Im on a macbook, so could i have any advice to build a strong chess engine from scratch?

I recommend you to start using Python, this Reddit has lots of info that could help you: https://www.reddit.com/r/chessprogramming/comments/1b4n1cw/guide_for_chess_engine_in_python/

Good luck !

Hey @zBotXTRON — great question!

I agree with Jordi, and I’d say it really comes down to what you are most comfortable with. There’s no single “correct” setup — just tools that make you more productive and excited to build.

Here’s what I use:

  • VS Code – lightweight, flexible, and highly customizable

  • Python – great for prototyping and AI integration

  • Pylance – adds smart IntelliSense and type checking

  • GitHub Copilot – like an AI-powered coding assistant

  • ChatGPT – my go-to for debugging and brainstorming

That combo has saved me hours of work — especially Copilot and ChatGPT for speeding up repetitive tasks or helping out when I get stuck.

That said, don’t feel locked into anything. I have a programmer in my club Tricky_Dicky who’s doing creative stuff with Excel and VBA for chess analysis and automation. So honestly, there are no wrong answers here. Use what works best for you and enjoy the journey.

My biggest advice? Find a club or community focused on developers. Surround yourself with people who are experimenting, building, and sharing. You’ll learn faster and stay motivated.

If you ever want to connect with like-minded devs, check out the club I help run — it’s all about coding for Chess.com, building tools, and supporting each other.

Happy coding — and let us know when your engine starts crushing games! 😄

WARNING these are from ChatGPT so they can be riddled with coding errors so debug.

As an example I asked AI and Here’s a lightweight chess engine in Python with basic features:

  • Parses and plays legal moves using the python-chess library

  • Uses a simple minimax search with material evaluation

  • Can play as either white or black


🔧 Requirements

pip install python-chess

}

def evaluate_board(board):
    value = 0
    for piece_type in PIECE_VALUES:
        value += len(board.pieces(piece_type, chess.WHITE)) * PIECE_VALUES[piece_type] # count white pieces
        value -= len(board.pieces(piece_type, chess.BLACK)) * PIECE_VALUES[piece_type] # count black pieces

            move = choose_best_move(board, 2# engine plays white
            print(f"White plays: {move}")
        else:
            move = choose_best_move(board, 2# engine plays black
            print(f"Black plays: {move}")
        board.push(move)

    print("Game over!")
    print(board.result())

    play_game()
 

🧠 Notes

  • This is very simple — no opening book, endgame knowledge, or pruning.

  • Evaluation only considers material. You can add:

    • Piece-square tables

    • King safety

    • Mobility

  • Increase depth for stronger play (but slower).

  • Replace minimax with alpha-beta pruning for better performance.

You want to 100% use python3 inside a linux container.

I am not a super experienced linux dude. VS Code is FREE and you just set up an app. What are the befits of doing a whole linux setup?

I would do it, but I would need a compelling reason.

I have VS Code, but it is new to me, so are there any specific things i need to set up a engine on there?

Yes I have a list. I will get it for you. Sorry just saw your post I have been traveling.

First off the questions.
