C++ Chess Engine

This is a chess engine I built in C++ as a personal learning project. You can play against the engine on Lichess under the name "Grand_Mater_Bot". (Note: the bot is currently not online 24/7.)

Features

  • Bitboard-based representation for each piece type
  • Legal move generation for every piece, castling and en passant
  • Check, checkmate and stalemate detection
  • Minimax algorithm with alpha-beta pruning
  • Evaluation with piece-square tables, king safety and pawn structure
  • Time management for every move
  • Quiescence search for captures
  • Transposition tables using zobrist hashing
  • UCI connection to Lichess for playing against other bots

How to Compile and Run

Make sure you have a C++ compiler installed (g++).

To compile and run:

cd chess-engine-in-cpp
g++ -O3 main.cpp uci.cpp board.cpp zobrist.cpp tt.cpp -o engine.exe
.\engine.exe
