IE I bet you would *not* beat it twice with the same opening... so I don't know where the above came from. nor do I know what it means or what it has to do with counting doubles or not counting doubles. Remember, you cut the match off after one game. So there could not possibly be a double... > >>"doubles" are something that a good program avoids if it is >>losing those games, > >Fixed in Rebel9. > >Still I believe SSDF should not count doubles. > >The goal of SSDF is to test the playing strength of a chess program >and not smart book algorithms. > >- Ed Schroder - I believe the purpose is different... To compare the programs to each other in the same methodology that a human would have to use to play the program. IE humans tend to play the same opening and it will be up to a program to take evasive action if the human finds a way to get to it in an opening variation. I've seen my share of gripes about this very problem, when programs (mine included until about 1.5 years ago) would play the same losing opening over and over... A program that won't fall for this tactic doesn't have to worry about whether doubles will be counted or not, except for winning doubles that it will find if the opponent doesn't know how to vary...
