Thank you!! This is great!

A big success for NNUE:

Sf-Classic_21021123_x64 @ 300 seconds: 11.Qa4+ +0.93/40 5589knps
Stockfish_21021123_x64 @ 120 seconds: 11.Nxe5 +0.48/34 2707knps

A possible improvement however after your game 16.Rac1 +0.50:
r3kr2/1p2q1pp/p2p1n2/8/2B1P3/2N1B2P/PP3PP1/2RR2K1 b q - 1 16
It looks like if 16...Rc8 17.Bb3 maybe is only +=, engine output at the bottom.
instead after 16...O-O-O in your game white's evaluation jumped up after 17.Ba7! +1.21.

I found one game at chesstempo.com, the same move order and
