Chess game with pygame library made from zero. The game has an AI engine option.
That's was my first python project. I did this project because I love chess and I wanted to practice and test my python skills.
the project is ready to use.
All you need is python, pygame package and my code :) Run the commands below to install and run the game.
git clone https://github.com/guykrinsky/BeCheZ.git
pip install pygame
python main.pyif you want to play an online game, first you have to run server.py. After that you need to change the ip of the server in protocol.py, and than you can play.
First thing, every piece has a score that represent it's value, this is the base of the engine.
In addition, a knight in the corner of the board doesn't equal to a knight in the center, so the piece's score dependents on it's position.
The score of the game is the sum of the white team's pieces minus black team's pieces, the black player want the score to be minimal and the white maximal.
This is how the bot works, for every move he can do he checks every white team move, and for every white move he checks his own moves, and so on until 1 to 5 future moves. Every player will do his best move, white player will want to do a move that lead to max score and the black player to the min score. That called min-max algorithm.

This isn't over ;), we can disqualify some paths by Alpha–beta pruning.
This part is more complex, you can read here the more boring staff: (https://en.wikipedia.org/wiki/Alpha%E2%80%93beta_pruning).
After one yaer I got back to the project. I learned about network in python, And I wanted to upgrade my chess project to have an online option. Every client communicate with the server. there isn't a piece of information that being directly send from one client to other. The communication with the server is done by using the protocol, both sides. Since my computer doesn't have an public IP, I can only play against other computer at the local server. Because I run server.py only in my local server, if you want to play an online game, first you have to run server.py. After that you need to change the ip of the server in main.py, and than you can play.
