Chess Trainer: Tactics & Play

Chess is not learned from a book — it is learned on the board. Chess Trainer makes you PLAY every idea: every lesson ends with positions you must win yourself, and every pattern becomes a move your hands know. THE ROAD Short lessons you play, not read. Watch each idea arrive move by move, replay it as often as you like, then prove it — three positions where you deliver the mate yourself, and a boss game to seal the unit. CHECKMATE PUZZLES Mate in 1, 2 and 3, every solution engine-verified. Learn the 29 named checkmate patterns — back rank, smothered, Anastasia and the rest — and collect them in the Mate-dex: a card is engraved the first time YOU deliver that mate in a real position. PLAY • Our own on-device bot: plays anywhere, no internet needed, free forever. • Rated levels from 1350 to 2850 Elo, powered by Stockfish — the world's strongest open-source engine — running on our servers. • Pass & play with a friend on one device. GAME REVIEW Every move graded, from Brilliant to Blunder, with an accuracy score for both sides. See what the engine would have played, step through the game move by move, and keep the review forever — reopening it is free, even offline.
