World chess champion D Gukesh dropped out of the top 10 in the live chess rating after suffering a crushing defeat to world No 30 Jorden van Foreest in the third round of the ongoing Prague Chess Festival Masters 2026. While Van Foreest moved into a four-way tie for the first spot along with Nodirbek Abdusattorov, Nodirbek Yakubboev and David Navara with two points each, Gukesh finds himself among the bottom pack with one point from three matches.

The latest defeat to world No 30 has set alarm bells ringing for world champion Gukesh, who is ranked ninth in the official list but has slipped to 13th in the live ratings in a year in which he will defend his world crown.

Gukesh’s poor form raises concerns 

Known for his dogged resistance and insane calculation on the board, the 19-year-old Gukesh has been having a rather unimpressive 2026 after a poor 2025, where he did not win a single tournament. Earlier this year at the Tata Steel chess tournament, Gukesh finished ninth among 14 Grandmasters. He also suffered defeats against Anish Giri and Matthias Bluebaum in Wijk aan Zee, two players who will be competing in the upcoming FIDE Candidates 2026 to be a challenger for the Indian Grandmaster’s world title.

It’s high time Gukesh quickly rediscovered his form, else it will become extremely difficult for him to have the required confidence to defend his world crown.

On Friday in Prague, Gukesh played an erroneous game against Jorden van Foreest, but nothing can explain not pressing the clock hard enough after the 36th move. His blunder cost him valuable time as he lost 45 seconds after playing his move and the Dutch Van Foreest got the chance to plan his move on the world champion’s time.

How Van Foreest defeated Gukesh

Coming to the game, Gukesh made his biggest blunder on move 17 with the black pieces as he played Qb8 when Nd7 was the best move. But even more impressive was the rook sacrifice by Van Foreest for a knight on d4. This allowed the Dutch chess player to take full control of the match and soon went a pawn up.

After another blunder 35…Kd3, a defeat for Gukesh became inevitable, and he was forced to resign after 48 minutes – a first win over the world champion for Van Foreest.

“Of course I’m super-happy. Not only is it my first win against a world champion, but also my first win against Gukesh. Even before he was world champion I played him a couple of times, but I never won against him and he won against me several times,” Van Foreest said.

While explaining his rook sacrifice, he said: “He was looking rather calm, and I was like, am I missing something? I didn’t see it, so I thought I had to go for it.”

“I’m up a pawn, there’s really no risk—in the worst case it’s a draw, and for him the defense will be always very difficult, even with best play, so I was happy,” said Van Foreest.
