Next move finder
Chesspedition's next move finder shows the best move in any chess position. Set the pieces up on the board or paste a FEN, choose who is to move, and press "Find the best move". Stockfish 19 searches the position in your browser to depth 18 and names its move, the likely continuation and who stands better. Free, no sign-up.
How to use it
- Set up the position: choose a piece and click squares, or paste a FEN and press Load. "Starting position" and "Clear the board" give you a quick start.
- Choose who is to move and which castling is still allowed.
- Press "Find the best move". The search shows the depth it has reached, and when it finishes the move's two squares are marked on the board.
- Under the move you see who stands better and the line the engine expects. "Analyse this position" opens the same position in the analysis board, where the engine keeps going deeper and shows more than one line.
Questions
- Which engine finds the move?
- Stockfish 19 with its smaller ("lite") network, running on your own device to depth 18. A longer search can change the answer in sharp positions, so for a position that matters open it in the analysis board and let the engine go deeper.
- Is my position sent anywhere?
- No. The engine runs inside your browser, so the position stays on your device.
- Can I use it during a game?
- No. Getting help from an engine while a game is being played is cheating, online and over the board. Use it to study positions and to check games that are over.
- Why does it say my position is impossible?
- A game can only be played from a position with exactly one king each, no pawns on the first or last rank, kings that are not next to each other, and the side that has just moved not in check. The page names the first rule your position breaks.
