Looking at the number of wins compared to the games where each player stood better is really interesting for the women’s candidates.
Vaishali had the fewest games where she stood better, but she converted all these games into wins, which lead to the joint most wins in the tournament.

One amazing thing about Sindarov’s Candidates run is his clock usage. He gets a big lead on the clock from moves 13-17 and then (on average) has 20 minutes more than his opponents until move 40, while no other player has a lead on the clock compared to their opponents after move 20 #chess

How Can Sindarov Be Caught at the Candidates? Looking at different simulations of the Candidates tournament after round 10

Sindarov has a big lead in the Candidates, but how can someone catch up to him?

Sindarov and Caruana won in the 5th round of the candidates, but Sindarov is now the favourite according to my model, as his win with black against Nakamura was less likely than Caruana’s white win against Blübaum.

The women‘s candidates is wide open, with Muzychuk und Assaubayeva leading with +1, but the pre-tournament faviourite Zhu Jiner has the best winning odds, according to my model, despite being half a point behind

Here is how the winning chances for each player have developed over the course of the first 3 rounds in the Candidates.

This is a fun study by H. Holm, 1958. White to play and win

I've looked at how the 6th move for white in the Najdorf has changed over the years. It's really interesting to see how different trends emerged over time
I've also looked at positions leading up to the Najdorf in my post: chessenginelab.substack.com/p/najdorf-st...

Are there any stats about the Candidates you’d be interested in?

I’ll take a look back at the previous editions of the tournament and will also review the upcoming event in the next two weeks

The penultimate round of the Prague masters changed the prediction quite a bit, with Abdusattorov winning his game and taking the tournament lead as van Foreest lost. Now Abdusattorov is given a 60% chance to win the tournament

Van Foreest, Abdusattorov and Navara drew their last 2 games in the Prague masters, but my model gives van Foreest now much better winning chances, as he held draw today against Abdusattorov, who is half a point behind him in the standings

I ran my tournament prediction on the Prague masters, and it’s interesting to see how the winning chances change after each round

I enjoyed this puzzle, black to play and win

As usual, I made a visual recap of the Wijk aan Zee tournament, this time I also included some opening statistics from the event: chessenginelab.substack.com/p/wijk-2026

For a new project, I looked at the score of 2700 players against various other ratings over the last 10 years with both colours.

I also show the score which is predicted by the Elo formula and it’s interesting to see how big the impact of the colour is

My league game today ended up being a quick win, after my opponent made some dubious decisions in the opening. It still feels good to win such a clean game

In my latest post, I looked at the relative number of forcing moves for different players. As one would expect, more attacking players generally play more forcing moves.

While many top players already got eliminated in the world cup, there were fewer upsets in this year’s thirst three rounds compared to the previous two world cups

I had my first league game of the season. It was a very complicated game and I certainly made some mistakes along the way, but I'm happy that I kept it together in time trouble and I managed to win #chesspunks

An Improved Piece Activity Score A new and more refined attempt to quantify the activity of pieces in a position

After a busy summer, I finally managed to publish another blog post, where I worked on an improvement of my piece activity score. Check it out here: chessenginelab.substack.com/p/piece-acti...

Yes, Bg3 even wins the knight by force as White will have to play Ng1 to block the eventual rook check and then Black can play Rf1 and Bf2 and take on g1
