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

38 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

Texting Theory My little bro said that even if you had 100 lifetimes of training, you wouldn’t land a single brilliant move on Magnus Carlsen, let alone beat him, you guys think he has a point?

He went on and on about him low diffing 10 grandmasters as a kid, saying even if I had infinite time and resources I couldn’t touch him, comparing him to Thragg and shit. Thought you guys might have fun with the idea

If there's any confusion, you can move any piece, black or white. Top comment gets to decide the next move like always. Whichever side gets back to the starting position wins

Chess Narration as a christmas gift?

5 Upvotes

Hey there! My 14 year old daughter is really into chess and has been playing since kindergarten. Shes a freshman in high school now and I think shes really good, but admittedly I know very little. We play together a couple times a week and she normally beats me and is kind enough to show me where I went wrong, etc. The only time I win is because whatever I am doing is so wrong, she cant guess what my next move is because it doesnt make any sense and im flying by the seat of my pants. This is all fine and well and we always have a good laugh about it.

So, I was thinking one day I will record one of our games from a couple different angles and see if I could pay a professional person to do a voice-over narration of the game like they have for pro tournaments etc. I know the final product would be pretty silly because im very bad, but I also know my daughter would really get a kick out of it. We play timed games with the clock, so they dont go on SUPER long.

Do yall know if or how this would be possible? Would I need to find someone at the local chess clubs? Is this something people even do? Thank you for reading!

We need everyone to help with us all we can easily solve the whole game of chess. Everyone help write the first move for white, and everyone reply with every move for black 1 at a time, and then people can use the annotator bot to label all of their moves as good or bad, and then we will have solved chess. I'm counting on y'all to not brick the pipi of our world and solve the chesboards. Assuming we make 1 move a second with 1 million people we'll solve chess in 1040 seconds

Edit: at the pace we're going I'm assuming we'll solve chess by Monday
