Chess game analysis uses a powerful chess engine to evaluate every move in your game. By calculating centipawn loss and identifying blunders, inaccuracies, and best move alternatives, engine analysis shows where the position shifted and why. Strong players use computer analysis to understand tactical mistakes, improve opening choices, and refine endgame technique. With modern engines like Stockfish, players of all levels can review games with grandmaster-level precision.
