When enabled, an engine running on the cloud will play against you to add variety to the game play. There are three engines: Stock Fish 12/15 (NNUE), Lc0 v.28 and Fruit. Opening book is still used even for cloud engines and Stockfish 10 may tag in during the middle game if the cloud engine takes too long to evaluate. Cloud engines will play according to the selected strength profile when possible. Fruit is only available for the strongest settings.
