As Bertil answered in the other reply to your post, one of the SSDF tester, who
just wanted at first to organize a tournament on slow computers, asked me for a
version of Tiger.

He tried my program and, apparently, found that it would be interesting to do
more "serious" testing with it, that is to include it on the SSDF list.

Unfortunately, all the SSDF guys who owned a 450MHz computer were very busy at
this time (they had to finish the tests of the 4 programs that are currently on
top of the list).

So the tester asked me if I agreed to have results of Tiger published for P90
only, and to have the name "Tiger" appear instead of an anonymous number.

I agreed, because I thought that tests on P90 only were better than nothing, and
I also thought I had nothing to lose.

That's how Tiger 11.8, which was originally provided to this tester to play in a
private tournament, made his way to the official SSDF list. :)

Unfortunately, I had no time to prepare a better version for them. That's why
they have tested v11.8, which is completely outdated by now, as it is the
version of April 99 (current version is 12.0).

Another problem I haven't been able to fix in time: this version has played with
the book that Shep and Didzis used in the beginning of their tournaments. It is
now well known (ask them) that this book was full of dubious lines...
