Chess Coach is your AI chess coach. Learn with guided chess courses, play bots or real people, solve chess puzzles, and understand every mistake in plain language. CHESS COURSES — LEARN IN ORDER Guided lessons across levels, from the rules to club play. You start with First Steps, learning how the pieces move, then move on to Beginner for tactics and openings, on to Intermediate for pawn structures, endgames and openings you learn from both sides, and on to Advanced for calculation and plans. Every lesson mixes theory, exercises and play on the board, and you don't move on until the position works. The first course is free. OPENING LAB Play your repertoire against an opponent who plays like a person, not like a flawless machine. Real positions and real mistakes — which is where an opening is actually learned. ENDGAME LAB The 100 chess endgames you must know, one by one: king and pawns, rook, queen, bishop and knight. Learn the technique with the position in front of you, then practise it with a different exercise every time — some you win, some you have to hold, just like in a real game. MIDDLEGAME LAB 25 pawn structures — the isolated queen's pawn, the Carlsbad, the hedgehog — each one explained the way a book would: what it is, who stands better and what each side should be trying. Then you name them in positions from real games, and the board marks the pawns that give it away. Every structure brings its own tactics, and a game you can play from it against a human-like opponent. DECISION TRAINER Read the position, calculate, decide: pick your move, play the line five moves ahead — yours and your opponent's — and ask why each move is played. PLAY BOTS — OFFLINE A roster of opponents from beginner all the way to grandmaster. Pick who you play, your colour and your pace: bullet, blitz, rapid, classical or no clock at all. Works without internet. PLAY CHESS ONLINE HU Chess, our own online play, with bullet, blitz, rapid and classical, your own rating and level-based matchmaking. Prefer Lichess?

It grades your moves and gives hints without spoiling the answer. And you can ask it anything about chess. Powered by Gemini, OpenAI, Claude, DeepSeek and Qwen, and it adapts to your level: — Beginner (800–1200): simple concepts and basic tactics — Intermediate (1200–1800): strategic ideas and positional play — Advanced (1800+): deep analysis and theory CHESS PUZZLES — STREAK, STORM & 30+ THEMES • Daily puzzle and a mix at your level • Streak: how many can you solve without missing? • Storm: three minutes against the clock • Over 30 themes: pin, fork, skewer, discovered attack, sacrifice, back-rank mate and more • Pawn, rook, bishop, knight and queen endgames • Your puzzle rating, so you can watch yourself improve OPENING TRAINER Hundreds of chess openings organized by ECO code, in three phases: learn with guided arrows, practise until you play it twice without errors, and master it through quizzes. Explore any opening in the Lichess database, with millions of games.
