01 / Set the scene
Start from the opening position, try a sample, or use Set up position to place your own pieces. You can also import a FEN position or a PGN game.
SMALL HABITS. STRONGER CHESS.
Make curiosity your advantage.
A simple rhythm for turning any position into something you understand.
Think first. Then ask the engine.
Choose two or three candidate moves. Imagine the reply. Only then compare your thinking with Stockfish. The insight comes from the difference.
02 / Explore your idea
Drag a piece, or click its square and a destination. Dots show legal moves. When a pawn promotes, choose your new piece. Use the arrow controls to revisit any move.
03 / Find the insight
Show best move runs Stockfish directly in your browser. A positive score favors White; a negative score favors Black. M means forced mate. Apply the move, then play the reply.
04 / Keep the discovery
Save a named scenario to your device library. When your workspace has cloud accounts connected, sign in to save across devices. Export PGN to keep a portable backup of the full line.
