Just a few games I set up manually to watch.
Lc0.25.1-Blas (cpu) vs. Ethereal 12.21
G/3'+1" no Syzygy | 2700X
Net: https://www.comp.nus.edu.sg/~sergio-v/new/

After 26.Ne5 Lc0-Blas had already erred (Stockfish 26...Qb7 white +0.72)
r5k1/2p2pp1/ppqP3p/2b1N3/4n3/1Q4P1/PP2R1KP/2B5 b - - 2 26
26...Qe8? 27.Rxe4, but then white allowed too much counter-play and too many exchanges:
in the game below after Lc0-Blas's 43...h5! it gave itself -0.08 = seeing it was going to exchange white's last pawn,
and it stayed near zero until after its ??, Ethereal stayed with about 3.00+ for the bishop - both no Sy.

After 79.Bd4 (Stockfish Sy.6 says 79...Re2 0.00 =, saving the g-pawn) 
8/5kp1/8/1R3K2/3B4/8/6r1/8 b - - 54 79
79...Rd2!? 80.Rb7+ but Sf Sy.6 still says 0.00 = for the R+B vs. R.

After 110.Kd5 +4.23 (Stockfish Sy.6 110...Rc1 or ...Re2 0.00 =)
3k4/7R/3B4/3K4/8/8/8/4r3 b - - 58 110
Lc0-Blas played 110...Ke8?? -0.13 111.Be5 Mate in 43 Ethereal said in the fast blitz without Syzygy!

A nice ending by Ethereal I thought, though black might have had a chance with a better 48th move. [Event "G/3'+1'' no Syzygy"]

Vienna Gambit Accepted
