Humans taking the test using the full time allowed for 376 positions (about_75_hours_over_time ... not all at once!) scoring perfectly would achieve 2200 IQ elo. Writing down their solutiions comparing variations with the book's answers, etc. Scoring partial points ... Keeping track, if they use less time than an average of 12 minutes per position bonus points are scored. I extrapolated the table in the book to max out these bonus points as engines are such fast calculators. The idea is *not* for humans to take this 10 second test. That would be ridiculous. Humans should use 12 minutes per position and justify their answers ... By looking at engine output, move chosen, evaluation, you will know if an engine "understands" the position or not. The test than generates an IQ tactical rating only. Strategical factors, and endgame knowledge are not considered in the test and are in no way measured. The ratings don't compare to "real" rating lists. It's just for fun, not too serious. In my preliminary testing with winboard engines it seems to be internally consistent. The stronger ones score higher and weaker ones lower of course. It's all kind of interesting .... Jim
