We're getting very strong results for Stockfish 191210 at CCRL 40/15 on 1CPU. There are the error margins of course with the lower number of games.
Where ?

I only see 4CPU list...

Now You are testing 25.12. SF. But there is only one patch with Elo +0.41. Better to wait?
On NCM there is a +5 Elo jump... :wink:
NCM has a ±4 error.
Indeed Stefan Pohl :

"Latest Website-News (2020/01/04): AB-testrun of Stockfish 191225 finished. -4 Elo to Stockfish 191210."

Neghina position

I wonder what today's situation is for this 10-year old Neghina position (prison for Queen)
also seen in Eigenmann’s Der Brillante Schachzug 53

[d] 3k4/2pq3p/pp5R/4P3/P6P/2PN4/1PN3K1/8 w - - 0 1

Best move and win : Nd4
