A chess engine written in C++
This chess engine implements a variety of chess programming concepts while maintaining a simple to read codebase.
- Bitboard-based board representation using 64-bit integers
- Magic Bitboards for sliding pieces (bishops, rooks, queens)
- Pre-computed attack tables for leaping pieces
- Special move handling (castling, en-passant, promotions)
- Alpha-Beta search with enhancements (LMR, PVS, Quiescence)
- Material and positional scoring
- Move ordering with MVV-LVA, killer moves, and history heuristics
- Transposition Table with Zobrist hashing
- XORSHIFT32 for fast pseudo-random number generation
- Position caching and move ordering
- Built-in PERFT testing for movegen validation
- UCI protocol support for chess GUI compatibility
- Time management system
- Iterative deepening search
- Neural network evaluation (NNUE)
- This engine is based on Code Monkey king's Bitboard Chess engine, An amazing project which makes chess engine programming accesible for all!
