Stockfish 7 Revisited: No superiority after first round

As mentioned in a previous post, i'm currently running a relatively longer tournament between different Stockfish 7 builds in order to find out, if there's such difference, which build is better.

I must admit i won't be surprised if thousands of games reveal nothing precise. Maybe there's nothing to find.

After 1000 games played, there's no clear sign of superiority between 3 builds of Stockfish 7. Even the gap between Komodo 9.3 and Stockfish 6 doesn't tell too much.

That needs more and more games. Therefore, there will be more and more games!

The standings after playing first 50 openings of TCEC-7:

1) Stockfish 7 JA        230.0 / 400
2) Stockfish 7 DF1.60    220.0 / 400
3) Stockfish 7b2 JA      218.5 / 400
4) Stockfish 6           170.5 / 400
5) Komodo 9.3            161.0 / 400

  1. Komodo 9.3 по умолчанию настроен на контроль 120+1,при контроле 300+1 в настройках komodo,следует уменьшить selectivity до показателя 117,я проводил тестирование komodo 9.3,при контроле 300+2 он stockfish 6 уверенно обыгрывает.Настройки нужно оставить default,а показатель selectivity плавно уменьшать с увеличением времени на партию.Нужно вывести кривую на графике для этого показателя.

  3. @ Alexey: Ok maybe... but my rule is to use default settings except threads and hash. I don't wanna tweak Komodo and do nothing with Stockfish. It would not be fair.
