Five foundations for a better plan.
Each guide includes a starting position, annotated moves and practical takeaways. Read the full explanation here, then open the matching interactive lesson.
Piece development and king safety
Bring your team, shelter your king
Use each opening move to give a piece a job. Prepare the king’s shelter, then finish development rather than attacking alone.
Read the lesson
Pawn structure and pawn breaks
Read the pawn map
Pawns shape where pieces can work. Follow their support links, then use a prepared pawn break to change the position.
Read the lesson
Rook activity and open files
Give your rook a route
An open file has no pawns. Use it to improve a rook, expect resistance, and look for a safe entry square rather than an automatic win.
Read the lesson
Opponent plans and prophylaxis
Ask what they want next
Before improving your own position, look for the opponent’s next useful move. A small preventive move can make that plan harder.

BEFORE YOUR FIRST MOVE
About these lessons.
Created by Gal Itach at Valorem Apps.
The study guides remain readable without JavaScript. Interactive boards need JavaScript and a modern browser.
Are these chess lessons free?
Yes. The browser lessons, guided practice and study downloads on this page are free to use. You do not need an account or the Pawnpetal app to start.
Where should a beginner start?
Start with board fluency if square names or piece moves are new to you, then explore the rules lessons. Before working on a plan, practise the optional safety scan: king, threat, landing square. The five foundation guides introduce central control, development, pawn structure, rook activity and the opponent’s plans.
Is this the same curriculum as the Pawnpetal app?
This is a separate browser learning experience with its own released lessons and examples. It does not reproduce the native app’s curriculum. The iPhone, iPad and Mac editions have their own features and requirements, described on the Pawnpetal app pages.
How does the interactive practice work?
Explore an idea, make guided decisions, then try a fresh position when available. Some fresh checks need preparation first. See and Try remain available for exploration. Progress records distinguish exploring a lesson, completing a flow and finding a goal; they do not certify mastery.
Will my progress be saved?
The garden saves progress and the last selection in this browser on this device when local storage is available. Short guided flows and exercises restart from the beginning on reload. There is no account or cross-device sync. Clearing browser data removes the saved progress.
Can I play a full chess game here?
The browser garden is for lessons and bounded position practice. It does not offer full games or computer opponents. Visit the Pawnpetal app page to compare the native editions and their play modes.
Are the example moves forced or engine-certified?
The foundation lines illustrate legal chess ideas. Opponent replies are authored examples, and other replies may be possible. These are not engine-certified best lines, promises of a win or a complete chess course. Each guide explains its own limits.
