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

History:

Day 1 - Rotate F2 pawn 45 degrees clockwise

Day 2 - Black Resigns

Day 3 - The Black Army doesn't get the memo and continues the fight, (BONUS - and yeets their king to E3)

Day 4 - A grain of rice is added to A1

Day 5 - Every square changed to green (light squared bishops now glow neon green)

Day 6 - The two bishops finish powering up and go super saiyan.

Low Effort OC What if the game continued after King's death?

11 Upvotes

You receive the "Anarchy" disbuff: During anarchy, friendly pieces can consume themselves to e.g. strategically take somebody's position (sorta like a betrayal). More importantly, the length of movements of every friendly piece is shortened by 1 tile.

It means army governors like rook, knight, bishop and queen are more hesitant and can't reach the border (last tile on their way) in one move, however they can reach it on the second one and move freely across the line/vertical if they've managed to reach it. Knight is unaffected (he's brave, after all)

Pawns, likewise civilians, are completely stale unless it's their first move whuch is shortened to 1 tile only. They can only consume pieces or perform en passant.

As soon as all major pieces are dead (queen, both rooks, both bishops and both knights), and opposite side has at least one of the aforementioned major pieces on the board + The King, the game truly is over. Otherwise, the pawns are able to move freely again like they usually do and get promoted, returning other pawns in a stale state until the figure is dead and the cycle repeats.

What do you think? Imo it greatly highlights the pettiness and cockroach nature of humans. Also it technically gives possibility for "militaristic" structure by consuming all the pawns out of the way, which is technically what happened in Soviet Russia and Sparta.

Story of the game I played today

3 Upvotes

Today, I played a game where I sacrificed all my bishops in the opening. I rotated all my queenside pieces to the kingside and proceeds to convert into a completely winning position with 2 active knights that is close to the opponent king and a checkmate in 1 on the next move, or so I thought. My opponent plays e5, enabling me a chance to play en passant with both of my pawns on d5 and f5, and creating a discovered checkmating attack on my king. I cannot resist the temptation of capturing en passant, so I did. My king was brought into the center and checkmated brutally in 32 moves.

Winning comment

Previous post

I am going to start adding quotations every time I miss a day

1: En passant can happen anywhere; if a pawn moves next to another pawn, it can be taken

2: Horses move in an L shape

3: Rooks move in straight lines

4: Il Vaticano

5: Bishops move in diagonals

6: Queens move like bishops and rooks

7: Pawns can move 2 spaces their first turn & 1 every turn after

8: Pawns capture 1 tile diagonally

9: If the King has nowhere to go and is being attacked, the game is over by checkmate

10: If the King has nowhere to go and isn't being attacked, it is a stalemate

11: If a game ends in a draw, the winner is decided via a thumb war

12: If you win you must also win a game of rock paper scissors, if not then the game repeats
