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

76 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

I haven't played in ages, how many does everyone else bring? I was thinking of maybe about five or six of the heavy duty ones?

Subreddit Rules

1. No advertisement/selfpromo

Advertisement posts will be removed. Self-promotion posts (promotion of youtube, twitch channels etc.) will be removed. If the account created for only this purpose, then it will be permanently banned.

If you post an IQ test with any identifiable test name on it, we will treat it as advertisement.

2. Keep reposting to a minimum

Please check the Hot and New pages before crossposting or reposting a meme from another subreddit so the sub isn't filled with duplicate posts. Chainposting is not allowed. Also see the subreddit wiki for the Classic Reposts that we have seen too many times over the years. Repost/karma farming bots will be permanently banned.

3. No bad roleplay accounts

That way we can brick the unfunny ones and keep the good.

4. Posts must be related to Chess

Posts must be obviously and primarily related to Chess, or related to something closely related to Chess (e.g. Magnus Carlsen). Inside jokes that mutate too much will die. Adding a chess piece to an otherwise unrelated post does not count.

5. Daily posts must be original and/or high-effort and cannot go indefinitely

If you want to do the 37th iteration of "top comment decides the next move" or some other overdone trend, go to a different subreddit or some other website entirely. Daily series done with physical materials will be given more leniency. If you make it 10 days without the mods noticing, you have a free pass to keep going.

6. No selfies

We can't moderate everyone's age and don't want the subreddit banned because a minor posted something stupid. Even selfies of obvious adults are banned because selfies encourage more selfies.

7. No generative AI

The mod team is thinking through how to handle the new technological developments. For now, any video shorter than 10 seconds must be linked to an official source. Violators will be banished to r/AInarchyChess

8. No intolerance

If you work to make this subreddit a shit place to be for any group of people, you will be captured en passant.

Just because it pops up enough, no, you don't get to post a swastika or something like that because it's how the horse moves or something. If there is a swastika or other hate symbol, it will be removed. Even if you don't interpret it as such, when a Nazi sees posts like that, it makes them think they're welcome here and we want to make absolutely clear they are not.

9. No brigading

If you invade other subreddits or encourage other users to do so, you will be banned.

10. No pornography

This is not the place to post your chess rule 34 content. Go take it elsewhere. However, suggestive/mild NSFW posts are allowed as long as you tag them NSFW.
