How so?

Issue #1: Program A has a feature that Program B does not (such as contempt or
maybe learning, or maybe a new search function that cuts out 30% more nodes). So
what? This never matters.

Issue #2: Program A has a feature that Program B also has, but it is turned on
in the tournaments for Program A and not for Program B. This has validity if you
are talking about features which are not defaults and which can also be turned
off and on by the operators. If Program A has the feature by default and Program
B does not, too bad.

This would seem to have been a major disadvantage to Nimzo in the tournaments
before the SSDF allowed programs to know who their opponents were (if there ever
was such a period of time). Although it is an advantage now, again, so what? The
programmers of Junior, Fritz, Rebel and others could have put such a feature in
if they deemed it necessary.

It is only unfair if you explicitly turn on a feature for one program that you
do not turn on for another. If it turns on by default, who cares? It's like any
other feature then (such as Alpha Beta).
