Lc0's shortest win. Cfish did not have a clue either, exchanging queens into a maybe lost ending with only -0.18 =+ evaluation.
Cfish could not find a way to defend against black's unusual pawn mass after 23...gxf5, central doubled f-pawns connected on both sides.

Stockfish: 1 @ 2.0/2, 16 @ 1.5/2
Lc J94-60:             5 @ 1.5/2
4 @ same color won, 24 @ both draws


     Stockfish quickly crushed J94-60 with both colors in Round 17:

With 11...Bxb4 -0.09,  = or +=, J94-60 thought it was equal though behind the exchange and 2 pawns,
then Stockfish exchanged its queen for 2 knights to win! [Event "G/90''+1'' Ponder=ON Sy.6"]

Thanks again for your threads!

Really enjoy going through your game scores and notes when time permits. Reminds me of the old Chess Dragon threads on the old Immortal Forum.

Thank you! My personal philosophy is to go for at least some interest besides my own, so your thanks helps confirm that, much appreciated!
