The NNUE evaluation was first introduced in shogi, and ported to Stockfish afterward. It can be evaluated efficiently on CPUs, and exploits the fact that only parts of the neural network need to be updated after a typical chess move. -[The nodchip repository](https://github.com/nodchip/Stockfish) provides additional -tools to train and develop the NNUE networks.
