One move at a time. Chess gets clearer. Chess Master breaks every opening and endgame into four learning stages — Follow, Understand, Practice, and Challenge — so you meet each line four times in a row and the moves start to feel inevitable. Study the line, understand the reasoning, reproduce it from memory, then face an AI that plays the same opening against you — learning and real matches in one flow. Four-Stage Learning Flow 1. Follow — Tap each move in sequence, tracing the line by hand. 2. Understand — Watch the line auto-play while you read why each move wins. 3. Practice — Reproduce the sequence from memory, no hints. 4. Challenge — Play an AI that uses the same opening against you. Main Features - Four-Stage Learning Flow: Meet every opening and endgame four times through Follow, Understand, Practice, and Challenge until the moves feel natural. - Opening and Endgame Courses: Sixteen classic openings and sixteen essential endgames, every move annotated with the reasoning behind it.
