STARTING FROM ZERO

Italian Game

Saved on this computer
THE ONE-SENTENCE IDEA

Fast development toward f7, then a central d4 break.

Italian Game gives a beginner a clear map from move one: where the pieces belong, which pawn break matters, and how to react when the opponent refuses the main line.

PAWN STRUCTURE

Open center with active bishops

Pawn structure tells you which files and diagonals will open. Use it to choose a plan instead of guessing.

YOUR PLAN

Develop, castle, prepare d4, and attack only after the center is ready.

Before every move: answer the threat, check king safety, then improve the least-active piece.

Premium explanation layerUnlock move-by-move deeper reasoning, move-order risks, evaluation notes, two additional opponent scenarios, and a decision checklist.Compare plans →

CHROME COMPANION

Every finished game becomes a lesson.

The extension notices when a Chess.com game ends, retrieves the completed public PGN, and opens a private visual review. Free reviews are fixed to the locally bundled Stockfish 18 Lite engine; Quick, Balanced, and Deep change analysis depth, not engine version. It never gives assistance during a live game.
