Cheess Engine

Custom chess engine following FIDE chess rules implemented in plain Python with pygame library for visualization.

Normal game mode

Game mode to interact with visual chess board via mouse click. Moves and pieces are highlighted on chessboard using pygame.

Perft (Performance testing) of engine

Automatically evaluating and testing the chess engine using all allowed moves. Compares to challenging test cases to evaluate edge case situations that rarely happen (En-passant, pins, hidden checks, double checks etc.). Number of recursively searched nodes are compared to Stockfish (a strong chess engine) to ensure correct behaviour.
