H4 or S5 !?

[Vinvin]

I think 4pc Syzygy will change nothing in the SF strength. So for me, it's a second test with SF at the exact same level, which it is interesting too

BTW, it should be interesting to find one (yes, only one ! ) game where the 4pc Syzygy change the final outcome.

I am not sure either, but I doubt a significant win with 5pc as well.

Again, I hve no doubt that for a serious analysis of games/engamepostions the use a Tablebases is VERY usefull.

Time will tell, right now, after 50%+ it looks like a small 1 digit elo gain (3-5)

Hello Miguel:

So, the reason for the discrepancy in the ranking order is exactly that: BE counts the draws twice, Ordo once.

Miguel

The following thread is probably related to that:

1 draw=1 win + 1 loss (always!)

It is a little long but worthwhile.

Regards from Spain.

I think an individual comparision is missleading. You compare two sets of games with just 220 games each. The possible error is huge and even an identical run might be that much different.

Overall S5 with 4pc SYZ was better by 0.89% - but even that is within the error bar.

Anyhow, I will play the missing games vs DF14 and will check if I replace SF5 standard with this one ...

Here's the main question : is the 0.89% difference due to the settings or due to statistical error ? For me, it's due 100% to statistical error. The other mean is the 4 pcs EGTB add not even a fraction of rating point to SF ...

Do you know a method to answer this? I don't! Personaly I think it might be just statistical noise but even if it is due to the bases it is so small it can be neglected.

But for me the main point is the oportunity to come out of the "statisticcal dilema". I do not have (the VERY VERY RARE) missmatch between Bayes/Elostat/and Ordo anymore

4 pc EGTB should at least lead to playing queen vs. rook optimally. I don't know how often that occurs. My best guess is that it's worth about 2 elo. There may be some rare cases of other endgames, maybe rook vs knight or rook vs bishop, where it could make a difference. It helps to know which cases of those endings are won and which are drawn.

Do you "know" or do you "suppose" that SF without EGBT makes inferior results in the QvsR endgames ?

[Vinvin]

I just checked, 3 games SF without EGTB win the longest checkmate 3 times in a row against SF with EGTB.
In a very fast time control : 10sec+0.1sec !!

Overall S5 with 4pc SYZ was better by 0.89% - but even that is within the error bar.

Here's the main question : is the 0.89% difference due to the settings or due to statistical error ? For me, it's due 100% to statistical error. The other mean is the 4 pcs EGTB add not even a fraction of rating point to SF ...

4 pc EGTB should at least lead to playing queen vs. rook optimally. I don't know how often that occurs. My best guess is that it's worth about 2 elo. There may be some rare cases of other endgames, maybe rook vs knight or rook vs bishop, where it could make a difference. It helps to know which cases of those endings are won and which are drawn.

Do you "know" or do you "suppose" that SF without EGBT makes inferior results in the QvsR endgames ?

I do not understand how do you know?

People talk only about advantage of playing the endgame perfectly
but it is not the only advantage and there are at least 2 different advantage by tablebases.

1)Knowing positions not to go.

Stockfish's static evaluation is wrong for some tablebases position and stockfish may fail by going into them when the problem is not playing the position perfectly but not to go to them.

Stockfish without tablebases may go to the following position with white only to discover too late that it is a draw

[d]k7/2Q5/8/8/8/8/7K/6r1 b - - 5 1

The fact that it can see at depth above 20 that it is a draw is not going to help it if the remaining depth in this position is only 10 plies.

2)Playing faster.
Stockfish can save time by not searching some tablebase positions so the advantage can be simply that it is going one ply deeper in the relevant lines that do not lead to 4 tablebases piece positions.

I suppose. But even if SF wins the queen side without TBs, it may defend the losing side better with them, which may pay off against opponents without TBs. Also, as Uri points out, it saves time whenever this (or other) endgames arise during the search.
