It's been a year since we added streaks to Chessbook. There are 12 people that have never missed a day since then, with streaks of 365 days! We also have 230 users that have a streak of over 6 months 🔥. Cool to see the dedication. Must be a nightmare to prep against these guys!

Soft-fails and refutations ❓. A lot of people have asked for soft-fails. My thought was that soft-fails should just be fails – even if it's an objectively fine move, you're still exiting your repertoire, which you should aim to stay in. But Ollie had a great insight here: what

Massive local-Stockfish upgrade 🤖. Our local Stockfish, which runs on the browser, has historically been very weak. It's been very limited on memory, single-threaded, and didn't use the neural network (NNUE). Because of that, the number of nodes we evaluate for model games has

If Magnus studied his openings more on Chessbook, he wouldn't have had to split the title 👀.

Chessbook has new ways to review! When you are reviewing your due moves, you can:. - Skip the moves in-between.- Play the moves in-between once per review session.- Play all moves every time. This gives a lot more flexibility. I like the "once per practice", personally!

Why don't chess streams use the Win-Draw-Loss output on their eval bars? Maybe because people would tune out on all the drawn positions 😅. Stockfish w/ WDL says Ding has a small chance, but most likely outcomes are a Gukesh win (40%), or a draw (45%)

Until now, Chessbook has required your repertoires to cover all lines that you can expect at your level. But sometimes you just want a Sicilian repertoire, for example. You can now exclude moves, and Chessbook will stop asking you to fill them in!

How good is your repertoire? You can now tell! Chessbook will show you how your repertoire compares to people at your rating range. Our users have much better repertoires than their peers, averaging 1.5 standard deviations higher on both of these measures!

What about for Black? Obviously no opening is going to have a 60% win-rate there, but the Sicilian shows why it's also the most popular of the tournament, where Black actually has a much higher win-rate than White! 4/

What about the most effective openings? The Ruy Lopez is the clear winner here for White, with a ridiculous 60% win-rate. 3/

It's clear that the Sicilian is the favorite opening of the CrunchLabs Masters. With almost 50% more games than the second most popular opening. The top openings of the tournament are all the usual suspects, but what about the rare openings? And which ones have performed best?
