The method
Chess fluency, like a language.
Nobody learns to talk from a grammar book. Children hear words used in real sentences, again and again, until the words are theirs. Good chess players learn the same way. They have seen "the knight belongs on f3" and "never weaken the king's pawns without a reason" so many times, in so many games, that the right move simply looks right.
You pick up good moves the way a child learns to talk: by hearing the reasons spoken, over and over, until they become instinct.
Where it comes from
In 1957 Irving Chernev published Logical Chess: Move by Move, a book that explained every single move of 33 master games in plain words. Generations of players learned from it, because it never said "obviously". It always said why. Principles came first, calculation second. Ideas came back game after game until they stuck.
chesstrainer uses the same method, spoken aloud and fitted to your games. (We're inspired by the book; we're not affiliated with its author or publishers, and we never reproduce its text.)
How it fits together
A trainer that plays you. Your first friendly game shows us how you think. The trainer plays at your level and talks you through the moments that matter, while you play, not after.
Three minds behind one teacher. Stockfish, one of the strongest engines in the world, checks every claim, so the coach never invents a variation. Human-style models (coming soon) show what players at your level actually do, so the advice is about the move you should find, not a computer's. A language model turns it all into short, warm sentences, with arrows and highlights drawn on the board as it speaks.
A plan that never runs out. The trainer reads your games, here and on Lichess, finds the habits that cost you the most points, and writes your week. When the week is done it writes the next one, from what you did and where you struggled.
A mix that keeps it fun. Games against your trainer, narrated master games, middlegame and endgame lessons, puzzles where you also name the idea, Woodpecker and Seven Circles cycles on your own pattern set, opening drills, and challenges to go play real games on Lichess and come back.
Memory that lasts. Every position you miss, from your games, from puzzles, from the masters, goes into your review deck. Spaced repetition brings it back right before you would forget it.
Proof it works. Your trainer rating, your Lichess curve, accuracy, blunders per game and a map of every theme: all visible, all going one way, we hope. Up.
For every age
chesstrainer is for anyone who wants to get better at chess, from a seven-year-old to a club veteran. There are no ads and no chat with strangers. Children under 13 need a parent's approval before they can start. We keep the data we need to coach, and nothing else. See our privacy policy.
