Re: LC0 bad search and poor tactics

I have done analysis on some of the 50 games and will post something on it. I think many will find it interesting. No doubt Lc0 is an extremely strong engine, but even more than that ... there is no doubt that it will become much stronger very quickly. At the moment it is still not a useful stand a...

Continuation after Kf1? Bxf2!

fwiw, i find t40 passing all of these (these being the 3 starkest blunders i've found so far) & avoiding a couple other, less-losing moves i've tested, but have only analyzed the Kf1 blunder at several MNs. 1r1q1rk1/p1pbbp2/7p/8/2PPnP2/1P6/PB2B2p/RN1Q1R1K w - - 0 20 31 [bm Qd3 (??)] 20.

Re: LC0 bad search and poor tactics

I just did a 50 game match with SF latest Dev against Lc0 and although Lc0 won that match easily (+90 ELO), I can easily point to many one move howlers. I mean where a position would move from +5 for Lc0 (totally winning agreed by both sides) to -5 in one move. Now of course you could say a 3 min a...

Re: LCO on Goldin versus Korzubov position

It seems leela is showing big progress for black in this locked endgame previously presumed as draw. 6k1/pp3p2/6p1/3p4/2pN4/P1P2P1P/1P1qR1P1/6K1 b - - 0 1 Analysis by Lc0 v0.20.1: 1...Qf4 2.Kf2 Qh4+ 3.Kg1 Qg3 4.Re7 b6 5.Re2 Kf8 6.Kf1 a6 7.Kg1 Qf4 8.Kf2 Qh4+ 9.Kg1 b5 10.Kf1 Qf4 11.Kf2 Qh4+ Black is ...

MCTS in Avengers' Infinity War

Didn't know Dr. Strange did an MCTS to win against Thanos too. https://www.youtube.com/watch?v=eGKPfZTXHsc Ok, Avengers lost in Infinity War - Part 1 but they would probably win in Part 2. Sorry, not computer chess related but it would be cool if humans can build an engine which can also choose the ...

Re: LCZero FAQ is missing one important fact

Why are just GPUs fast with NN engines? Please explain it to me! Before AlphaZero even came out including its paper, there was already a thread here by someone asking about harnessing GPU power because this expensive piece of hardware was just uselessly sitting down inside our machines during that ...
