How would an engine do that can calculate like Stockfish and evaluate like Leela? We are about to find out. The still experimental but already extremely strong Stockfish+NNUE will debut in the coming chess.com Computer Chess Championship. It represents the attempt to incorporate an Neural Network into a traditional engine. Stockfish will do its search as quickly as ever, but its handcrafted evaluation function is replaced by a NN, a method first seen in Shogi engines. First tests have shown that Stockfish+NNUE may already be stronger than Stockfish/Leela on their own.
