New Stockfish 5 to be released this weekend

[Alex54]

Stockfish 5 new version will be released this weekend, after crushing Komodo 7 in the TCEC Season 6 Superfinal ( 13-6 and 45 draws).
Now the problem goes to Komodo 7. In my opinion its now lonely author was not able to manage the releasing tempo, as he commercialized Komodo 7 BEFORE the starting of the Superfinal. He should have act as the Stockfish team, doing it AFTER the finishing of the Tourn.
Now his situation is rather difficult ,as it is not possible to justify the 60 dollars price of the Komodo 7, after such a disastrous result in the TCEC Superfinal, opposite to a FREE Stockfish.
Congratulations to the Stockfish team. They got an impressive Tourn, with a terrible and unexpected beating to Komodo, winner of the previous TCEC Season.

45 draws (70%) doesn't seem to constitute a "crush."

How sure you are that stockfish might be released this weekend huh ? did Marco Costalba say it or even announce it in public ?

Let's look at the results. I use gratefully a small cpp program, someone else posted here earlier:

$ ./elodiff 13 6 45
Number of games: 64
Winning fraction: 0.554688
Elo difference: +38.1534
LOS: 0.945853

LOS is calculated using the methods shown by remi coloum.
Thus it is quite certain that stockfish is better, _but_ LOS does not say how much better. It could by better by one Elo point with the same confidence, LOS simply does not know that.
The estimated Elo difference is 38, gathered with 64 tournament games.

They used a special book, to expose misevaluations and to avoid drawish positions and this suceeded obviously extrenly well. _But_ you should keep in mind that the Elo difference is exaggerated due to this.

My concept "crush" arises from the other point of view, in terms of percentages of win and lost games, MORE THAN DOUBLE.
THAT is a crush, at this level of playing strength, where the situation of the first programs an their playing levels is supposed to be most balanced and very , very equalized.
And as far as we can see after the Superfinal, this is NOT the case.

Don't know about this weekend, but here Marco wrote

I will release SF 5 in any case after TCEC, as already planned and announced.

I regard 13 wins to 6 as comprehensively beaten. But second place is no shame, Komodo is still a superb engine, and the Komodo team can be proud of their efforts.

Openings chosen for there entertainment value over there chess testing value. As was done in tcec. Will always favor the weaker engines. Not the other way around as you claim. Inferior openings always help the weaker engine win or draw games. When the openings are played by both programs from each side of the board. A weaker engine can win or draw games against a superior program just because of the inferior opening that that the superior program was forced to play. Resulting in a contraction of the true elo difference.

A special book to avoid drawish positions can help the stronger engine
because with random balanced openings part of the openings can be easy draw for the weak engines and you avoid it by the special book.

For the Superfinal, there was an attempt to find openings that were less drawish without favoring White or Black too much. These type of positions help differentiate the engines as well as creating more entertaining games. Obviously, the selection process was not a complete success, but I think it worked well. And I do not think the TCEC results underestimate the strength difference between Stockfish and Komodo. A random selection of openings typically used in engine testing would tend to have a higher draw rate and W - L would be lower IMO.
