[Bug-gnubg] blowfish dll vs gnubg

[maareyes]

 

Hi,

 

I recently played this 9 pt match using the offline gnubg player on my FIBS client 3DFiBs. It is using gnubg.dll from Mike Rudman's Blowfish program. It was set at 1 ply for checker play and 0-ply cube action and the default settings of 8 candidates, .160 tolerance and no noise.

 

I analyzed the match with the current GnuBG for Windows from Oystein's site with the same settings of 1 ply and it flagged very many errors for the bot and give it a beginner rating. (this is unusual because it consistantly rates ET or world class)

 

I ran the analysis again with 2 ply and the bot is now rated world class

 

I found this to be rather confusing. How can a player using Blowfish DLL (based on gnubg) at 1 ply make moves that 1 ply analyzer does not agree with but 2 ply rates world Class.

 

 

I am using pretty much all default settings

8 candidates, .160 tolerance.. no noise

 

 

I still trust the anlayzer more than the Blowfish dll since it has made many errors that were obvious and that the analyzer flagged but in this case, 2 ply seems to agree with Blowfish dll. Is this just an isolated freak case?

 

Anyway,, they are all ET or close most of the time so for any practical applications, they are just fine.. just wondering what happened here.. thats all
