D20 QGA: 3.e4: Stockfish's best both colors opening, best as white and 2nd best as black.

23.Be7!! was the only move to win.
26.Rh1!! sacrificing a bishop for a winning queen and rook f/g/h files attack.
29.e6!! can be captured 3 different ways but wins because black cannot defend the a1-h8 diagonal.

Hi
http://lczero.org/networks/

then 'Find on this page' or similar in your browser: 49921

Here is the link also: http://lczero.org/get_network?sha=4fd54df8e046a0e5c3b6aa1ddd1fde352f771eb9c5115298f6782dbb29785310
Good luck

P.S. 49921 the highest rated 49xxx run in "3" 2nd column (not the normal 1 for 6xxxx or 2 for 5xxxx) extended run for 4xxxx's.
Self-play rating 3355.
I noticed it was used at CCRL 40/4: https://ccrl.chessdom.com/ccrl/404/ .

(Before I noticed that I was using 42872, the most recent, Sept., of the "3" of 4xxxx's, rating 3351, looks highest of the 42xxx's.)
