[MMarco]

Wow. A model attack for the center game. I liked very much Be1 followed by the pawn storm on the kingside. Very nice sacrifices too from Leela to maintain the initiative. Impressive.

[M ANSARI]

Forget the attack ... since when did Lc0 start playing the endgame without trolling ???!!!! That was an efficient endgame play! Usually you had to turn red watching Lc0 play trolling moves in the endgame!

[Gejsi Marku]

Are you sure that isn't SF NNUE? Never in a million years would I imagine an endgame by Lc0 like that even with MLH
