Dear Chess Friends,

As usually, I am pleased to announced that,

Another new NNUE competition of 3300+ Elo

The previous results can be viewed XIII / XIV

Some Notes:

Main target: testing latest releases,Total: 21 chess engines!

And almost all BMI2 vers, played via their default EvalFiles

All engines used to play with Balsa suite (reversed colors)

Note also that just out of curiosity, two SF vers. more tested:

SF310720 is the last NON-NNUE vers. plus the other one is

Stockfish 260820, which belongs to the 1st NNUE releases..

Now we can compare the Elo difference between them...e.g:

In 2 years, SF (NNUE vs NNUE) is improved approx.130 Elo

SF (NON - NNUE vs NNUE) is improved over than 210 Elo

Sure these Elo values are based on Blitz TC, I mean in faster

Or slower time controls SF Elo improvements can be different

Plus via weak openings, Elo diff. can be different,more Details

Btw, Stockfish 110922 has no any single loss..Unbelievable!

Anyhow, just a fun competition...enjoy...!)

The Winner of CS XVI: Stockfish - My Congratulations to SF team!
