In order to reduce threads like 'this opening position is lost! no it's not! yes
it is! it's lost when you use bitboards! but fisher would win this position vs
DB!' it would be good to 'formalize' won/lost positions after the opening.
You could declare an opening won/lost if one of the engines evaluates its first
move out of book with a score outside a predefined score-window [X, Y]. ([-0.5,
+0.5] could be an example) Some points:
- I intentionally used two variables so it's possible to have an assymetric
window (no clue whether that could be helpful or not)
- You don't capture positions where a human being with comp-chess knowledge
knows, that one engine _will_ lose but the scores of the engines won't catch it
- the scores for this score-window have to be adjusted (+1 should mean approx 1
pawn advantage)
- everything else I forgot :)
Ideas? Comments? Shrieking epitaphs?

PS. It's funny - we often claim that "{small number} games are not enough!" but
now we still make this experiment ;)
