The Queen's Gambit Declined is a very solid opening, so you're not going to achieve much. The most common case is when both sides play reasonably. It is hard to disrupt the equality."

Position after 28...Nd4?. Ding responded with 29.Rxd4! cxd4 30.Nb3, with the knight ready to win back the d-pawn. The knight was stronger than a rook under the circumstances of the position, due to White's space advantage and the closed state of the board.

The fourth game of the match, a 47-move win for Ding, was played on 13 April. The game began with an English Opening, Four Knights Variation. Nepomniachtchi's 9...Nf4 followed an earlier game won by Ding's second Rapport, leading Anish Giri to speculate that he had confused some of his preparation. This was later confirmed by Nepomniachtchi in the press conference. 14...Na5 was also inaccurate, as the knight would have a difficult time getting back into play while Ding created a strong central presence. Ding made the dynamic decision to sacrifice a pawn with 15.c5 in order to create an advanced pawn center. 23...f6 was a move Nepomniachtchi later called "unnecessary"; it allowed Ding to play 24.e6, giving him a passed e-pawn and a strong pawn chain, but in return Black was able to establish the knight on a strong defensive square at d6. Nepomniachtchi was still in the game until he blundered with 28...Nd4?, a decision former world champion Viswanathan Anand described as "insane". Ding made the strong exchange sacrifice 29.Rxd4!, and after 29...cxd4 30.Nb3, the knight is ready to dominate the black position from d4. Ding said he originally considered 29.Qd3 as a response, but found the winning move after thinking for just over a minute, while Nepomniachtchi confirmed that he did not see it until it was played. Even though the position was completely lost for Black, Nepomniachtchi played on, with Ding precisely converting his advantage. Nepomniachtchi eventually resigned on move 47, bringing the match score back to equality.

Position after 38.Rg4. The solid-looking move 38...f6 would run into 39.Nh4, with 39...gxh4 40.h6! destroying the black position, while any other move in response would allow the knight to get into the incredible outpost on g6. Rather than invite this, Ding played 38...Ra8, giving back the pawn with 39.Nxg5.

The fifth game of the match, a 48-move win for Nepomniachtchi, was played on 15 April. Nepomniachtchi was praised by commentators for his opening preparation, with many noting that he spent very little time making his moves until move 23, a time advantage which only grew as the game progressed. Anish Giri criticized the moves 19...Bd8!? and 20...Ne7!? by Ding, calling it "the most uncomfortable setup". Ding would later state, "I think the critical moment is that I should have played 29...Qf6 instead of 29...Nxf5." Commentators stated that 29...Nxf5 was not a poor move on its own, but 30...Qf6 was the mistake, suggesting that 30...Qd7 would have held the equality. Nepomniachtchi quickly launched a kingside attack, playing the pawn break 37.g5!, to which Ding's response 37...hxg5 was considered "losing completely" by Giri. After 38.Rg4, the natural-looking 38...f6, defending the pawn, would have run into 39.Nh4!, where 39...gxh4 40.h6! decimates the black position. 38...Ra8 was instead played, allowing Nepomniachtchi to regain the pawn with 39.Nxg5. Nepomniachtchi converted the positional advantage precisely, with the move 48.Rh6 convincing Ding to resign after 15 minutes of analyzing the position.

Commentators suggested that 27...Rxe5 28.dxe5 Qd8! would have given Nepomniachtchi an easier position to defend, as capturing the bishop with 29.hxg6? would have allowed perpetual check with 29...Qd1+ 30.Kh2 Qh5+. Instead, Nepomniachtchi played 27...Bc2?!, which allowed Ding to consolidate an advantage. Nepomniachtchi suggested 27...Bd3 as well, a move that would have led to a defendable though not equal position. a b c d e f g h 8 8 7 7 6 6 5 5 4 4 3 3 2 2 1 1 a b c d e f g h Position after 40...Rf8. Here Ding played 41.d5 after having thought for nearly 20 minutes. Despite not being the best option according to the chess engines, Ding would later finish the game by threatening the queen sacrifice 45.Qxg8+ Kxg8 46.Ra8+ Kf7 47.Rf8#, with the pawn on d5 preventing the king from escaping to e6. David Howell described the combination as "one of the most beautiful finishes to a world championship game in history".

