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.

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.

Kramnik needs to be sanctioned.

FIDE is too gutless to do it.

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 […]

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 […]

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 […]

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.
