Stockfish NNUE

On this page you can download one of the latests strongest version ready to use via the download button below.

A new revolution in computer chess is taking place, in our opinion it will (once again) change computer chess dramatically the coming years looking at the first results. In a nuthshell, a few smart people more or less captured Stockfish evaluation in a neural network. Progress goes incredible fast, the latest well tested version is now ~95 elo stronger than Stockfish 11 within just 14 days. So stay tuned.

The current links are:

1. Nodchip for the latest versions.

2. Sergio for the current best networks.

3. Talkchess forum, the place were the new development is discussed.

4. Initial start of the progress with the henk-2706 network.


To add or replace another Sergio network file the most simple way is to rename the new network as nn.bin in the eval folder.

You are reading well, the best current network version is ~99 elo points stronger than the official Stockfish 11 and a lesser strong version immediately took over the first place from Lc0 (and friends) on the CCRL rating list.


There is a new future for the AB engines without the need of expensive GPU cards.

For experienced users

If you are not sure which executable to use choose the popcount version.