The sixth game of the match, a 44-move win for Ding, was played on 16 April. Ding played the London System, making this game the first time it has appeared in a World Championship match. Despite this, Nepomniachtchi said that he did expect to see it at some point. After 14...Nd7 15.Nxd7 Qxd7, 16.a5! fixed Nepomniachtchi's queenside pawn structure, giving the white position a small edge. With a lack of active plans, Nepomniachtchi began to prepare the pawn break 22...e5. Ding mentioned that his initial plan was to play 23.b4, a move that would have invited less counterplay than the game move, 23.Rb3. Despite Ding being much lower on time, it was Nepomniachtchi who allowed his opponent to consolidate his slight edge. 27...Rxe5 28.dxe5 Qd8! would have allowed Nepomniachtchi to fight on, as 29.hxg6? would allow him to force a draw by perpetual check via 29...Qd1+ 30.Kh2 Qh5+. Instead of this, 27...Bc2 was played, allowing Ding to win the b7-pawn. 32.Rc5? was a hasty move that could have let Nepomniachtchi back into the game if he found 32...Qxc3; however, 32...Qc1+ was played, giving the initiative back to Ding. As the players reached the time control, Ding spent 20 minutes on the move 41.d5, taking away the e6-square for a mating net. After 41...a2 42.Qc7 Kh7 43.Ng6 Rg8 44.Qf7!, Nepomniachtchi resigned, as the threat of 45.Qxg8+ Kxg8 46.Ra8+ Kf7 47.Rf8# is unstoppable.

On the game, Nepomniachtchi would state, "I played one of my worst games ever. Every move was bad… 27...Bd3 instead of 27...Bc2 was better, but even that was unfortunate." When asked about the frequency of decisive games in the match, Nepomniachtchi declined to answer, while Ding responded jokingly, "I guess we are not as professional as Magnus [Carlsen]."

Position after 32.gxh4. Ding spent most of his remaining 5 minutes on the move 32...Rd2?, which allowed Nepomniachtchi to equalize, whereas 32...Be5 would have been much better, allowing Ding to have long-term pressure. After the natural 33.Re2, and with only 44 seconds on the clock, Ding played 33...Rd3? (mandatory was guarding the pawn with 33...Rd5, or giving check first with 33...Rd1+ 34.Kg2 Rd5), and after 34.Qxc5 Nepomniachtchi had a decisive advantage.

The seventh game of the match, a 37-move win for Nepomniachtchi, was played on 18 April. In reply to 1.e4, Ding deviated from his usual 1...e5, surprising his opponent and the commentators by opting for the French Defence, an opening last seen in a world championship match in 1978. Ding later confirmed in the press conference that he had "half-jokingly" suggested the French to his second, Richard Rapport, who then "insisted" that Ding play the opening. Nepomniachtchi chose 3.Nd2, the Tarrasch Variation. During the middlegame, Ding absorbed Nepomniachtchi's early pressure with accurate defence; however, by move 19 he was running low on time, having only 26 minutes to reach the time control with 21 moves to go. Despite this he found the strong exchange sacrifice 22...Nxf4! 23.Bxf4 Rxf4! 24.Rxf4 Bxe5, which gave him a strong bishop pair and some initiative; at this point commentators believed he had a slight advantage. With less than six minutes remaining on the clock for nine moves, Ding spent five minutes on the move 32...Rd2? (32...Be5! was best) which relinquished the advantage. He then blundered an important pawn after 33.Re2 Rd3?. Nepomniachtchi now had a winning position, and Ding resigned on move 37 with just 3 seconds left on his clock.

Position after 31...Qh4. This move was simultaneously described both as "brilliant" and a "bluff". Ding could have won after 32.Qxd8, but had to carefully calculate whether this allowed perpetual check beginning with 32...Qe4+; Rafael Leitão identified the critical line as going all the way to move 43. Under time pressure, Ding could only "briefly check the line", and chose 32.Kd1?, losing most of his advantage.

The eighth game of the match, a 45-move draw, was played on 20 April. In response to the Nimzo-Indian Defence by Nepomniachtchi, Ding opted for 5.a3, the Sämisch Variation, inciting Nepomniachtchi to double his c-pawns with 5...Bxc3+ 6.bxc3. The move 12.h4! was given praise, with Ding temporarily giving up a bishop for an open h-file and a strong attack. Ding quickly gained the advantage, having a passed d-pawn and a strong g-pawn. As Ding began to pressure the black position, Nepomniachtchi blundered with 22...Bxe4??, giving him a completely losing position. As Ding pressed his advantage, Nepomniachtchi played 31...Qh4!?, leaving his rook en prise, but appearing to threaten a draw by perpetual check; Nepomniachtchi would later call it a "bluff", as White can escape perpetual check and win after taking the rook, but this was very difficult to calculate at the board. Ding, under time pressure, was able to only "briefly check the line", as he described in the press conference, and instead opted for 32.Kd1?, losing much of the advantage. After a few more moves, Nepomniachtchi sacrificed his knight with 37...Nxf2! 38.Rxf2 e4 to return the game to equality, with both players rapidly trading down to a rook-and-pawn endgame and agreeing to a draw after 45.Re8.

Position after 26...Be6. Ding later said he anticipated the continuation 27.Bxb5 cxb5, sacrificing the exchange for connected pawns on the a- and b-files. Commentators and engines suggested this was the best move for Nepomniachtchi, but instead, he played 27.Bxe6, considered to be the safer, more human move.

