Chess: Learn by Following

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.
