bajeEngin

Author - Chandan Das

A simple UCI chess engine written in pure C. Though it was written back in 2025, I'm licencing it on 2026

Current version: 0.07

Features

• Minimax search with alpha-beta pruning
• Basic evaluation with material + piece-square tables
• Supports castling, en passant, pawn promotion (to queen)
• UCI protocol compatible (works with Arena, Cutechess, Nibbler, en-croissant , etc.)
• Fixed depth search (currently depth 6)

How to Build & Play

gcc -O3 -o bajeEngin bajeEngin07.c -lm

or just use the Makefile You can play with it on terminal as,

make play
# or
bajeEngin play

This way you can play in CLI.

But I will prefer it to play in GUI. Such as,

Arena, Nibbler, en-croissant

Chose /pathto/bajeEngin in their add engine option to play in GUI.

Caution

If It takes too much time to make move try changing the depth to smaller vlues
