Re: End of Era is there: SF is finally beaten!

Holy Crap! What a remarkable game by Lc0. It really looked like Houdini had a very dangerous initiative on the Queenside with 2 incredibly scary looking passed pawns, but then all of a sudden Lc0 disregards everything and does a rook lift and attacks on the Kingside!!! Looked like suicide, but it g...

Re: King and knight locked together

Another incredible position was reached in the following game, where Stockfish 10 played White on 6 cores i7 980X and AF125 on 2xGTX1060 with 15 minutes plus 1 second time control. Previously to 36.g3? Stockfish evaluation was 0.00 and AF125's 1.27, after g3 eval of Lc0 jumped to 4.32 because the p...

Re: Cfish in practice and question

Cfish should never lose on time. Adjust the Move Overhead parameter:

Move Overhead
Assume a time delay of x ms due to network and GUI overheads. This is useful to avoid losses on time in those cases.

Also, as Guenther notes, Contempt ranges from -100 to 100, with default 24.

Re: Did Leela miss a win in the KGA vs SF here?

After 24...Kb8, we have rk6/1pp4p/p3p3/2b1q3/8/2N4Q/PPP1N3/R4K2 w - - 1 25 Cfish-dev with MultiPV=2 and some forward/backward searching sees little for White, though it doesn't consider Leela's 25.

Re: LCO on Goldin versus Korzubov position

Atleast leela managed to squeeze the black king inside the white's queenside. Infiltrating with the king on the queenside was a major plan for black. Being able to infiltrate with the king on the queenside is a major progress for black i'll say. Unfortunately it was not enough in this game. Leela "...

Re: SF10 blunder??

anyone able to replicate this/explain the logic? SF just gives up a pawn in what both engines had evaluated as a drawish/drawn position with 43. Rc1... my CPU is currently occupied w/ the ongoing match so i'm curious if SF discovered the position was in fact completely lost. [d]8/1p1r1p2/1R2b3/P2p1...
