How strong is the AI?
ChessUp 2 has a built-in offline AI that is strong enough to beat most players. Ready for an even greater challenge? When connected to WiFi, the ChessUp AI is powered by a chess engine called Stockfish, which has consistently ranked first or near the top of most chess-engine rating lists and, as of October 2022, is the strongest CPU chess engine in the world. It has won the Top Chess Engine Championship 12 times and the Chess.com Computer Chess Championship 19 times.
