Stockfish loses the first game by a gross positional error that most patzers would see! Trapped its own rook! And a brilliant conversion by Lc0!

Posts : 880 Join date : 2020-11-25 Location : USA

Stockfish Strikes back! The match is even.

Stockfish is 385x faster then Lc0 in NPS, And Stockfish is out searching Lc0 by 55 plies per move average to 10.9 plies average per move for Lc0.

Lc0 only advantage is Lc0 has a much smarter Neural Network.

Match now +1 -1 =54

Game 55

One misstep at move 70..g5? cost Lc0 the game. It took Lc0 about 1 minute to see that 70..g5 was an error on my RTX 3070.

And Stockfish only needs 5 seconds to see that 70..g5 is no good!
