This is a tactical test suite but the positions are not known.
The last fact is important because when the positions are known
programmers may be influenced by the positions in implementing tactical
knowledge.

Enrique found that in most of the cases result in his secret tactical test suite
gave good prediction for the results in the ssdf list.

I guess that the reason is that in most of the cases rhere are no big difference
in positional strength between programs and the program that is better in
tactics is also the better program.

It means that he will give it a lot of positions to solve and use the times of
the solutions to calculate a score for it.
