lichess-bot's Issues

Auto abort game if white doesn't make first move

I've noticed an issue locking up the bot where users do not make the first move and the bot will wait indefinatly for the move.
There should be an option auto_abort_time: <seconds> (default: 30) where if white doesnt make the first move in x seconds the bot will abort the game, allowing for other games to be played.

This was brought to my attention on reddit: https://www.reddit.com/r/chess/comments/8e3m52/you_can_now_play_leela_chess_zero_on_lichesscom/dxsrdrf/?context=3

LeelaZero starts playing slow at the end

https://lichess.org/EtBqtAug/white
It got a winning position, but then started to play slow and lost on time, although it had 2 seconds left, and could make about 20-25 moves with it's usual speed.

Support for Variants

Set UCI option "UCI_Variant" to key obtained from "variant" field of "Game info" when setting up the engine. So the engine can automatically switch to the correct variant when a game starts.

auto-abort

using the existing li.abort(game.id), when the opponent fails to play their first move in 20 seconds.

Why not use conda package manager ( Miniconda )?

This is really not an issue for me, because I can install the thing for myself, but I watch the readme getting more and more complicated about creating an environment and I see all the user complaints.

Would it not be easier to just require the user to install conda package manager ( Miniconda )?

https://conda.io/miniconda.html

Creating an environment is sort of trivial in conda. Conda has an own console and you can create and activate the env there, but in my experience the environment you create with conda then can be used by simply cd-ing in it in a simple console as well.

Bot stalls when opponent offers draw

See:

https://lichess.org/A3aYRGi7
https://lichess.org/5PhGQKAV
https://lichess.org/yQ8yLEmU/black
...

Playing speed

For some reason the bot is playing very slowly, and always loses on time (by a big margin) taking way too much time even for obvious moves. What could be the cause? Does it have something to do with the option "Threads" and "hash"? Also, it's not clear to me what should I put on those fields.

Make abort_time a Config option

abort_time should be a config option to allow people to make it longer or shorter if they so desire.

ERROR:backoff:Backing off api_post(...)

Hello,

Thanks for a great initiative on bridge between lichess and engines. This is really great!

I am running the bot on Windows using python3 and normally it works well. Sometimes, however, when bot accepts games the lichess-bot fails with the following error:

Accept UltraBullet challenge from Stockfish9-FullPower
ERROR:backoff:Backing off api_post(...) for 0.8s (requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://lichess.org/challenge/4rwLnEPj/accept) ERROR:backoff:Backing off api_post(...) for 1.0s (requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://lichess.org/challenge/4rwLnEPj/accept) ERROR:backoff:Backing off api_post(...) for 2.2s (requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://lichess.org/challenge/4rwLnEPj/accept) ERROR:backoff:Backing off api_post(...) for 1.8s (requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://lichess.org/challenge/4rwLnEPj/accept) ERROR:backoff:Backing off api_post(...) for 13.7s (requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://lichess.org/challenge/4rwLnEPj/accept) ERROR:backoff:Giving up api_post(...) after 6 tries (requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://lichess.org/challenge/4rwLnEPj/accept)

Then it fails. The problems seems to be sporadic, it does not happen every time. I wonder if there are any fixes for this that address the problem?

Thanks in advance,
with best regards, Volodymyr.

Create seek

It would be a great enhancement having a new seek section in config.yml with some user defined seek lines. Using this if a BOT has a free process (and challenges queue is empty) pychess-bot automatically send a new seek (picking the next one from config.yml seek section) to be appear on lichess lobby tab.

Engine never makes the first move when it is black

Is this a lichess-bot bug or something else?

Auto aborting BOT games

Many spectators looking at https://lichess.org/@/LeelaChess/tv LeelaChess vs TiagoRibeiro3 1+0 rated bullet game right now. BOT played 1. e4 but the human opponent seems to not responding at all and he was disconnected.

BOT games should be aborted if opponent is not responding in given time after BOT first move was taken. Similar to human-human games.

Lags

The current master version seems to introduce a lot of lag.
My engine return best move in less than 300ms but clock on lichess side is running for 2 secondes.

