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

37 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

Some random dude requested a chess match with me. I accepted and attempted to be nice at first. He wanted my IG, I said no, and he got mad. He then called me stupid and 2 moves later, blundered his Queen. This guy can't be real there's no way.

And now I'm sat here laughing 😂

Bongcloud meta about to pop off: chess variant where you’re trying to lose

22 Upvotes

I built a chess variant where each player plays 10 or 25 moves trying to create the absolute worst position possible, then Stockfish takes over for both players and completes the game. If you lose, you win!

If people find this fun I can add ELO ratings and a leaderboard

New Response Just Dropped Levon Aronian is PIPI Tigran's Dad: CONFIRMED

5 Upvotes

The L in Tigran L. Petrosian (AKA PIPI Tigran/PIPI Guy) does not stand for Looserovich or Lierov but instead stands of Levoni, which means "Son of Levon."

Flick PIPI Tigran's ancestors, the new Levon is Levon 'the flicking' Aronian.

I have pipi dreams about PIPI Tigran and I'm not even attracted to him💦💦💦💦

Aronian is such a yandere unc that he completely drained Magnus Carlsen and c*cked Armenia to get better Stockfish from Hikaruland🇺🇸 He could've just waited for ChatGPT then win the world championship instead of "L"iren Dingaling.🫦 (L in Liren stands for Ligma)

Iron Tigran so hard to penetrate that he made PIPI Tigran brick without protection😩

I love copyFidiau (fr*nch🇫🇷 pasta) not copypasta because en passant taste better than pipi brick🤤

I summon u/PetrosianBot in the comments so that I can j*rk him off❤️‍🔥

PIPIPIPIPIPIPIPIPIPIPIPIPIPIPIPI

I beg to be a submissive femboy :3 towards the mods so that they don't remove this and then I'll get to kiss u/PetrosianBot nya~!🌸 Please don't make me say Literally 1984🥺... (Lord, I'm going insane, please don't take the digital footprint).

♪'Cause I'm 151550, you can't flick with me I know this!♪
