Mark Crowther (Sat May 02 16:08:59 2026)

Magnus Carlsen played a risky Benoni as black against Nils Grandelius and scored an impressive win. Abdusattorov had numerous chances against Woodward, Van Foreest was winning for a long time against Zhu Jiner and Erdogmus against Erigaisi saw both players with chances but these games all finished in draws.

Rameshbabu Vaishali won the FIDE Women's Candidates tournament after beating Kateryna Lagno in the final round. Praggnanandhaa's elder sister will play Ju Wenjun for the title later in the year. Sindarov forced a quick draw in the final round to finish on +6 undefeated. Giri finished second after beating Bluebaum, Caruana finished 3rd after beating Esipenko. Strange statistic, there were no Ruy Lopez variations played in the open section.

FIDE Candidates Tournaments 2026

FIDE Candidates Tournament 2026 Games and Results

Mark Crowther (Sun Mar 29 00:12:00 2026)

The FIDE Candidates Tournaments both open and women's events take place in the Cap St Georges resort, Cyprus, Sun 29th Mar to Thu 16th Apr 2026. I would argue that this is the highlight of the entire FIDE World Championship cycle. The poor form of the current champion Gukesh has to be a major motivating factor for anyone in the open event. The event is on the periphery of the current Iran conflict and Humpy Koneru decided that she would not participate in the women's event due to the perceived danger and was at the last minute replaced by Anna Muzychuk.

Players open: Hikaru Nakamura, Fabiano Caruana, Anish Giri, R Praggnanandhaa, Javokhir Sindarov, Andrey Esipenko, Matthias Bluebaum and Wei Yi.

Players: women: Tan Zhongyi, Anna Muzychuk, Bibisara Assaubayeva, Aleksandra Goryachkina, Kateryna Lagno, Deshmukh Divya, Rameshbabu Vaishali and Zhu Jiner.
