Evidently, it's a form of entertainment many people enjoy, but it's not chess as it's usually played, and it's doubtful that any interesting conclusions can be made from the match results.nabildanial wrote: ↑Tue Oct 13, 2020 4:41 pmIt has been the case since forever, it's not only for these past 2 seasons. I've heard the same exact argument from the losing side, whether it's SF, Komodo, Leela or Houdini fans. Same ol' story.

Some seem to want to see in 95+ games out of 100 that Chess is a bloody draw.

Yes! True chess engine testing is hard, and like watching paint draw. And correct, when 2 4000+ Elo equally matched players play. The result should be very very close.

The score right after book end is no verdict. Usually you need to look also at the eval several plies later to get a real clueDaniel Shawul wrote: ↑Tue Oct 13, 2020 4:51 pmI am surprized you need clarification for this but here it goes.jorose wrote: ↑Tue Oct 13, 2020 4:23 pmCould you clarify what you mean by this?Daniel Shawul wrote: ↑Tue Oct 13, 2020 3:59 pm It has been clear for sometime now that the unbalanced book is very unfair to Lc0.
TCEC does it for the sake of entertainment, but drawing any conclusions from it doesn't make any sense.
This SuFi and last one have been all about who can convert better given a position with a +1 advantage.
If every season is going to be like this, I guess there is no point watching TCEC SuFi.
I just took a look at the first 10 openings (20 games) and I don't think they are particularly unbalanced. In fact, I play several of those openings myself. The only ones I find somewhat odd are the French with Ng8 and KGA with Nc3.
Most of the lines are theoretically very well established and see a decent amount of play.I'm not sure where this notion comes from that TCEC has unbalanced openings this season in particular.
I also don't know what such fans want to see, would they prefer even less decisive games?
These are scores of stockfish right out of book for the second half of the match starting from game 52
SF may well be superior to Lc0 but this unbalanced openings prove nothing.Code: Select all
52 - +1.31 54 - +1.06 => 10. 1.06 17. 0.69 56 - +1.19 58 - +0.80 => 1/2-1/2 60 - +1.14 => 7. 1.14 139. 0.62 62 - +1.17 => 1/2-1/2 64 - +1.17 => 1/2-1/2 66 - +1.12 => 1/2-1/2 68 - +1.20 70 - +0.80 => 1/2-1/2 72 - -0.93 => 1/2-1/2 74 - +0.70 ?? here I disagree ;-) and would give >1.00 76 - +0.66 ?? 25. 0.24 78 - +1.38 80 - +1.05 82 - +0.83 => 1/2-1/2
Even SF without NNUE was able to get +7 over leela last season entirely due to the book.
about an opening.
Even at this tc and with the hardware of TCEC the first move out of book/start position might be evaluated relatively wrong.
I added the result in case it still was a draw. For the others I added much lower later evals if existed
(move number out of book + score, move number with later lower score,
but first move number not given for score <= 0.70 don't consider this as unbalanced)
Here are just two counter examples which prove this, game 60 and 76 from your list above.
Also look at all the drawn ones listed above, despite the 'virtual' advantage dreamed by SF.

All games ran through a macro to get clean readable pgn, last number is TL (time left).
Graphs copied out of Tom McBurneys wonderful game analyzer.

Re: 87% of the poll voted that SF will win Tcec Sufi 19.
When engines get better and better then draw rate should increase every season. As chess is draw.
Lc0 is put into tactical positions it wouldn't go itself. A little bit unfair. I think it would be better to give both own books and let them play itself. I haven't watched any (I'm too busy) TCEC so I don't how the games have been like. 100 games is a bit too little. But 100 draws isn't good entertainment.![Very Happy :D](./images/smilies/icon_biggrin.gif)

You are correct that some bad position can be held. But that is not the point! Why are bad positions being played at all.Guenther wrote: ↑Tue Oct 13, 2020 6:45 pmThe score right after book end is no verdict.

