Diving chess in South Africa
Hans Niemann (USA) became the Diving Chess Cape Town 2025 Champion on Thursday after beating Fabiano Caruana (USA) in the final of an underwater chess event held at the Silo Hotel in Cape Town, South Africa. Javkohir Sindarov (Uzbekistan), the recent FIDE World Cup winner, won the match for third place against Vidit Gujrathi (India). The event was the first ever Freestyle Diving Chess Championship.
Players made their moves on a small chess set placed 110 centimeters deep, on the bottom of the Silo Hotel’s beautiful rooftop pool. Each time a player moved and came out of the water to catch some air, the opponent had to take a dive instantly and make their move.

From the pool, Niemann proudly showed his medal to the applause of local supporters, before taking up Diving Chess World Champion Michal Mazurkiewicz next. The Polish player won a rook and pawn for a bishop due to a blunder by Niemann as early as move two, but the American grandmaster managed to outplay his expert opponent after all to win that game as well.
The Diving Chess competition was the first of several side events that are part of the Freestyle Chess Grand Slam Finals. Also on Friday, the other four participants of the Finals visited the University of the Western Cape where they met with about 200 fans of all ages, most of them players from local chess clubs in the Cape Town area for a simultaneous exhibition. This event was organized by Freestyle Chess in partnership with Chess South Africa.

EXPAND YOUR CHESS HORIZONS
Data, plans, practice – the new Opening Report In ChessBase there are always attempts to show the typical plans of an opening variation. In the age of engines, chess is much more concrete than previously thought. But amateurs in particular love openings with clear plans, see the London System. In ChessBase ’26, three functions deal with the display of plans. The new opening report examines which piece moves or pawn advances are significant for each important variation. In the reference search you can now see on the board where the pieces usually go. If you start the new Monte Carlo analysis, the board also shows the most common figure paths.
Among the participants in the simuls were streamers Anna Cramling, Dina Belenkaya, and Niklas Steenfatt. Parham Maghsoodloo (Iran) was present as well and played blitz against many fans for 2.5 hours, taking just 30 seconds on the clock against five minutes for the opponent (and a one-second increment each). He still won all games. Afterward, it was time for selfies and autographs, all in a very cheerful atmosphere.

Earlier in the day, Magnus Carlsen and Jan Henric Buettner gave a press conference at the Silo Hotel. Buettner said he was particularly happy to be in Africa: “I know that the African population, at least the people who follow chess, are extremely happy to have such a tournament here with Magnus and all the other great players. We have eight top players. It’s fantastic, and we’re very grateful and excited to start this tournament.”
Carlsen had been to South Africa and Cape Town once before, during a family trip in 1999, shortly before his 10th birthday. “I’ve always wanted to come back, but it hasn’t panned out, so I’m very happy to finally be back in this beautiful country,” he said. “People keep telling me the city has changed, and what can I say — it’s still beautiful!”
