Subject: Ruffian's Secret?

Author: Steve Maughan

The latest info about Ruffian states:

"Mobility is based on precalculated tables that can recognize special patterns;
this is one of the major evaluation terms"

This is interesting.  How can you precalculate mobility?  Maybe using rotated
bitboards - but from the interview with Per-Ola he states that the structure in
Ruffian is:

"Today I use a hybrid between bitboard and 8x8"

Clearly Per-Ola considers this one of the strengths of Ruffian.  Does anyone
have any ideas as to what he's doing that may be different?

Regards,

Steve