TCEC does it for the sake of entertainment, but drawing any conclusions from it doesn't make any sense.
This SuFi and last one have been all about who can convert better given a position with a +1 advantage.
If every season is going to be like this, I guess there is no point watching TCEC SuFi.
I just took a look at the first 10 openings (20 games) and I don't think they are particularly unbalanced. In fact, I play several of those openings myself. The only ones I find somewhat odd are the French with Ng8 and KGA with Nc3.
Most of the lines are theoretically very well established and see a decent amount of play.I'm not sure where this notion comes from that TCEC has unbalanced openings this season in particular.
I also don't know what such fans want to see, would they prefer even less decisive games?
These are scores of stockfish right out of book for the second half of the match starting from game 52
SF may well be superior to Lc0 but this unbalanced openings prove nothing.Code: Select all
52 - +1.31 54 - +1.06 => 10. 1.06 17. 0.69 56 - +1.19 58 - +0.80 => 1/2-1/2 60 - +1.14 => 7. 1.14 139. 0.62 62 - +1.17 => 1/2-1/2 64 - +1.17 => 1/2-1/2 66 - +1.12 => 1/2-1/2 68 - +1.20 70 - +0.80 => 1/2-1/2 72 - -0.93 => 1/2-1/2 74 - +0.70 ?? here I disagree ;-) and would give >1.00 76 - +0.66 ?? 25. 0.24 78 - +1.38 80 - +1.05 82 - +0.83 => 1/2-1/2
Even SF without NNUE was able to get +7 over leela last season entirely due to the book.
about an opening.
Even at this tc and with the hardware of TCEC the first move out of book/start position might be evaluated relatively wrong.
I added the result in case it still was a draw. For the others I added much lower later evals if existed
(move number out of book + score, move number with later lower score,
but first move number not given for score <= 0.70 don't consider this as unbalanced)
Here are just two counter examples which prove this, game 60 and 76 from your list above.
Also look at all the drawn ones listed above, despite the 'virtual' advantage dreamed by SF.

I will take TCEC words....from TCEC
Q: What do you mean when you say you “bias” openings, and why do you do it?
A: Bias is the degree to which a particular opening, or a set of openings, seem to favor one side or the other according to empirical data (historical outcomes) and evaluative data (deep analysis from top engines).
The opening position typically offers white a slightly favorable evaluation of +0.15 to +0.20 on traditional chess programs where the “comtempt” setting is neutralized. Low or zero bias in an opening book makes little difference in a tournament where time controls are shorter and contestants have a higher range of Elos. In that case, there will be ample decisive games.
However, if very strong, closely matched programs are playing at long time controls with no bias that invites a draw-rate approaching 90%. To combat this, we introduce bias in League 1 and to an even greater degree in Premier League and the Superfinal. In the latter two, you will see some openings where one color has no realistic winning chances and the game is all about successfully holding a draw from an almost desperate position.
"Note that both Nelson and Jeroen freely acknowledge that few traditional and neural net engines would find themselves in most TCEC opening positions of their own accord. This is deliberate. The whole point is to force engines to play unexpected positions and demonstrate their strength in all kinds of game situations. This is especially true for neural nets, which in training tend to emphasize favorite lines and neglect what they deem to be inferior ones."

Moreover, Leela can be trained to play unbalanced or weird openings. And then the issue with always playing sound balanced openings is that Lc0 acts similarly to an opening book of sound openings, this question being raised since the appearance of DeepMind paper. SF should probably be allowed to use an opening book in this case.

Re: 87% of the poll voted that SF will win Tcec Sufi 19.
I do think Daniel Shawul has a point.
One might argue (and, indeed, I have) that since both sides must play the exact same lopsided opening from the disadvantaged and advantaged point of view it should be a wash. If I have a dominant position and win, next time, the opponent has the same dominant position and I should lose.
However, the clear strength of LC0 is in very quiet positions. If we start from a lopsided position, this does seem like a penalty on LC0 because of how it plays.
As further evidence of this disparity, SF abandons NN technology when the score becomes lopsided.
Food for thought.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: 87% of the poll voted that SF will win Tcec Sufi 19.
Why would you do this, and if done. It would not be true chess. Chess starts with a unbias starting position. All moves matter in chess. And most importantly in the opening.Laskos wrote: ↑Tue Oct 13, 2020 7:04 pm Moreover, Leela can be trained to play unbalanced or weird openings.

This is why true engine testing is not done with garbage openings.

It seems you did not read my post, or did not understand it, or both (there was no time to read all of it anyway before your reply).
Still you had to do a full quote...
Not all positions given by Daniel above were 'bad', but just falsely evaluated as 'bad' (some were even <= 0.70).
