I'm diving into some serious hyperparameter tuning for my #chess program! ♟️

I'm using Optuna, and seriously, what a great API—it's super easy to use and makes the process so much cleaner. Getting closer to finding that optimal configuration!

Little riddle: "The following code crashes, where is the bug ?"
October 15, 2025 at 10:06 AM
Little bug in vscode python. For those unfamiliar to python `1` is completly different from `1.0`. The former is a int, and the later is float. No big deal, but confusing 😵‍💫

Progress in my #chess engine based on machine learning. Look at those curves! The way the validation follows the training, they feel like that made to go together 😀 #buildInPublic

Level Unlocked! 🔑 Spent the night diving deep into the UCI Protocol (Universal Chess Interface). This is the secret handshake—the standard that lets you chat with any #chess engine via stdin/stdout. Suddenly, building my own engine feels a whole lot more real! Standard achieved. 👑 #buildInPublic

A neural network model on its own cannot produce a reasonable move, as it lacks the depth of calculation required. #chess #buildInPublic

#chess fun, using fishtest pgn files (aka the chess game done by stockfish during testing), i found a "+M77" which means stockfish is evaluating that it will do Mate in 77 moves.... This is depth in the sea of chess 🤪🐳⚓ #buildInPublic

OK tonight im learning the FEN specs #chess #builtInPublic en.wikipedia.org/wiki/Forsyth...

Coding a #chess in pytorch... how come there is no early stopper in pytorch... everybody has to recode its own... #buildInPublic

Raise your hand if you code enough #chess to be able to be able to encode a board in FEN by hand 🙋‍♂️🖖

Fun in #Chess 🎉 #Stockfish is crashing when you send it a position which is illegal (e.g. invalid castling rights)... and i means crashing, not returning an error... Gasp 😜

Progress in my #chess model 🎉, real happy about the result 😀

Note how the training loss is above the validation loss, this is due to a nice balance between the learning rate scheduler and the dropout probability. This means it fight against overfitting efficiently ❤️

More on chess via ML tomorrow!

Tonight i learned Monte Carlo Tree Search (MCTS), a nice way to handle AI, where AI doesn't understand the game it is playing, it just play it randomly... More powerfull that it seems at first 😀

I coded a tictactoe, connect4 and othello in the everning. It is that fast.

Best video to understand how alpha-go use machine learning to become the best #chess computer! 4min tottaly worth it 👍

In #Renaissance culture chess was progressively considered on par with poetry, music, literature and art & therefore an eminently suitable activity for a cultivated family, like the Anguissolas, to be engaged in.

Coding #chess bot with machine learning is a good application. Especially if chess is your hobby.
September 24, 2025 at 2:15 PM
learning that transformer and self attention can be applied to spatial information like chess. Usually they are used for language and time series, and for their ability to model sequences over time. #chess

This ML #chess bot seems very good at the begining of the game... if i keep only the 20 first move, it predicts the same as stockfish 95% of the time... a little too good to be true 😱

Or maybe the bot has just learned all the opening..

When coding a machine learning chess bot, it is possible to paste the PGN of the bot game into chess.com and make it estimate the ELO.

It estimate 1500 ELO but got 5 blunders... the 5 blunders are worry some 😜

September 19, 2025 at 6:28 PM
Look ma, the bot is able to make a few moves! #chess

Ascii visualisation ftw 😜

Starting to code a machine learning chess bot... whish me luck 😀
