Stockfish-NNUE is a CPU-friendly neural net version of Stockfish that is inspired by a Shogi engine..
What happens when you combine the brute-force computing power of Stockfish with the positional understanding of AlphaZero (or Leela Chess Zero)?
The chess world is about to find out!
Stockfish+NNUE has broken new ground in computer chess by incorporating a neural network into the already incredibly powerful Stockfish chess engine. This hybrid chess monsterpiece is estimated to perform better than the current Stockfish 11 who recently defeated Leela Chess Zero in the TCEC, giving it a solid claim to being the strongest chess engine in the world
Stockfish+NNUE is a creation by H. Noda (and others). Instead of being merely a "piece-counter," it looks at the whole position at once, in the style of Leela Chess Zero. But, thanks to new tricks borrowed from shogi engines, Stockfish+NNUE is able to maintain incredible speeds on the Chess.com Computer Chess Championship's strong hardware, calculating something like 60 million positions per second, compared to 40,000 positions per second for Leela Chess Zero or 100 million positions per second for regular Stockfish. This allows it to keep its tactical ability while running on standard CPUs.
