Analysis
The analysis board.
Enter a game move by move or paste it as PGN, set up a position and let Stockfish think along. Share the position as a picture, link or QR code – everything stays in your browser.
Move the pieces on the board. Another move where the line goes on becomes a variation – nothing is overwritten.

Good to know: the search in your browser works with other, simpler methods than the search that made the puzzles of chessepolis – it looks at each position for a shorter time and leaves out some of the checks. So it may miss a strong move or not take a position as a puzzle.
The search follows the rules of chessepolis, but with the Stockfish of your browser – one to three minutes on a computer, longer on a phone. When you share a puzzle, all of it is in the link; it always says that a visitor made it.
