new test positions

Post by jdart »

I have posted some test positions I have collected recently here:

http://www.arasanchess.org/newtests.shtml

some were mentioned in this forum. Quite a few are from recent tournaments or from Arasan games, on- and offline.

Jon thanks for new positions.
Would you check the download link, it seems it is broken.
Maybe it has only one test position for download.

thanks

Maybe Jon has taken the file offline again? I can't download now but could download it yesterday, there are 25 positions in all.

Eelco,
Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

At the moment no problem to download. I run suite with 4 engines and
Fritz 10 was the best ahead of Rybka 3!

Ok, sorry, I was looking at #25. You are right, #23 looks broken.

Re: new test positions

Post by Eelco de Groot »

Here is a possible substitute testposition :) , from a testgame against Rybka, Blueberry maybe could have lasted longer if it had played the better defensive move 27...Re8 instead of 27...Rd7. Rybka finds it fast enough but Blueberry not yet at least not for the timecontrol used below.

3r1k2/p5pp/n1NP1p2/1NbB1b2/5P2/1P6/5P1P/5RK1 b - - bm Re8; id "critical defence 001 am 27...Rd7"; c0 "Rybka 2.2n2-Blueberry Beta4 Build 375 10-03-2009";

No fireworks here I agree but this type of position is where Rybka is just stronger than most competitors -although I should say have not checked other programs here in this position-, she makes less mistakes because of her much better 'scout searches' as Vas calls it :) .

This was the game:

[Event "12 Minutes/Game + 6 Seconds/Move"]
[Site "Engine Match"]
[Date "2009.03.10"]
[Round "1"]
[White "Rybka 2.2n2 mp 32-bit PVtips5menbases"]
[Black "Blueberry Beta 4 DM70"]
[Result "1-0"]
[ECO "A60 - Benoni Defence"]

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
