If you don't think it is the case, why are you talking about it?

The marvelous thing about computer chess is that anybody can say anything about
any program. And it is hard to say if it is true or not, because verifying a
proposition can take more than a week or a month of test games.

In the case of Chess Tiger, what I can say is that version 11.5 would beat 11.2
at any time controls, given a sufficient amount of games. This has been tested
before version 11.5 was shipped to testers. This kind of test is always done
before I send a new version. This is the least I can do, so testers don't loose
their time with an obviously bad version.
