World Cup: Dubov, Esipenko, Grebnev knock out Pragg, Keymer, MVL

11/13/2025 – Thursday's tiebreakers at the FIDE World Cup in Goa saw several high seeds eliminated, including Praggnanandhaa Rameshbabu, Vincent Keymer and Maxime Vachier-Lagrave, who were knocked out by Daniil Dubov (pictured), Andrey Esipenko and Aleksey Grebnev respectively.

Game of the Week #697: Gukesh vs Svane

11/13/2025 – Only very strong players are left at this stage of the World Cup. Germany is doing great with still four top grandmasters at the final 32: Vincent Keymer, Matthias Bluebaum, Alexander Donchenko and Frederik Svane. The latter most impressively beat World Champion Gukesh, from India, in India, with the black pieces in the classical part of their mini match, which of course needs to be our Game of the Week. It is striking how Frederik sticks to his own active style against everyone. | Merijn's show is available on-demand with a ChessBase Premium Account. You can register a Premium account here.

Keymer's magic

11/12/2025 – In his best games, Vincent Keymer’s chess sense seems almost magical. In the second game of round three of the World Cup in Goa, he had Black against Indian grandmaster Pranesh M. After 29 moves, five of his six remaining pieces had retreated to the back rank — yet Black already stood better. Only twelve moves later, as if by sleight of hand, Keymer's pieces controlled the queenside, the kingside and the centre, breaking through into White’s position. It was an important and impressive victory for Keymer, who advanced to round 4 of the World Cup. | Photo: Michal Walusza

40 years ago: Kasparov becomes World Champion

11/11/2025 – On 9 November 1985, Garry Kasparov defeated Anatoly Karpov in the 24th game of their World Championship match and became the 13th World Chess Champion. It was the conclusion of an extraordinary duel. The first match between the two, begun in 1984, had been abandoned after 48 games without a decisive result. In the rematch, the rules were changed: the match was limited to 24 games, and the reigning champion would retain the title in case of a tie. Across the two matches, Kasparov had to play a total of 72 games against Karpov to claim the crown — one of the most demanding World Championship battles in chess history. | Photos: Tass Archive
