♝♞ Play chess against the Stockfish engine in your terminal.

✨ Hey-o 👋

I'm Nick. I like plants, discrete math, chess, programming language theory, playing soccer, going for casual runs (only when it's nice out), taking photos, and spamming my friends with tiktoks.

I currently work at Notion building cool enterprise features.

chs's Issues

Board not straight

I have no idea why but for some reason the board is not straight on my console. ( I am on a linux vm on chromebook).

Custom board size

Would it be possible to customize the board size? On a high-res screen the board looks too small.

Request for a 'save' command

Thank you for making chs !

This is just a quick request for a 'save' command that would allow a game to be saved at its current state, and then continued at some point in the future (possibly from a different machine).

Thanks again,
Nicholas

I have that error when try to run from a raspbian.....
Thanks.

Install error "Could not find version"

After running the install command, I get the following error:

Installation notes for python3.9 / Fedora 33

Ran into some issues with editdistance due to it not having wheels for python >3.7, this is the solution.

sudo dnf install gcc-c++ python3-devel
CFLAGS="-Wno-sign-compare" python3 -m pip install chs

That's all.

---

Details in case it helps anyone searching:

gcc errors make build editdistance python3.8 python3.9 linux

warning: comparison of integer expressions of different signedness: ‘int’ and ‘long unsigned int’ [-Wsign-compare]

Solution: set or export CFLAGS="-Wno-sign-compare"

editdistance/bycython.cpp:24:10: fatal error: Python.h: No such file or directory

Solution: install python3-devel (might be called python-dev or python3-dev on Ubuntu/Debian etc).

Chess pieces do not appear in console tty linux mode.

Hello,
As said in the title and as shown in this screenshot (taken with the fbgrab tool), the chess pieces do not appear in console mode (ctrl+alt+Fx); there are dots instead.
However, it works on the terminal in graphic mode (Gnome Terminal & Kitty).

How I can resolve this ? Thanks in advance.

You cannot promote a pawn?

Is there a command to promote pawn or does it not exist?

Play as black

Hi, wanted to confirm if there is a way currently to play as black instead of the default white. As I'm not able to find any indication of this in the command help or README here. Thanks

Want to output user and stockfish moves to oled

Hi would like to output the moves on the oled for both player and stockfish .Also would like to know how can i extract stockfish moves to communicate to arduino using serial communication for automatic chess without any terminal

FileNotFoundError

When I try to run chs it only comes back with a "Uncaught error "FileNotFoundError", exiting the app.

Readme spelling error

Under how to play "alegraic" should be algebraic.

fuzzy search legal moves

Instead of having the user type out the entire move, generate all the legal moves for the current position and then use the user's input string to fuzzy search against that. This will greatly enhance usability.

custom user flags

objective
the program can simulate =

human vs human
human vs engine
engine vs engine

nice to have custom user flags before run the program, e.g.

chs -w human -b human
chs -w human -b engine --engine_path_b /bin/fruit
chs -w engine --engine_path_w /bin/sjaakii -b human
chs -w engine --engine_path_w /bin/crafty -b engine --engine_path_b /bin/sjeng

support more engines

objective
support more engines both uci, xboard / winboard

already tested in osx by edit
~/Downloads/chs/lib/python*/site-packages/chs/engine/stockfish.py

1. tested engine path that work with popen_uci() and 'Skill level' active :
uci :
brainfish, fairy_stockfish, stockfish, stockfish_mv

2. tested engine path that work with popen_uci() and 'Skill level' inactive / commented :
uci :
asmfish, bikjump, brainfish, cinnamon, combusken, critter, deephiarcs, defenchess, drofa, ethereal, fairy_stockfish, fruit, gfruit, glaurung, hiarcs, komodo, laser, senpai, shredder_classic, smaug, stash, stockfish, stockfish_mv, tiny, toga2, wasp, winter, wyldchess, xiphos

uci_xboard :
cheng, gnuchessu, greko, k2, sjaakii

3. tested engine path that work with popen_xboard() and 'Skill level' inactive / commented :
uci_xboard :
gaviota, greko, sjaakii

xboard :
crafty, sjeng

the engines works can be more than tested above, perhaps due to python-chess module version updated, e.g.
chessdblet, dreamer, fairymax, leonidas, phalanx, polyglot, pulsar, pychess, scidlet

chess figures look weird

I really like the program, but i use powerlevel-10k and the patched nerd font meslo, which is specifically for powerlevel10k, yet my chess figures look weird, do you know why? As Terminal i use guake.

Command 'chs' not found

I am a Linux user. I was installed chs with pip and followed the install instructions. I typed "chs" (without the quotes) into the terminal, as was instructed, but the terminal states that there is no such command. How do I fix this? Can it be fixed?

Blindfold

Is there an option to turn the board off during the game? stokfish played moves should be announced in pgn fromat

Need a new release - FileNotFoundError

Issue #3 was merged, but a new release wasn't made. Therefore, when installing via pip chs will terminate with FileNotFoundError.

Borrowing ideas from EdChess

Just discovered chs a few minutes ago and love what you've done so far!

Back in the day I used to play EdChess on DOS all the time. I haven't found a similar console chess client anywhere else. I wanted to post a link to it here in case it might give you ideas for future directions.

Request for a resign command

I tried to resign using "resign", then "exit", eventually just said screw it, and tried Ctrl+C, which it registered as resignation. Using a more intuitive command such as "resign" would be better (and then maybe "new" to start a new game, rather than running the application again); or if not, at least add the fact that Ctrl+C resigns to the readme.
