Subject: Extensions and Futility Pruning

Author: James Robertson

Date: 17:51:00 05/04/99


Whenever my program makes an extension, say, at depth = 4 it finds it is in
check, it will not do any futility pruning/razoring for the rest of the branch.
I recently read that some programs will do pruning/razoring even if there is an
extension, unless it is at the current ply. Is this a better way to do things?
It seems like it would nullify some of the effects of extending, but it could
also save a tremendous amount of time too. What should I do?

Thanks for any help,
James
