Polyglot opening book specification

[matematiko]

Well I don't if I was the one that started stiring this controversy about zero weight moves (probably not)... the thing is that the newest polyglot version 1.4w20 ignores them.

To whom it might the credit is deserved....thank you.

Cheers,

After reading this http://www.talkchess.com/forum/viewtopic.php?topic_view=threads&p=258564&t=26809,I decided to update pg.
Zero weight moves seem a usefull extension.(Just like a non-crashing polyglot )
But as long as scid does not really set the weight to zero (it sets to 1,the lowest value),it is a bit academic.

I have a question.

After clicking the new "add" buton, the posible selectable moves displayed, are they all the possible legal moves? Or just the possible moves that were "unreachable" before, based in the pgn database used to create the book?

Thanks,

Scid did the closest thing to zero weight permitted by the spec (as indicated by ASSERTS in the PG source).

Could someone post a small snippet of the source around the area where the zero causes problems?
