Chess Opening Database

THE ATLAS

The world's first chess openings database where every move is explained. Learn the ideas, not just the moves.

Our Philosophy

Understanding Over Memorization

Traditional opening resources tell you what to play. We tell you why.

The Why Behind Every Move

Each move comes with a clear explanation of its purpose—attacking plans, defensive ideas, and positional goals. No more blind memorization.

Build Real Understanding

When you understand the ideas, you can adapt to any opponent. Forget about your preparation? No problem—you know the plans.

Navigate Any Position

Learn the strategic landmarks that guide your play. Recognize patterns, understand imbalances, and find the right plans instinctively.

Please note that there is still some possibility of some explanations having minor mistakes or grammatical errors, which you can report to us.
