Stockfish 12 NNUE: Play and Analyze for Free

Stockfish 12, which is also known as Stockfish NNUE, is the latest version of the world’s most popular chess engine. Here at DecodeChess, you can play and analyze with Stockfish 12 for free!

What is Stockfish 12?

The Stockfish team constantly updates their chess engine, making it stronger in terms of its rating. With Stockfish 12, which was released in August 2020, the team announced that it’s stronger than the previous version by almost 100 ELO points, which is very significant. The big change in this release is the addition of an efficiently updatable neural network (NNUE).

Until NNUE, all chess concepts that were programmed into Stockfish, were weighed by humans in a very limited manner. With NNUE, the same chess concepts are integrated into the neural network, which weighs them by itself.

What is it like in terms of playing style?

The development team at DecodeChess reports that Stockfish NNUE is an aggressive, sacrifice-oriented playing machine. They also noticed that many of its moves are less intuitive. This makes it a very interesting chess program, as it might introduce new ideas which so far weren’t adopted by the chess community. This brings to mind the impact that Alphazero had on the chess community back in 2017.
