Unfortunately, no, I don't think so.
Why?
Well, because some people think that open source means “Feel free to steal any of these ideas”, and using it to help themselves make a big leap forward with their commercial products.
It has happened before and it will happen in the future.

I don't understand that chart. Why 1900 games for Stockfish but 100 for all others?
CCRL is still working, shows Stockfish trailing by Houdini 3 by a mere 4 elo or so.

What about other time controls?

The difference is that now...even if someone copy the ideas and close the code SF will surpass it in just a few days again. So...we are seeing a totally new paradigm arising .

Still stockfish will lead because is a different chess engine and not all the ideas will on others engines unless they test it but stockfish has biggest testing resources than other engines no doubt the Will be far ahead

the new stockfish is released!!

and included the two following super powerful engines in the tourney

* Stockfish 120913
* Gull 2.2 (Sep 11th or 12th)



after hundreds of matches
I'll post the full results and whole pgn match file!!!


***


dozens of matches are complete and

* Stockfish 120913 seems super powerful
(quite more powerful than the Stockfish 070913)

* Gull 2.2 (Sep 11th or 12th)
seems quite powerful (like 100 elo below stockfish)
(but only dozens of matches are done so
the current elo rating means very little and
the error level and elo fluctuation at this moment is very high
so these current results are very inaccurate
and should be taken with grain of salt) thumb up thumb up thumb up 


***


9 Stockfish 110913          : 3158  130 (+ 23,= 59,- 48), 40.4 %
Houdini 3 Pro w32             : 130 (+ 23,= 59,- 48), 40.4 %

I aborted the tourney for Stockfish 110913          
Stockfish 110913 seems buggy and weaker than the predecessors
after 130 matches
Stockfish 110913 had
23 wins and 48 losses

I wrote about this problem before, is the real threat?

Hi Kajordzak, I have the same problem with Norton. I wrote to the guys from Norton to check the site and files again, because no other antivirus scanning showed any problems with the files. They answer me the question were resolved, cause it was related to reputation W1, and they would include the site in the white list, but Norton is still deleting the files when downloaded. After that, I restored the exe files from quarentine and use the engine normally with no problems so far question

Fix time parameters for blitz games

The ideal setting for super-blitz might be something like:

"Emergency Base Time" = 50
"Emergency Move Time" = 5

This would give a total emergency time buffer of:

50 + 40 * 5 = 250 ms

This setup replaces the previous half cooked hack
"Don't blunder under extreme time pressure".

Test results are very good at super blitz, but keep good even
at 60 secs.

At 5+0.05
ELO: 24.30 +-2.4 (95%) LOS: 100.0%
