Congratulations to 🇺🇿 Javokhir Sindarov for winning the FIDE World Cup in the tie breaks against 🇨🇳 Wei Yi. There is no way I would have predicted these two being in the final beforehand. Here's a link to the final game of the match […]

What should parents know about AI toys? I chatted to @rebeccaruiz.bsky.social about how little evidence there is on their impact and children's relationships with them. Read the @mashable.com article here: mashable.com/article/ai-t...

Kramnik needs to be sanctioned. FIDE is too gutless to do it. #chess https://www.bbc.co.uk/news/articles/crmxj102039o

Rest in peace Daniel Naroditsky. I always enjoyed spectating you in the Lichess titled arenas. You are a chess legend!

I’ve joked before that it would be wise to declare it against my religion to view advertisements. But the more I think about it, the more I see the advantages of this idea. When something is framed as a matter of religious conviction, people tend not to question it — they might even go out of […]

Some cool news about #apple taking memory vulnerabilities seriously: https://security.apple.com/blog/memory-integrity-enforcement/ My understanding is that it improves upon the probabilistic protection of the original #mte to make the probability of a successful attack even lower. I'm a little […]

After playing #LumoAI by #Proton in #chess, I decided to try #o4mini by #OpenAI. The result was fairly similar. Very strong opening followed by inexplicably dropping its knight and queen in the middle game. At one point it even argued back after I told it one […] [Original post on fosstodon.org]

Very cool game by Levon Aronian beating Sam Shanklamd in round 7 of the St Louis Rapid and Blitz https://lichess.org/broadcast/gct-saint-louis-rapid--blitz-2025/rapid-7/DRhDQy1R/rAucOcHB #chess #lichess #stlouis #grandchesstour

A great photo of the World Cup winner Divya Deshmukh. Such an amazing achievement, and a classy way to earn the GM title! #chess #FIDE #batumi #india

I played #chess against #LumoAI from #Proton. I had to correct if a few times when it was trying to make illegal moves but it wasn't too tedious. It was quite good in the opening from my point of view but didn't really have any middle game plan. It's definitely […] [Original post on fosstodon.org]

Divya missed a crucial opportunity in the world cup final against Humpy. Can you see the alternative move? The second game starts in about an hour. https://lichess.org/broadcast/fide-womens-world-cup-2025--finals/game-1/fARMvz3I/Z5AoPwhJ #chess #fidewomensworldcup

Final of the chess world cup is about to start between two stars from India: Koneru Humpy and Divya Deshmukh. It's a clash of generations! https://lichess.org/broadcast/fide-womens-world-cup-2025--finals/game-1/fARMvz3I #chess #FIDE #india

Levon Aronian is playing the tournament of his life in Freestyle #chess. He beat Magnus Carlsen, Arjun Erigaisi and Hikaru Nakamura.

I recently came across this old chess puzzle again. You need to place 8 queens on the board such that none of them attack each other. I'll put two solutions I've found in the comments.

Anish Giri :netherlands: wins the Sharjah Masters 2025 with a +5 score. Amazing! https://lichess.org/broadcast/sharjah-masters-2025--group-a/round-9/oRqH8iDR#players/24116068 #chess #lichess #anishgiri

朱锦尔 (Zhu Jiner) wins the FIDE Grand Prix and a spot in the Women's Candidates tournament 2026. https://en.wikipedia.org/wiki/FIDE_Women%27s_Grand_Prix_2024%E2%80%9325 #chess #FIDE #zhujiner #candidatestournament #grandprix

Magnus Carlsen scores a perfect 9/9 at the Grenke Freestyle chess open. An amazing achievement akin to Bobby Fisher scoring 11/11 in the 1963/64 US Chess Championship: https://en.wikipedia.org/wiki/US_Chess_Championship?wprov=sfla1 #MagnusCarlsen #chess #freestylechess #chess960 #wikipedia […]

Such a great performance by 居文君 (Ju Wenjun) winning her fifth world chess championship match! #chess #FIDE #worldchesschampionship #jutan

Ju Wenjun is a draw away from retaining her world championship while Magnus Carlsen wins the final of the Feestyle chess grand slam in Paris. What a day in chess! Follow all the action on Lichess […]

