Analysis
Puzzles from your own game
Paste a game – Stockfish searches it in your browser for positions where one move is clearly the best, missed chances too. Nothing leaves your computer.
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.
