I think it's just by chance. There are many suites, where Comet does'nt do very
well (e.g. lct2). So there should also be a few where it does well because the
program isn't that bad.

In order to reliably determine the playing strength of a program with the help
of positions, I believe that a very large set of positions (several hundreds) is
needed. It should be a mixture of tactical, positional and endgame positions
like lct2 but far larger.

On the other hand, the current well known suites are either too small or aren't
appropriate mixtures. Most of them are purely tactical. I'm afraid, that it's
very difficult to compose positions with a unique best move for only positional
reasons.

These suites measure only some special fraction of the program's playing
abilities. Kaufmann belongs to these.

By chance, kaufmann hits a fraction which is perhaps well done in Comet. But
don't ask me what this fraction is.
