Very often a new version of a chess program is
soon followed by another corrected/improved(?) version.
Sometimes the official name isn't changed and
sometimes it's called X.1 or something similar.
In SSDF we have usually upgraded to the new version,
but often the results of the older and newer programs
have been mixed and presented under the same name.
Sometimes we have time to restart the testing.
When Steen Suurballe provided a corrected version of
his program, we decided to stop testing Gandalf 5.0
after about 200 games, and instead played with
Gandalf 5.1 Athlon 1200 MHz. Now we have reached
595 tournament games, and it has a rating of 2646.
That is only four points more than v. 5.0 has. The
conclusion is that we cannot demonstrate any
difference between the strengths of the two program
versions.
Another new program is Fritz 7.0 (7.0.0.6) K6-2 450 MHz.
Whereas Fritz 7 on A1200 is 16 points above Deep Fritz,
on this slower hardware the situation is reversed. Fritz 7
has 21 points less than DF and has a rating of 2631.
We have played 124 games with the UCI-version of
Shredder 6.0 K6-2 450 MHz, using the opening book of
Sandro Necchi. So far the rating is 2630. With so few
games it's difficult to draw any conclusions concerning
which opening book Shredder 6.0 might benefit most from.
Fritz 7.0 A1200 is still leading, but has lost 18 points
since March 27. The two Tiger-versions have gained 8 and
12 points respectively. Shredder 6.0 has six points more,
Junior 7.0 nine more points and Shredder 5.32 has added
eight points.
We have now started to play with the Paderborn-version
of Shredder 6.0. When ChessBase sends us Hiarcs 8.0, we
will immediately start to test it.
Next list will appear in early July.
