Stockfish 15 NNUE is now powering Game Review

UPDATE: We have noticed that Game Review is not loading sometimes due to this change. We are rolling it back until we have a fix. Thank you all for your feedback and patience.

Hi all,

We recently made some technical upgrades that allows us to upgrade the chess engine powering Game Review. Game Review is now powered by Stockfish 15 NNUE, the strongest chess engine in the world. This technical upgrade will also let us quickly upgrade to newer Stockfish versions when they are released. We hope that continually providing users with the most advanced, accurate chess engine will mean Chess.com is the place to come for trustworthy chess analysis.

There is nothing you need to do to activate this upgrade; it happens automatically. Also, there should be no effect on your Game Review, other than having stronger analysis. As always, please let us know if there are any issues with Game Review that pop-up due to this change .
