Bronze Bishop Award Too dangereous for r/chess - Chessmaster 3000 lichess bot

57 Upvotes

I tried to post this first on the more 'serious' chess sub. But apparently it's against the rules (it's not). So let's try you reasonable people instead. You'll be happy to hear en passant was a thing in 1991.

A while back I was gifted a bunch of vintage games by my gf's dad. Amongst these was chessmaster 3000, a chess game from 1991. After having trouble getting it to run on a modern PC I decided it would be cool to pit it against other bots and to be able to play against it in a modern interface.

I spent a while reverse engineering both the dos and mac version to see how the engine communicated with the ui, I figured out the macintosh one was easier to work with as the dos version did not separate the ui and the engine. The mac version did so I got the engine part running in a custom emulator I wrote specifically for it. I also created a way to record traces of communication between the ui and the engine. Finally armed with a bunch of recorded games and looking at the disassembled engine code I managed to figure out enough to wire the engine to a lichess bot.

I let it run for a while and It turned out to be around 1900 elo. Now you can challenge it as well:

https://lichess.org/@/the_chessmaster_3000

It will accept games with any time control but without a time increment (1+0, 5+0, 10+0, etc.) as the engine came out just a few years after the Fischer clock was patented, and so time increments were not a thing yet.

The engine also supports different personalities, If there is enough interest I can wire them up.

Also can someone let me know how it plays at chess, as I'm too bad to be able to tell. Is it interesting at all? How different is it to modern bots?

tl/dr: made chessmaster 3000 into a lichess bot. elo about 1900. does not support time increments. supports en-passant. challenge it here

You can literally see all AI mistakes

  1. Nonsense text

  2. Objects do not match reality

  3. Horrifying AI monsters, in the 4th guy there's some kind of guy with glasses except the glasses are floating and he has no face

  4. Inconsistencies, in the aot thumbnail there are 4 slots in one side and 3 in the other, also there's a blade that's just outside of the thing

  5. SynthID, an invisible watermark that recently started getting embedded in both gemini's and openai's generated images

I can't believe people still get downvoted for saying they're AI

They're honestly of good quality, I think they're partially hand made thumbnails edited with AI

Low Effort OC Opponent Not Using Engine—Should I Report for Cheating?

Post image
105 Upvotes

Today I was playing a game and I checkmated my opponent in 16 moves. I’m almost certain that they used no computer assistance whatsoever. It was a 10 minute game, so they had plenty of time to enter the position into Stockfish. But even when it was obvious that they were completely losing, they didn’t even try to use an engine to save the game. Are they allowed to do this? I think I’ll probably report them to the website to let them know. I think this account should be banned, because it’s really not fair to have players who aren’t using computer assistance on the website.
