I liked the Round 11 win, where Rybka 4.1 gave up a piece for a couple pawns and decent compensation (move 14) -- but then Houdini 1.5a showed White's superiority by giving up two more pawns (moves 21-24).

Final standings:

Code: Select all

N Engine         Pts    SB     Houdini 1.5a  Rybka 4.1    

1 Houdini 1.5a  22.0  396.00                 + 9 = 26 - 5 
2 Rybka 4.1     18.0  396.00   + 5 = 26 - 9

After an exciting start where Rybka took an early lead Houdini
dominated the later part of the match and successfully defended
its TCEC Champion title.

See you all in season 3!

Great tournament..always nice to follow..hope to see season 3 soon!

Now i think we have to wait a while when we see a new version from these top engines.
So it's very possible we will see Rybka and Houdini in the Elite Match more times ,what is very exciting ofcourse.
It's just a idea,because you running a 980x system to let run Houdini with Splith Depth 12 in season 3 ,and i'am sure you gonne see
a better result!
Even you told me that you don't see a difference between default or with a different Splith Depth..so then i say you don't
loose anything to try it out with SD12

Everything is perfect for me..it's just a idea (tip) i give.

Regards,
JP.

I'm curious too: let me suggest a short delay before season 3...
Using the same opening sequence, play these games again, with this adjustment!
