I understand the Nunn test as a "engine without opening library" test : it's a try to compare relative strength of engines. I think it's a good point to evaluate "pure" strength. That's not the direction I thought. The idea is to look at the way programs deal with different openings : some are complex, others positional or strategic, and, for the games I looked at, different programs have completly different evals for these positions. Besides it would be interesting, for me (am I alone in the case ?) to know which programs play better (understand better ?) the King's gambit, the Schliemann gambit of the Ruy Lopez or the Fajarowicz gambit. Other may be interested in the Sicilian Dragon or the Giucco Piano. I'm sure we would find great difference between programs of a generally same strength. I read once (was it you ?) that the French is a bad opening choice for computers : maybe could we find one that has better results than others with this defense ? Jeff
