Some ideas

[PGTBoos]

Was looking at the code i'm on a jupyter notebook though.
Could it be converted to it? ,
I've still not cracked the looking ahead for moves..

Though for your code.

• Maybe an idea, what if all the potential moves was just selected from list(board.legal_moves) ?
• Bishop/Knight values, how about adjusting it during the game a single bishop is less then a pair
  its not just comparing number off bishops vs knights, their value change slightly. (i'd even prefer 2 knights end games).
• Not sure if you allready do this
  If you check several moves ahead, one doesnt need to recalculate if a specific move is indeed played, top results can be cashed
  and if so one can expand on previous results, which might even then get a bonus 1 level deeper.
• Not sure if you take it in the calculation, diagonal pawn walls, might get a higher peace value.

No, I don't see a good, practical reason converting this project to a Jupyter notebook. Is there a good reason why you would like to have it converted to a Jupyter notebook?

Maybe an idea, what if all the potential moves was just selected from list(board.legal_moves)

I noticed that board has no attribute legal_moves. Could you please point to a file and line number where you can find that? Or is this an intentionally introduced new attribute? If so, please describe how it should look and behave.

This is a good idea, if you wanna do it and have time for it, you can open a PR.

I didn't see this kind of behaviour anywhere in the code. It sounds like a good idea too, but I guess the problem will be that right now it wont change much, as you can read in the README.md under Technical stuff it's a very basic and slow AI. So my apprehension is that it needs to much time for often recalculations when the AI wrong predicts the best moves and with a too low lookahead cache the AI can recalculate things fast enough that we don't need it (As seen on the screenshots, 2 moves lookahead is ok to calculate but 3 and above is very time consuming and eventually for this it could make sense to use a cache. But if we choose a number higher than 3, players would wait too long for recalculations).

This is again a very interesting idea. if you wanna do it and have time for it, you can open a PR.

What is a PR ? For me it be nice on jupyter since all neural network lives there at my pc. Might attract other Devs too if published like that. Outlook voor Android downloaden<https://aka.ms/ghei36>

What is a PR ?

PR means Pull Request.

For me it be nice on jupyter since all neural network lives there at my pc.

It might be better for you because you wanna integrate sonething, but would be a pain for me to maintain.
e.G.: Jupyter Notebooks can not be reviewed as .py files. It is much harder with Jupyter Notebooks. Also as far as I understood, Jupyter Notebooks don't really have the concept of "modules". Every piece of code essentially would have to be written twice: once for the normal python code, once for the Jupyter Notebook.

Also I think Jupyter would force people to use a workflow not everyone uses or wants to use.

Might attract other Devs too if published like that.

That's a good point, but unfortunately I don't think that it is worth the additional work for maintaining it.

If you want to have a Jupyter Notebook version of this project, please do it on your own, but I don't gonna do the extra maintaining work and also I don't wanna load extra work on the contributors when they have to write their code two times.

[PGTBoos]

Ok fair point, 2 versions is indeed a lot of work to maintain.

Oh and about legal moves this is how I do it at my current chess jupyter notebook.

!pip install chess
import chess

board = chess.Board()
board.turn == chess.WHITE
print(str(board))
list(board.legal_moves)
move = list(board.legal_moves)[0] # take the first move (with no score calucalation at all)
print(move.uci())

[ClasherKasten]

!pip install chess is wrong.
The package name is cl-chess, so the correct command would be !pip install cl-chess.

Sorry, but i forgot to mention that the PyPI package didn't get updated for quite a while. To use latest changes, I would recommend to install from source (through cloning the repository and pip install <path-to-cloned-repository>).

After some experimentation, I got it to work in Google Colab. Here's the code:
!git clone https://github.com/marcusbuffett/command-line-chess
%cd /content/command-line-chess
!pip install .
!chess

For only installing it, and not needing the code, cloning isn't required, because pip can install from git repositories. See documentation for this here