It seems there is nothing wrong in my internet connection becaus eif I play game by myself, their is no lag, so probably something inside lichess-bot ?

Do not play aborted games

EDIT: Sorry, I didn't check if a6bbfd7 is to blame. I'll check that later today...

If a game is aborted before the opponent moves, don't spawn dozens of engines (but move on to the next game).

Currently the following is logged (Python3):

Hi, I'm trying to set up stockfish9. I followed all the steps mentioned here, but when the game is about to start, I get this error message:
https://pastebin.com/w78Dw9mi
Do you know why is this happening?
Thanks in advance.

Multiple Errors

Have followed the step by step exactly, only replaced the token and engine in the config.yml and this is the error I get while running python main.py (I'm trying to run leelachess)
"could not find expected ':'", self.get_mark()) yaml.scanner.ScannerError: while scanning a simple key in "./config.yml", line 4, column 1 could not find expected ':' in "./config.yml", line 5, column 3
Or when I run python3 main.py I get this:
Traceback (most recent call last): File "main.py", line 2, in <module> import chess ImportError: No module named 'chess'
Have tried starting from the default yml multiple times, error persists. Would be fine with getting a fix to either the python2.7 version or python3 version.

Book file option

Is the book file option working? I'm currently trying with an opening book and it doesn't seem to be working. Has anyone else tried?

error in "with logging_pool..."

I'm getting

Welcome ana-ka-bot!
Traceback (most recent call last):

with logging_pool.LoggingPool(CONFIG['max_concurrent_games']+1) as pool:
AttributeError: exit

Can't figure out what the issue might be. :(

Opening Books for Different Varients

Currently, if you use an opening book, it will play the moves for all variants. However, this is undesirable as different variants have different moves played in the opening for example atomic most commonly games begin with 1. Nf3 f6 but in standard if 1. Nf3 is played the most common continuation is 1. ... Nf6 . Thanks, TheM492017.

Feature: Add option to resign

Perhaps if uci bot wants to resign, it will send to api,

bestmove 0000

Followeb by

info string resign

api can terminate the game and award 1 point to the opponent.

I can revise my uci engine to support this.

For xboard engine, it has command to resign.

Or perhaps if api can access the score of the bot and the bot is sending the score properly to api, api can terminate the game based on settable score and number of times that the bot has been in a bad score.

LeelaZero only thinks on its own move, and not when it's an opponent's move

When I tried CPU version. There are fluctuations in task manager from 61% (on its own move) usage to about 20% (when an opponent has to move). If it was thinking while an opponent is making a move, it would be stronger, I think.

accepts all challenges at once

but only plays one. Confuses players and lichess alike

When running stockfish 9 64bit, it only uses about 25% of CPU power

Maybe it could be made to use more CPU power?

Why sending go movetime 2000

I have this log from my program. Game is played on TC 3+0. I am using lichess-bot 0.3.
Notice the,
go movetime 2000
is this intentional?

Later it sent the correct one.
go wtime 180000 btime 178850 winc 0 binc 0

Engine doesn't know that game is finished for time losses and resignations

Usually happens in faster time controls when someone gets flagged or the opponent resigns. The bot will continue trying to send moves to the server even though the game is finished. The Lichess API responds with a 400 status code.

Here's an example of trying to send a move after losing on time:

Game ply: 112, root temperature:  0.20

Bot periodically spends about 1 second on a move

It seems to happen to all bots: https://lichess.org/G3FeH6e3/black
And it happens with a certain period. Move overhead is set to 5000, and almost all of the moves are played instantly. But periodically these 1 second intermissions appear.

Upgrading to Bot Account

New here, hope this is the right place to post this, sorry if not.

I followed directions to set up the bot but ran into a snag. First, when I created an access token, I didn't have an option to select "Play bot moves", only download/read/write and email.

