Don't just play chess. Train like a master. Chess King teaches the game the way strong players are actually built — with a rigorous, structured curriculum, not a random feed of puzzles. 147 complete courses take you from your first move to advanced play, step by step. WHY CHESS KING IS DIFFERENT Most chess apps let you play. Chess King trains you. Every course is a real lesson built on classical training methods refined over 30 years — the same approach behind CT-ART, the tactics trainer used by serious players worldwide. You don't just solve a position and move on. Chess King gives you hints when you are stuck, explains the idea behind the right move, and shows you the striking refutation of the mistakes you might make. That is how understanding is built — not memorized. WHAT YOU GET - 147 structured courses covering tactics, strategy, openings, the middlegame, and endgames, organized by level from beginner to master. - Chess King University: 7 guided learning paths and 44 courses that give you a clear, ordered route to real improvement — no guessing what to study next. - Interactive theory: read the lesson, then play the moves on the board yourself. Learning by doing, not just reading. - Thousands of carefully selected exercises with graphic hints and full explanations. - Play against the computer to put what you have trained into practice. - A progress report for every lesson, so you always see how far you have come. TRAIN ON EVERY DEVICE Your subscription, purchases, progress, and rating sync automatically across web, iPhone, iPad, and Android.
