After a little bit ( 5 Min) of probing their HTML code, I found a temp solution to the problem. :D

Grab it from here: https://newman.chess.com/games.pgn

PS:

Pro Tip: If you use the non secure version of the link http://newman.chess.com/games.pgn it will also work in Hiarcs Chess Explorer and you can then use your favorite engine to analyze the current game while it is in progress.
If someone is interested...
Stripped off the PV and added a round number in nice looking column style (example below)
Unterminated games included! (Games 1-59 +5* unterminated)


Code: Select all

1. e4 {+0.27/30 70}
1... e5 {-0.15/29 62}
2. Nf3 {+0.27/29 1}
2... Nc6 {-0.29/27 63}
3. Bc4 {+0.27/29 1}
3... Bc5 {-0.27/28 58}
4. d3 {+0.28/27 31}
4... Nf6 {-0.23/27 23}
5. c3 {+0.28/27 28}
5... a5 {-0.25/27 124}
6. O-O {+0.28/27 0}
6... d6 {-0.22/27 69}

Against the LS0, the engines have almost 2x-acceleration due to the combination of HT and Ponder.

Ethereal have ~55 mnps vs Stockfish and ~90 mnps vs Lc0:

I was not surprised here. Most others saw it coming too. Kingscrusher is sure to do a video on this game.

This is the Semi-Slav, Anti-Meran, Lilienthal Variation (https://www.365chess.com/eco/D44_Queen% ... _variation). It's amazing they came up with all this on their own. According to my admittedly outdated database, the first new move was 18.h4, where previously Bxh6 had been played in a 2013 ICCF game which was ultimately drawn.

In September 3, 2018, chess.com will be hosting their computer chess championship for this year. There are a lot of background factors that favor Leela to be able to fight for No 1 vs the best AB engine , Stockfish. Of course, if you recently saw Leela performance in TCEC Division 3, this post will be a big joke( But in bonus games, she draw all 9 games vs Stockfish 8 and Ethereal).

Improvement factors/favoring factors for Leela,

1. 4x V 100 for Leela vs 48 cores ( GPU/CPU ratio will be 3.6 times in favor for Leela than TCEC, approximately + 90 elo)
2. Newer ID are already stronger than 520 (at least +50 elo)
3. Leela will have Tablebase support (possibly +20 elo)

As latest version of stockfish is only 100 elo stronger than stockfish 8, Leela will be in more favour if she can effectively use 4x V100 and Tablebases.

As expected/predicted, she is doing so far so good.

Currently in top 3, fighting for no 1, of course.🤗😅

lc0-SF will end in a draw.
SF has shown 0.00 from move 24.
Now move 140.

Maybe adjudication has some merits. :wink: At least the time control is short.

To me this looks like 15-25% when going from 2 to 4xV100.
And going from 1 to 2 V100 ?

Can someone tell me, does anything need to be changed in the setup of Lc0 to run on two graphics cards or does it recognise them automatically?

With the new Nvidia crop on the way I'm wondering if two cheaper cards may be faster.

Add this to a command line:

Code: Select all

--backend=multiplexing "--backend-opts=(backend=cudnn,gpu=0),(backend=cudnn,gpu=1)"
