A very short test with an amazing chess engine - the latest Stockfish development version (03-06-2020) having a cpu NN. NNUE = efficiently updateable neural network backwards.
THANK YOU nodchip !

Stockfish NNUE 2020-06-04 = A SUPERB ENGINE ! Empty Problem in Fritz16 gui

Post  Scipion75 on Sun Jun 07, 2020 1:21 am

Hello,
Thank you for info. For some reasons, the engine (same name as yours) doesn't load in Fritz 16.... It is UCI engine isnt' it ?
Btw what's difference between kp and Halfkp engines ? I saw no explanations on Github.
Do I need to place other files in same directory as engine to be able to run it (like Lc0 networks) ?

-Yes, Stockfish NNUE is an UCI engine.
-You need a CPU having Intel's Haswell architecture (BMI2, AVX2 instruction set).
-kp version uses a small net (nn.bin)
-halfkp engine architecture uses the big net (nn.bin=20 MB).
-You need only the engine, the "eval" subfolder (having nn.bin).........and a logo (if sunny ).
-A small test tournament is taking place on my computer comprising both versions (kp & halfkp) + Fire 7.1 & Komodo 13.3
-Stockfish NNUE (both versions) is a very-very-very strong engine. I think it's a new way in computer chess. Lc0, FatFritz, Allie & co use expensive GPUs. Stockfish uses only a good CPU.
-Stockfish NNUE doesn't need to use a book (book.bin, GUI book or similar).

Thank you it works indeed. First two test games though were disappointing .. Played 2 blitz games 3+3 vs SXPro-NN ... 2 losses for SF, and some weird suicidal pawn advances very early in games. Did you change any of the default settings ? I will try halfkp too, but I have to find this 20Mb nn.bin first.

EDIT - Much better with the halfkp engine. Only draws so far vs S-XPro NN, with strong attacks each time. Very interesting. Nps though is much lower than SF or S-XPro engines.

There is a large thread on the Talkchess forum dealing with Stockfish NNUE here:

I believe ChickenLogic is the author of the 20 MB net. Here is a link:

The Talkchess host is/was allegedly having problems with hackers, so they imposed an IP regional block in certain areas of the world.  I live in western Canada and access has never been a problem.  But it has for many others - especially in certain parts of Europe. Many members have been using a VPN or Tor to get access.

There is a six page thread entitiled "Forbidden" on the Talkchess Forum about this problem! Very Happy

I understand. So Europeans do not have access. Thanks for the clarifications!
