Hello:

I prefer use the tactical exercises for human players that I can get in several
Chess Magazines or the Chess Informator. By this way, I can learn more about
tactics and the same time, you can test the chess programs by tactical theme.
Generally, the Chess Magazines classify the tactical positions by theme.

Apart of the symbolic calculated Elo of the Test Suites, the most of these don't
classify the tactical themes. I cannot conclude in advance if a Chess Program is
bad or good tactically using the most known Test Suites.

Why? Because you don't have any secure way to establish wihout objections in
which tactical themes the Chess Program is failing.

You need about forty positions (my own experience) by tactical theme, so you can
conclude with a good grade of certainty if the tested Chess Program is really
failing in a specific tactical theme.

Another consideration: you should only choose the tactical positions whose
solution variation has an unique tactical theme.

Bes Regards, Arturo.
