About The Project

Chess.ai is a portal in which you can play chess with a friend or with a bot. You can sign up on the portal using simple user name and password. The bot uses minimax algorithm with alpha beta pruning and is hosted on backend. The games played are stored in a NoSQL database, which your can retrieve and analyze.

Play with Friend

Here are some issues in the project which you can contribute on :

• The AI needs to be optimized. Currently it takes 1-2 seconds for inference.
• There is a timer of 5 minutes during which you can decide your next move. The timer should be variable according to user needs.
• I am not a professional chess player. I have implemented all the rules of the game as well as castling, en passant and pawn promotion.But still if you feel some rule of the game is missing or not working as expected, do contribute. Such fixes of features are always welcome !
