EN-Tournament - Tournament mode engine test started!

This test makes it possible to estimate the tournament playing strength of an engine within one day. From various sources, I have selected 100 short variants of the most important openings, which also occur in the games on the well-known servers (Lichess, InfinityChess, PlayChess.com). I've even left out some of the most played lines, because 99% of the games end in a draw. At the last InfinityChess Engine-Masters tournament, only 12 variations were allowed, where White had an advantage of +0.80 each (Stockfish analysis). This advantage was enough to win 4 games out of 120 played (I didn't include losses due to operator error and disconnects). This is the trend today in computer chess on the servers! But as long as there are such tournaments there, as well as such engine game rooms where all possible opening books are allowed in freestyle mode, I will test the engines for such games!

I test with 60s/position on 14 threads

06. May 2023: Stockfish 16 (use 1536 NNUE) vs Stockfish dev 010723 (use 2048 NNUE)
Hardware Ryzen 2700, hash 512 MB, time control 5m + 0.1s
Final result: +5 =191 -4 as seen by Stockfish 16 --> eng-eng live picture.
SF 16 uses a smaller NNUE network otherwise the engines are identical.

25. July 2023: Network Test - Dimension 2560 vs Dimension 2048

I did another test today. Already in my first test, the new unofficial dimension 2560 won against the SF dev standard network with dimension 2048. My private engine Smile XPro is not identical to SF dev. It is a modified SF version, and adapted to the new NNUE Dimension 2560.

SF dev used network "nn-c38c3d8d3920.nnue" (Dimension 2028)
Smile XPro used network "nn-1ceb1ade2048.nnue" (Dimension 2560)

After 36 games, Smile XPro was able to achieve a +4 lead. So it is clear to me that the new NNUE net with dimension 2560 plays better than SF dev when played with enough time. Bullet games often end randomly, in 10 minute games the engines take more time (sometimes even more than 60s per move). Ponder ON is very important to me, because we play with it on all servers.

The games was played on Ryzen 2700 with the Fritz 18 GUI.
