A stunning Ding Liren blunder under time pressure gifted Gukesh Dommaraju a decisive result in Sunday’s Game 11 of their world title match, leaving the Indian challenger on the brink of history with a 6-5 lead and three contests remaining.
The fireworks came early as Gukesh, playing as white, opened with 1 Kf3 while Ding responded with the ultra-committal 2...d4, the unbalanced Reti opening auguring a sharp, exciting game after Saturday’s tame draw.
The 32-year-old reigning champion from Zhejiang province spent more than 38 minutes pondering his response to 4 e3 (4...Nf6), then another 22 minutes on his fifth move (5...Bg4), falling more than an hour behind on the clock. The position after seven moves appeared to be unique in the recorded history of chess.
But Gukesh soon joined his foe under time pressure, exhausting more than an hour on his 11th move. That was before the inaccuracy 15 Rd1 left him with no easy way to coordinate his queenside and facing an ominous time crunch, down to less than 25 minutes to make 25 moves before the time control. But Gukesh played with pace and accuracy from there, aided by Ding’s inaccurate 21...Rd7.
The decisive moment came when Ding finally crack on his 28th move with seven minutes left on his clock with the blunder 28...Qc8??. Gukesh spotted it almost immediately, made the correct capture (29 Qxc6), before Ding resigned within seconds and quickly exited the playing hall.
“It’s a very difficult game for me,” Ding said.
The result set off scenes of jubilation outside the sound-proof booth and the nearby fan zone, where the crowds filled with many supporters of Gukesh have been largest on the weekends.
The fifth-ranked Gukesh, an 18-year-old native of Chennai, is bidding to 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.
Ding entered the scheduled three-week match having gone 28 classical games without a win, dropping to 23rd in the world rankings and prompted the oddsmakers to price him as roughly a 3-1 underdog. But he sprang a major surprise in Game 1 by winning as black, dramatically ending a 10-month winless stream and delivering a riveting opening salvo.
Game 2 was a quiet draw, before Gukesh roared back with a win in Game 3. The fourth, fifth, sixth, seventh, eighth, ninth and 10th games were each draws.
The competition resumes on Monday with Ding playing as white in Game 11. Whoever reaches seven and a half points first will be declared the champion in the world title match at Resorts World Sentosa, an island resort off Singapore’s southern coast.
