Interesting but ...

1. Why is rybka 32 bits used under winXP64 instead of the much stronger rybka 64
?
2. Why is rybka used without its own J Noomen book ?
3. (Do questions 1. and 2. mean that the tester used a pirated copy of Rybka?).
  ...this one is not really a question ... :-)
4. Should private tests of unavailable private versions be publicly commented
without anybody but a few selected persons having the opportunity to assess and
control the results ?
5. Toga 1.2 beta2 has new adjustable parameters : what were the values used for
the test ?
6. 60 blitz games is evidently a much too small test for claiming any evidence.
I heard of other tests running with an already much larger number of games where
Toga 1.2b2 is being crushed by Rybka 32 bits. I suppose this is precisely the
reason why Thomas Gaksch did not made this beta version public yet.

So let's wait a little bit.
