Stockfish Classic is leading CCC No-Castle 5|2

https://www.chess.com/computer-chess-championship

1 Sf-Classic  70.0/94  74.5%
2 Stockfish   68.5/94  72.9%
3 Komodo dev  64.5/94  68.6%
4 Fire dev    55.5/94  59.0%
...


Versus Fire: Stockfish Classic +5 =3 -0 6.5/8, Stockfish +2 =6 -0 5.0/8.

The book opening is the same as 1.Nf3 except both sides have moved both their rooks -No Castle-, then put their knights and rooks back to their original squares.

Looks like a big chunk of NNUE's strength comes from positions where it was trained for castling.

Yes. And I was impressed with Classic's result at CCC, normal chess (-21 Elo to Stockfish).

Maybe the 1 ply book was not so good for NNUE either.
Or maybe fishtest to CCC compresses that much.

(And so far I am a little under-impressed with Stockfish at TCEC 19 SuFi:
tied through game 47 then a win for 24.5-23.5 of 48. https://tcec-chess.com
TCEC 18 SuFi: Stockfish Classical 53.5-46.5 of 100 https://tcec-chess.com/#div=sf&game=1&season=18 )

CCC CPU Blitz Madness (1 ply book, normal chess)
1 Stockfish (3862)             122/156
2 Stockfish Classic (3781) 118.5/156
3 Komodo ... 14 Wasp

To summarize my post here: http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=33663 :

Another strange thing: CCRL Blitz (today) http://ccrl.chessdom.com/ccrl/404/rating_list_all.html :

1  Stockfish 12 64-bit  3666  +22  −22  89.3%  −325.7  21.0%  1240  
65.0%
   Stockfish 12 64-bit 8CPU  3658 +28  −28  63.4%  −75.1  70.7%  335

They rated 12 1CPU versus many lesser CPU engines all with 1CPU (80%-94%).
but they rated 12 8CPU versus only 6 engines (so far), 5 GPU engines on a RTX 2080, and Komodo 14 8CPU (+81% 45.5/56).
