  • ♟️ Bringing Chess to Life in Your Browser — Powered by Stockfish and Sass
    As a FIDE-rated 2100+ player and a developer, I’ve always been fascinated by the blend of chess precision and tech creativity. That’s what inspired me to build BlunderBot — an online chess-playing AI that runs right in your browser, powered by Stockfish and built with modern full-stack tools. - Source: dev.to / about 1 year ago
  • OpenAI o3-mini Tested in LLM Chess
    If we compare the performance of LLMs to a popular Stockfish chess engine (playing as black against the same random player), Stockfish scores 100% wins with an average game duration of 58 moves. That's at Skill Level 1 (out of 20) - supposedly the level of a beginner human chess player. Compare that to the current best of o1-preview-2024-09-12 with a 47% win rate at 125 moves average game duration. I have touched... - Source: dev.to / over 1 year ago
  • which of these would you rather attempt for $1million?
    Play a bit against the Chess Engine https://stockfishchess.org/ if you want to get an idea about what an elite chess player can do. Source: about 3 years ago
  • The Q&A Megathread for new and beginner chess players
    So if you want to play against Stockfish, play against it. And in fact I would recommend not playing it on chess.com or Lichess with their artificial crippling levels. Download Stockfish, put it on a GUI and play it full strength and have fun getting utterly demolished. Source: over 3 years ago
  • Is ChessBase really that necessary?
    For us mortals I suggest SCIDvsPC https://scidvspc.sourceforge.net/ and CaissaBase http://caissabase.co.uk/ (4.8million games) then add Stockfish https://stockfishchess.org/ for analysis. Source: over 3 years ago
  • Any good chess programs
    Just to analyze positions in general, you can use the analysis boards on websites, and I'd recommend also having an offline chess GUI running Stockfish. You can sometimes go deeper and fiddle with more things. My recommendations are Scid vs. PC or PyChess. You would need to download Stockfish too, as the built-in ones are a bit oudated.

  • Need help with chess project
    Hey, thanks for the mention! Unfortunately I am writing the code for my board, but from all the comments I've received, it seems like Stockfish may be a helpful resource. Source: over 3 years ago
  • CC analysis says 83% accuracy, Lichess says 93% - why the difference?
    The Accuracy metric indicates how well you play - according to Stockfish, the strongest chess engine. Source: over 3 years ago
  • What AI is currently the best at chess?
    The best engine as of today is Stockfish 15.1 which would comfortably beat AlphaZero which played in those matches. Source: over 3 years ago
  • What do you guys think is the best method for making a computer analyse a position?
    I'd recommend a chess engine like Stockfish (which you can download for free from http://stockfishchess.org/). Source: over 3 years ago
  • What’s the word I’m looking for?

  • Generating Chess Puzzles with Genetic Algorithms
    How can we know that there’s exactly one good move? We can use the open source chess engine Stockfish. Our python-chess library actually has support for communicating with an engine like Stockfish. That means that getting a detailed analysis of a position is as simple as:. - Source: dev.to / almost 4 years ago
  • Teen Grandmaster Hans Niemann "likely cheated" claims top Chess site
    I looked through those and unfortunately none of the main comments I saw were about Stockfish which is a well-known, open-source chess engine. It is very commonly used by online chess commenters. Source: almost 4 years ago
  • What is the highest form of intelligence?
    No wonder why no human can't beat it and also most of the traditional chess engines like: Stockfish, Leela. Source: about 4 years ago
  • Hikaru reveals Hans cheated in the past
    Sounds like you are familiar with cheating in FPS games. However chess being a different kind of game means nobody pays anyone to make an engine, because the [strongest](https://stockfishchess.org/) [engines](https://lczero.org/) are completely free and open source. Source: about 4 years ago

    And that's it, apart from developing your groundbreaking RBC algorithm, of course! Consider modifying the TroutBot code (which requires StockFish) as a first step. Source: about 4 years ago
  • 4 year old can semi-functionally play chess, now what?
    I taught my son right around his 4th birthday. We played a little and he was just like your son - really just moving pieces because he can, not because it's a good idea. But he went and downloaded Stockfish 15 (https://stockfishchess.org/), and played with it regularly. Fast forward 2 years and he comes and says "daddy can we play chess?" Sure. We start to play and he's playing with purpose - thinking about why... Source: about 4 years ago
  • A lot of high quality games are going on at Candidates. This is not one of them but i forced Stockfish to take En passant.
    A GM level player with lots of ELOs. Plays lots of games. Doesn't really do much beyond play Chess. They say he or she plays for free. People have a fanclub or something over at https://stockfishchess.org/ and rumor has it Mr/Mrs Stockfish will make an appearance in court in somewhere that sounds french. Source: about 4 years ago
  • stockfish lvl 8 (the highest on lichess) just played the Halloween gambit against me? Why on earth would it do this?
    The web versions use a weaker net when compared to the full application. Source: over 4 years ago
  • chess game made with pygame
    Well, creating a chess AI all by myself is a feat I wouldn't be able to accomplish -maybe yet-. So I used a pre-made engine called Stockfish, which I am pretty sure that you are familiar with. I then used a module named after the engine itself that integrates the engine with python and provides a very abstract model to work with. In short, no; I did not write a chess AI from scratch. I would love to do so in the... Source: over 4 years ago