Magnus Carlsen beat Hikaru Nakamura to pull ahead in the final of the Freestyle chess grand slam in Paris. Here was the starting position: https://lichess.org/analysis/chess960?position=103 #chess #freestylechess #chess960 #lichess

Fan favourites Hikaru Nakamura and Magnus Carlsen are through to the final in the Freestyle chess grand slam in Paris. Vincent Keymer and Fabiano Caruana will now need to face off for the third place. #chess #freestylechess #chess960

居文君 (Ju Wenjun) defeated 谭中怡 (Tan Zhongyi) for the second game in a row taking a 2 point lead in the match and in a great position to defend her world chess championship title! We need to wait two more days while the match moves to 重庆 (Chongqing). #chess #jutan #FIDE #worldchesschampionship

Tomorrow Hikaru Nakamura plays Vincent Keymer and Magnus Carlsen plays Fabiano Caruana in the semi finals of Freestyle chess Paris grand slam. Vincent Keymer won a thrilling tiebreaker against Ian Nepomniachtchi. https://chess-results.com/tnr1127213.aspx #chess #freestylechess #chess960

Ju Wenjun strikes back against Tan Zhongyi in the world chess championship. What a start to this match! See the whole game on Lichess: https://lichess.org/broadcast/fide-womens-world-chess-championship-2025/shanghai--game-3/tiGkcqB6/40nNyfSM #chess #worldchesschampionship #jutan

Tan Zhongyi beat Ju Wenjun in their second game taking a big step in regaining her world chess championship title! #chess #worldchesschampionship #jutan

The first game between Tan Zhongyi and Ju Wenjun in the world chess championship ended peacefully in a draw. It was a very balanced game with neither player taking too much risk: https://lichess.org/broadcast/fide-womens-world-chess-championship-2025/shanghai--game-1/Ao99TiHo/HoGQDZD2 #chess […]

After defeating the world numer 1 Magnus Carlsen in the semifinals, Vincent Keymer now took the lead in the final against world number 2 Fabiano Caruana. Amazing performance by the 20 year old in the Freestyle chess grand slam! #chess #chess960 #freestylechess #MagnusCarlsen #FabianoCaruana […]

Gukesh and Praggnanandha lead going into the final day of the Wijk aan Zee chess tournament. It's surprising not to see Giri or Caruana near the top. #chess #wijkaanzee #TataSteelChess

Just over halfway done with the Wijk aan Zee tournament. Here's a graph of how things have progressed so far. It's a three way tie at the top. #chess #matplotlib #wijkaanzee #TataSteelChess

The #FIDE drama continues as it threatens to sanction players who play in the #freestylechess tour. This fighting is not good for #chess.

Amazing game between the new world champion Gukesh D and Dutch number one Anish Giri in round 1 of Wijk aan Zee. ChessNetwork analyses the game here: https://lichess.org/@/Chess-Network/blog/gukesh-d-vs-anish-giri--tata-steel-chess-2025/drEJpqTT #chess #wijkaanzee #TataSteelChess

Chess World Rapid and Blitz championship has started with the conclusion of round 1. https://lichess.org/broadcast/fide-world-rapid--blitz-championships-2024--rapid-open/round-1/kTmtGlGP https://lichess.org/broadcast/fide-world-rapid--blitz-championships-2024--rapid-women/round-1/u6hu5ZZ7 […]

So much chess to watch between Christmas and new year as the FIDE World Rapid and Blitz kicks off. Do you like the new knock out format for Blitz? #chess #FIDE #rapidblitz

Gukesh D as world chess champion! It's been a very exciting match to follow. #dinggukesh #chess #FIDE #worldchesschampionship

Looks like Ding is sacrificing a pawn. It doesn't look like he's running much risk here. #dinggukesh #chess #lichess

The final classical game of the world chess championship is off. I'm excited to see 1. Nf3! #dinggukesh #chess #lichess

I just found out the Guardian has been covering the World Chess Championship: https://www.theguardian.com/sport/2024/dec/11/chess-world-championship-gukesh-ding-game-13-updates What's your favorite news outlet for coverage? #dinggukesh #theguardian #chess

It feels like Ding has escaped a difficult position today. This was a big chance for Gukesh to take the lead and probably the title. #dinggukesh #chess

I've been following the official FIDE stream for the world chess championship, and I'm so excited for the next two games! #dinggukesh #FIDE #chess

OMG D!NG! #dinggukesh #chess
