Go up one level in this thread


I believe there are a lot of pruning techniques that are used in
commercial software but are not made public.

For example, Ed Schroeder has been able to achieve quite low node
counts per ply depth in Rebel. He's talked a little about what he
does, but it's still mysterious (at least to me). It is not just
null move.
