Re: Convert .obk books to .abk books?

There is an OBK2PGN utility, and then the PGN can be imported into ABK format from within Arena. http://homepages.paradise.net.nz/npattins/ChessOpeningBookPage.html I am not aware of a utility that converts directly to ABK format. Thanks for the info and link. Looks ideal for a few books but a lot ...

I'm not a good player so how do i determine what is a "good sac" or a "bad sac"? Is there an engine that can answer this question? :P

Don't know yet, but i'll test it when time permits.

EDIT: Do you know of a good "avoid sac" test suite? :)

This is just too deep for any engine on my hardware. What about on fast hardware?
