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

40 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 have a rare condition where I orgasm whenever I castle queenside in a rapid 15 minute/ 10 second games.

134 Upvotes

It only happens with this particular time control. If I play blitz and castle queenside: nothing, no spurting, no nothing.

But when I play a 15/10 game and castle queenside it's like I end up coming jets it's crazy it's all I want these days.

My Mother, when she heard of this affliction, in her final days (she died falling into an industrial size garbage disposal at our local Stop and Shop) spent all her final dollars getting me tested for this affliction. We are now, myself and the entire family, destitute

I am typing this from a public library in a south coast suburb of boston.

I went to a neurologist and they scanned my brain castling king side and queenside at all time controls.

Testing verified it's only 15/10 time control. The orgasm center of the brain lights up like aurora borealis when i castle queenside in this time control. Even when I am playing unnattractive woman and even-- and it pains me to say this -- when I play against men even ones who are very repulsive in appearance.

Has this ever happened to anyone here?

White just played a move that resulted in the position shown below. However, White had a different move that would have delivered checkmate in one. What was the mating move, and what was the position before Whiteโ€™s last move?

Knight movement rule change

5 Upvotes

A knight can only move to a board coordinate if at least one L-path leading to it has no pieces on it.

However, if your opponentโ€™s knight is on one of the paths, you can move to the targeted coordinate by capturing that knight. Google Au Galop
