Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

And the funniest joke here is the claim stockfish is within 200 Elo of perfect play. And here is what is funny. Since Stockfish 12, the newest Stockfish has gained over 30 Elo. At this rate Stockfish 14 will play perfect chess! :shock: Stockfish 12 didn't gain 200 ELO over the previous version play...

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

But still, ALL engines are losing games. Only at fast time controls AND/OR from dodgy openings. Does SF loses a game in Berlin, Ragozin or 1...e5 English mainline at long time controls on decent hardware? If so it should be easy to demonstrate, I am yet to see such game. Here's Stockfish demonstrat...

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

Here is evidence that with a very drawish opening (1.b4) a very strong program (LC0 with two 2080 Super GPUs) can lose at long time control on powerful hardware: Leela thinks 1.b4 gives advantage for black at around 53.5%. This is close to equivalent of playing black from starting position. Additio...

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

Maybe it's 200 points away, maybe 400. We just don't know. The trick is going to be to select openings that are very close to losing - either drawn but difficult to hold or won but difficult to convert. TCEC is going into that direction and I feel it will be more than 200 ELO vs godlike engine from ...

A beautiful position from a real opening

I am not sure if it's known. I came across this position analysing one of my blitz games: r1bq1rk1/p4ppp/1pnbp3/3p4/3P1B2/2PBPN2/P4PPP/R2QR1K1 w - - 0 12 And now a series of sacrifices follows: 12.Bxh7+ Kxh7 13.Ng5+ Kg6 14.Qg4 Bxf4 15.exf4 f5 16.Qg3 Kf6 17.c4! dxc4 18.d5! exd5 to arrive at: r1bq1r2/...

Re: Question about mate scores Lc0 vs SF

By "sees mate" I mean exactly that: forced reduction to TBs and being and to infer upper bound for number of moves. Both engines have access to the same tablebases so SF should see such reduction pretty quickly as well. I am wondering how it's possible for slow MCTS to see forced reduction faster th...

Question about mate scores Lc0 vs SF

Consider this position: 8/8/8/1p2K3/1P6/n5k1/6p1/6N1 b - - 3 60 SF: 3970x, 64GB hash, 48 threads lc0: 3080, 2000000 NN cache size Both engines with 6man Syzygy tablebases. When I run lc0 (J92-290) it instantly shows mate scores, mate in 143 to be precise. When I run SF (build from 14.10.2020) it sho...

Re: Why does TCEC use unbalanced opening?

Alright stockfish 12 is very good and two different entity in LTC produce very likely a draw. But would you make the same bet using stockfish 12 against the best engine of 10 years engine from now? We will say that the chess is nearly solved when there is no more progress, Imagine having to play th...

Re: Why does TCEC use unbalanced opening?

Do you want the best quality chess, or just artificial entertainment? Best quality chess from positions that matter. Balanced positions don't matter anymore as they are too easily drawn by current engines on current hardware. I would love someone to prove me wrong on this. I am willing to offer 100...

Re: 87% of the poll voted that SF will win Tcec Sufi 19.

Chess stats is a game of odds. And I know SF, and Lc0 better then most. So I was one of the 87% under these playing conditions. But this is not true chess, or testing. But a match of who can play garbage openings better. It seems to me that those engines are so strong that we can test one of the tw...