The ninth game of the match, an 82-move draw, was played on 21 April. Against the Ruy Lopez, Ding chose the Berlin Defence. The first inaccuracy, 17...Rb8?! played by Ding, allowed Nepomniachtchi to build an initiative on the kingside; however, this initiative quickly faltered, with 23.Bg5? losing the advantage. Ding offered an exchange sacrifice with 26...Be6, allowing 27.Bxb5 cxb5, which would have given Ding connected passed pawns on the a- and b-files; however, Nepomniachtchi opted to trade bishops instead with 27.Bxe6, which was considered the "safer" move by commentators. Soon after, the players traded down into an endgame of rook, knight, and three pawns for White; versus rook, knight, and two pawns for Black. The pawn sacrifice 55...h3! by Ding received praise, splitting the remaining white pawns and rendering a draw nearly inevitable. Nepomniachtchi attempted to play on with his extra pawn, but a draw was eventually agreed on move 82.

Position after 10.Qg3. Ding would later say he expected Nepomniachtchi to defend his g-pawn with 10...g6, but after 10...Kf8, Nepomniachtchi was able to quickly steer the game to an equal endgame. Notably, Nepomniachtchi had played the same position in a Titled Tuesdays online tournament game, having the white pieces against Jose Gabriel Cardoso.

The tenth game of the match, a 45-move draw, was played on 23 April. Ding once again chose the English Opening to begin the game, following the same opening as game 4, until Ding chose 4.e4 instead of 4.e3. The move 9...Bc5 came as a surprise to Ding, who spent 11 minutes on his response. After Ding found 10.Qg3, he was once again surprised by the reply 10...Kf8, as he had expected 10...g6 instead. Although he was clearly out of his preparation, Ding navigated the position well and was able to maintain a slight advantage. He entered the endgame up a pawn, but Nepomniachtchi comfortably held the draw. The players finished the game with bare kings, only the second game in World Chess Championship history to end with bare kings on the board, the previous occurrence being game 13 of the 2004 Kramnik–Leko match.

Position after 18...Rb8. Nepomniachtchi could have pressed with 19.Qe2, but instead chose to liquidate into a drawn rook endgame with 19.dxc4.

The eleventh game of the match, a 39-move draw, was played on 24 April. Against the Ruy Lopez, Ding returned to the main line with 3...a6, as he did in game 1. Ding and Nepomniachtchi followed the same opening moves as their game in the 2020 Candidates Tournament until Ding played 8...Na5. 15...c4 was considered to be an intriguing move by Ding, inviting a double-edged game. However, instead of 19.Qe2, which would have preserved winning chances for either side, Nepomniachtchi chose 19.dxc4, inviting a series of exchanges that later led to a fully drawn rook endgame, with the players drawing by repetition only a few moves later.

Commentator Robert Hess identified this move as "winning on the spot" for White. In the post-game conference, Ding stated that he had calculated the best move, 34...f3, but Nepomniachtchi "did not play accurately" and chose a losing move instead. Ding replied immediately with 35.Rxe6, and Nepomniachtchi placed his head on the playing table and covered himself with his hands as he realised he had blundered and given away the equality.

The twelfth game of the match, a 38-move win for Ding, was played on 26 April. The game was a complex and error-ridden affair, with both players showing extreme signs of nerves. For the opening, Ding chose the Colle System, about which Nepomniachtchi would later say "I wasn't surprised." Through the double-edged middlegame, play remained relatively equal until Ding made the first mistake with 19.Bc2?, allowing Nepomniachtchi to build pressure on Ding's king and gain the advantage after a series of further inaccuracies by Ding. Despite the complexity of the position, Nepomniachtchi played 27...Rag8? quickly, which instigated a series of inaccuracies consisting of 28.Qc6? Bb8? 29.Qb7?? Rh6??, finishing with Ding finding 30.Be4, leaving the position equal. Fabiano Caruana commented on the sequence that "This is pure nerves at this point. It's no longer about chess." The game's newfound equality remained until Nepomniachtchi played 34...f5??, allowing Ding to take a free pawn with 35.Rxe6 and gain a powerful kingside attack. Nepomniachtchi spent 17 minutes thinking of a response to Ding's move, leaving him with 2 minutes and 36 seconds to reach the time control at move 40. Many commentators took note of Nepomniachtchi's body language at this point, associating "complete disbelief" to his expression. After a few more moves, Nepomniachtchi resigned, with Ding Liren equalizing the match with two games remaining.

Position after 21.Be4. In this position, Ding spent 25 minutes to play 21...Re5?!, drawing confusion from commentators and giving up the slight advantage he had gained. 21...Rb8 and 21...Qg5 were identified by Rafael Leitão as moves that would have held the advantage. When asked about the move in the post-game press conference, Ding said he had considered 21...Rb8, but chose 21...Re5 to defend the knight on d5.

