What it does
365Chess provides a chess-games database, opening exploration, position search and training tools for tactics and endgames.
Position search is useful when you reach an unfamiliar middlegame and want to see whether it has appeared before. Opening statistics answer a different question from engine evaluation: they summarize recorded games. Use the matching games as study examples rather than a guarantee that the most common move is best.
When you already have the game, import its PGN; for one position, use FEN instead. Those inputs avoid reconstructing a position move by move before studying matching games or opening statistics.
