  Imagine this from the computers POV. They could literally play this game in milliseconds, and the human took over an hour just to move the pieces...

  Mephisto is so powerful that he realized he was playing against a better AI and then tried to play the only moves that allowed him to find a bug in his opponent, maximizing the result considering his computing power.<br><br>An engineering and economic masterpiece in terms of resources/performance.

  Stockfish sadistically dodging the threefold repetition draw a thousand times, then drawing without realizing feels kinda good

  Software engineer here: I obviously don&apos;t have access to the software being used by the chess website, and I also haven&apos;t looked at any of the Stockfish source code, but here&apos;s my hypothesis based on 20 years of experience in the industry:<br><br>This appears to be a discrepancy between the &quot;rules engine&quot; software, which is responsible for enforcing the rules of the game when a player attempts to make a move, and the &quot;game engine&quot; software, which is responsible for calculating the best moves for a given position. The discrepancy is regarding whether or not the game is in a drawn state. As you can see, the rules engine (correctly) believes the game to be drawn: it is preventing any additional moves in the game and awarding each player 1/2 point, effectively ending gameplay. However, if you look at the Stockfish calculation in the final position, the game engine clearly does not believe this game to be drawn: if it did, it would display an equal positional evaluation of 0.00, indicating a drawn position. Instead, the game engine is reporting a 6.23 point advantage for black. This seemingly indicates that, according to the game engine, a draw has not been reached.<br><br>Now, I went back through the video and counted the number of times the final position was reached: I did count 3. This tells me that there&apos;s either a bug in the Stockfish algorithm with respect to recognizing threefold repetition, or a bug in the way the website is utilizing the results of the Stockfish calculations. Given that you have tested this on two separate and independent platforms, I would conclude the former. Exactly what the root cause of the bug is, I can&apos;t say... but the developers contributing to the Stockfish project can figure it out. You should submit a bug report to them via their GitHub page containing the pgn of this game and a link to your video. In my <i>professional</i> opinion, this game is peculiar enough to warrant some investigation on their part.<br><br>As always, great content from this channel. Thanks for all you do for us.

  Legit speechless by this. Can’t be explained as anything other than a bug in Stockfish, and one that I’ve never encountered before. I’ve seen Stockfish unable to determine the strength of a move before it’s played, but missing a one move draw is inexplicable. <br><br>This is such a cool video because of that. You’ll probably never be able to replicate this in a different setting. I’d love to hear some follow up explanation if you find someone who can look under the hood and tell us more. <br><br>Also, great job Mephisto! Lol

  I wish the chess pieces were magnetic so when you moved them they would magnetically stick. Would be so cool.