The thirteenth game of the match, a 40-move draw, was played on 27 April. It began with a Ruy Lopez, Closed Variation, similar to games 5 and 11 of the match. 10.Be3 was the first deviation from theory, a move never seen before at master level. The position remained equal until 18.f3?! by Nepomniachtchi, which allowed Ding to play for the pawn break ...d5. After 19...d5 20.exd5 Nxd5, Ding held a slight advantage. Ding spent 25 minutes of his clock to play 21...Re5?!, giving up the advantage he would have had after 21...Rb8 22.Bxd5 (the knight cannot be allowed to come to f4) Bxd5 23.Qd2, where he has the bishop pair. Nepomniachtchi later gave Ding a chance for an initiative after 23.Ne2; however, Ding played 23...Qe7, blocking the bishop on f8, rather than the superior 23...Qe8. Ding sacrificed the exchange with 25...Rxe4, and the players quickly liquidated into a drawish endgame where Nepomniachtchi was up an exchange, but down a pawn. Ding would later mention he considered playing for a win with 36...Ke6, but decided against it as he "didn't want to play a dark ocean kind of position". The players chose to repeat moves shortly thereafter, ending the game in a draw.

Position after 12.Ng5

The fourteenth and longest game of the match, a 90-move draw, was played on 29 April. A win for either player would have resulted in winning the entire match and becoming world champion. Ding played 12.Ng5?!, which surprised many due to the fact that the knight could easily be attacked with 12...h6 (as in the game) and did not accomplish much, although the position was still near equality. Ding's 34.Ke2? was a mistake (34.Kd2! was accurate), but Nepomniachtchi relinquished his advantage with 36...e5?! (36...Rb3! was better), and with 38.b6! Ding liquidated into a drawn pawn-down rook endgame. Nepomniachtchi tried to create winning chances with 61...Kd7!, but Ding found the only drawing move 65.f4!. Nepomniachtchi was unable to make any progress and both players finally exchanged off the pieces and agreed to a draw at move 90.

Tie-break games

Tie-break games were played on 30 April.

Game 15: Ding–Nepomniachtchi, ½–½

The first game of the rapid tie-break ended in a 35-move draw. Ding steadily held the advantage for the majority of the game, especially after 21...Rd8?! by Nepomniachtchi. This advantage was soon lost after Ding played 23.Rb1?, however, returning the position to equality. After 26.Nb5 both queens were vulnerable and a trade of queens occurred with 26...Rxd2 27.Nxc7. Although Ding suffered from slight time trouble for a majority of the game, the players agreed to a draw on move 35.

Game 16: Nepomniachtchi–Ding, ½–½

The second game of the rapid tie-break was a 47-move draw. Like several other games of the match, it began with the Ruy Lopez opening. Nepomniachtchi gained a slight advantage after 13...Rb8. Nepomniachtchi's biggest advantage came after Ding played 20...Nd5?!, although Nepomniachtchi failed to play the correct move (21.Bg3) and instead played 21.exd6?!. The game consisted of nearly perfect play on both sides and ended in a draw.

Game 17: Ding–Nepomniachtchi, ½–½

The third game of the rapid tie-break was a 33-move draw and had perfect play by both sides. Starting on move 9 with 9...cxd4, Nepomniachtchi began trading pieces and going for a draw. After 10.Nxd4 Nxd4 11.Qxd4 Bf6 12.Qd2 Nf4 13.gxf4 Qxd2 14.Nxd2 Bxb2, three knights, a bishop, and two queens were traded off the board after just 14 moves. After trading off two minor pieces and the rooks, a repetition was imminent and both players agreed to a draw.

Game 18: Nepomniachtchi–Ding, 0–1

The fourth and final game of the rapid tie-break was a victory for Ding Liren, resulting in him winning the world championship. The game remained relatively equal for the majority of the game up until 48. h4??. After a repetition was threatened after 44. Qe4+ Kg8 45. Qd5+ Kh7 46. Qe4+, Ding instead played 46...Rg6 with only 1 minute and 23 seconds on the clock to Nepomniachtchi's 2 minutes and 39 seconds. The turning point of the match was reached after 47. Qf5 c4 with Nepomniachtchi's 48. h4??, failing to spot Ding's winning reply 48...Qd3!, which was played in just two seconds. Engine analysis showed 48. Qf4 was instead the only move to hold the draw. After 53...Rd6?? was played by Ding, the position slowly returned to equality until Nepomniachtchi blundered again with 59. Qc7??, after which Ding found the only winning move yet again with 59...Qg6. The game became completely losing for White after Nepomiachtchi played 63. Kf1??. Nepomniachtchi resigned after 68...Bxf4 as mate was possible (with perfect play, in just eight moves).
