Frequently asked questions
Is using an engine to find moves cheating?
Using one during a rated game is cheating, and platforms ban accounts for it. Using it to study positions or review your own finished games is ordinary practice.
How strong is the engine?
This runs Stockfish, the open-source engine that has repeatedly won the Top Chess Engine Championship. At the depths it reaches here it plays far above any human.
Does it work on a phone?
Yes. The engine runs in the browser, so phones and tablets work too — they simply search more slowly than a desktop.