When I got to: run python main.py -u, I got the following message:
Valid token!
Something went wrong! status_code: 404, response: 404 - Resource not found
This is not a bot account. Please upgrade your Lichess account to a bot account!

suggestion: optionally share eval of the position on request (and more interaction)

A user just suggested that to me on lichess - sounds like a nice-to-have. Something along the lines of

user: !eval
bot: +1.23 [78% winning chances]

While at it, one could think about a lot more (optional) user-bot-interaction. Even something like a training bot.

user: makes a bad move
bot: are you really sure? you could still take back..

Auto decline takeback offers

Opening books

The engine is not using opening books, is there something more you have to do other than specifying the book name in config.yml?

Allow to specify supported time controls in exact time

Now we can allow "bullet", "ultrabullet", etc. But would be nice to be able to set it to < 1+1, for example.

Why not use weighted_choice instead of random choice in get_book_move?

Python chess has weighted choice in its polyglot module:

https://github.com/niklasf/python-chess/blob/master/chess/polyglot.py#L460

Why not use this instead of simple random choice in get_book_move:

https://github.com/careless25/lichess-bot/blob/master/main.py#L178

Don't accept challenges automatically against a bot except when mode is casual

Feature request:
My bot is not designed to play against a bot, it is designed to play against humans. It is weak around 1800 CCRL 40/4, and I am not improving its strength instead am trying to make it weaker.

There are bots that challenges it on rated mode which I don't really like as I can test engine vs engine matches on my pc at anytime, so I have enough engine vs engine games. Bot that challenges it in casual mode is just fine of course.

Another idea could be to develop a lichess bot protocol altogether where bot and api will communicate.
Example if there is a challenge to my engine named my_engine the api will send to my_engine,

challenge type bot name eeee rating n mode rated

where:
type is the type of player can be [bot, human]
eeee is the name of the engine challenging my_engine
n is the rating of the eeee engine can be [none, integer]
mode can be [rated, casual]

note that,
challenge type bot name eeee rating n mode rated

can be expanded to include tc, example

challenge type bot name eeee rating n mode rated tc b32

where:
tc value b32 can be a code,
b32 = Blitz 3+2
b52 = Blitza 5+2

Or other coding system design, above is just an example.

my_engine understand this as eeee is challenging me and it is of type bot and has rating of n on a rated mode. With this info I can decide whether I will accept the challenge or decline it.

or if a human challenges my_engine, the api will send,

challenge type human name hhhh rating n mode rated

The bot my_engine can reply with,
reply accept challenge type human name hhhh rating n mode rated

where:
reply [accept, decline] would determine if the game is a go or not.

If reply value is accept, the api can proceed the match.

If value is decline, api will inform the challenger,

reply decline [some message]

This is just a general idea details is totaly different thing. Perhaps adapt existing rules in fics and probably improve it further.

Bot cannot be run just by opening "lichess-bot.py" as before

Before there was a file named main.py, and I could just click it two times, and the bot would be automatically enabled. But now I have to go to PowerShell, then do
cd "directory"
./.venv/Scripts/activate
python lichess-bot.py
every time. If I don't execute "./.venv/Scripts/activate" before, I get this:

Traceback (most recent call last):
File "lichess-bot.py", line 8, in
import lichess
File "E:\chess\lichess-bot-master\lichess.py", line 14, in
import backoff
ModuleNotFoundError: No module named 'backoff'
PS E:\chess\lichess-bot-master>

And for "./.venv/Scripts/activate" to be executed, scripts should be allowed on the computer, and this is potentially dangerous for the system.

Race conditon

version has a race condition where: game_ends -> challenge_received -> check queue in worker and queue is empty -> cheque workers in main loop, all are busy -> insert new challenge into queue -> worker returns
in that case, there is a challenge in the queue and the worker won't pick it up.

Uci options don't work

I tried to change uci options:

ucioptions:
Threads: "1"
Hash: "1024"
Book File: "engines/book.bin"
Slow Mover: 10
Move Overhead: 5000

I tried also
Move Overhead: "5000" and "Move Overhead": 5000

I tried to add this in engine_wrapper.py with self.engine.setoption({"Move Overhead": 5000})

and in main.py with engine.send_line("setoption name Move Overhead value 5000")

But speed stays the same in all cases.

I tried different numbers, tried setting it to 0, to 1000. No effect.
