There are a number of open source Chess programs written in Go on Github.

 

Rather than spend a lot of time trying to write my own (likely mediocre) program, I thought I'd simply post a link to [https://github.com/notnil/chess notnil/chess] which explains its various capabilities quite well. However, you need to look at the code itself to see that it can cope with all types of move including castling, ''en passant'' capture and promotion to a piece of the player's choice.

=={{header|Perl}}==

Primarily written to see if I could find all moves with one regex. The answer was "mostly", the main problem being

some moves require history (the current state of the board is not sufficient for castling and en passant).

I also wanted to try different methods of making moves. It does not play well, but then neither do I.

Version 0.8.1+ contains demo\rosetta\chess.exw, a slightly cleaned-up copy of a 20-year old translation of TSCP.<br>

It isn't particularly good (though perhaps a reasonable starting point for something better), at over 1,600 lines it does not really bear any useful comparison to the lisp version, and is simply not worth posting on this site, especially in light of potential copyright issues.

The default Unicode board may look wonky and misaligned with certain terminal fonts. To use an ASCII board instead (like in the output shown below), set UNICODE = False. If your terminal uses dark mode, set DARKMODE = True.

 

The computer may say some things that allude to the chess game in ''2001: A Space Odyssey'', by the way.

# Computer plays Black

 

from collections import Counter

 

UNICODE = True # Print board with Unicode symbols?

DARKMODE = False # Invert symbol colors?

 

board = chess.Board()

for yourmove in board.legal_moves:

board.push(yourmove)

v = Counter(board.fen().split()[0])

p = (9 * (v['q']-v['Q']) + 5 * (v['r']-v['R']) + 3 * (v['b']-v['B'])

+ 3 * (v['n']-v['N']) + v['p'] - v['P'])

p += mobility / 1000

#print(mymove, yourmove, p)

 

print(f"Game finished, result is {board.result()}")
