Ding Liren’s world championship match with Indian teenager Gukesh Dommaraju remained on level terms with an uneventful 42-minute draw on Friday in the fourth game of their $2.5m meeting in Singapore.
The 32-year-old reigning champion from Zhejiang province, playing with the white pieces for the second time, caused the challenger some initial discomfort by switching to the offbeat Zukertort Opening (1 Nf3) and continuing the surprise with 5 Ba3.
But Gukesh steered the contest into a tense yet balanced middlegame, countering Ding’s queenside expansion (11 b4) with 11…c6, as both kingsides remained stable and neither gained a decisive edge.
After 24 Nxe4 and subsequent exchanges, the game transitioned into an equal rook endgame. Gukesh’s 25...c5 opened the position, but Ding countered effectively with 28 Rc1. Both players activated their kings and maneuvered their rooks skillfully, but the position remained deadlocked until a draw by repetition immediately after the first time control.
“It was not a completely new line for me,” Gukesh said afterward. “I had seen it before somewhere. But it was a bit of a surprise. I was playing over the board from very early on, but I think I reacted well enough.
“At some point I felt like he had maybe some slight edge, but I quickly neutralized it and then was kind of pushing, but [saw] it should never be anything serious for either of us.”
Ding came into the first defense of his world championship having gone 28 classical games without a win, a dreadful run of form that saw him drop to 23rd in the world rankings and prompted the oddsmakers to install him as roughly a 3-1 longshot in the match.
But he sprang a major surprise in Monday’s first game by winning as black, dramatically ending the 304-day winless streak. Game 2 on Tuesday was a tame 23-move draw, before Gukesh struck back on Wednesday with a win in Game 3. The three-time Chinese national champion arrived at the playing hall on Friday afternoon with both of his seconds for scheduled three-week match: the Hungarian Richard Rapport and Ni Hua of China.
“I had a rest day to recover from the tough loss,” Ding said. “I am in a very good mood. I chose this opening idea trying to surprise my opponent. It worked well, not so bad.”
An 18-year-old native of Chennai, the fifth-ranked Gukesh can shatter the record for youngest ever undisputed world champion held by Garry Kasparov, who was 22 when he dethroned Anatoly Karpov in their 1985 rematch in Moscow.
The match resumes on Saturday with Gukesh playing as white in Game 5. Whoever reaches seven and a half points first will be declared the champion in the world title encounter at the Equarius Hotel at the Resorts World Sentosa.
“I tried to play it safe [on Friday],” Ding said. “It turns out I got a little bit of an advantage. But the score is still balanced and there are more games to come.”
