I said "probably donated." If I knew exactly who, what, when... I would
have said so. As to why "probably," it is an elementary probablity
excercise. There are at least 10 top level programs. SSDF picked 4 to
test on the fastest hardware and these 4 happened to be CB programs.
What are the odds for this? If we assume 10 candidates (4 CB programs
and 6 non-CB programs) for the fastest machines there are 210 ways to
pick 4 out of 10. Only one pick will have all 4 from CB, hence the odds
for this are 1/210 approx 0.48 percent. If you had only 9 candidates
(with 4 CB, 5 non-CB), the odds are 1/126, i.e. 0.79 percent. With 8
candidates the odds are 1/70 i.e. 1.4 percent. Since we're dealing with
a pick which has a significant effect on the CB's financial gain, the
odds against the particular pick (99.5 percent) and the gain imply to
anyone with at least .48 percent of common sense still operational that
some funny things happened behind the scenes. Whether it is a free
hardware, paid travel to tournaments, or whatever else the creative
marketing gurus can think up of these days as an incentive to reviewers,
it is quite probable that some CB->SSDF incentive mechanism did exist.
It happens in every other business, why would chess software evaluation
be exempt from the laws of human nature and the laws of probability?

How far does an SSDF pick need to bend the odds before a
suspicion is not over the hill? Would 99.99 percent
against the odds, instead of 99.52 percent, be enough?
