Subject: Notion: shrunken bitboards

Since bishops can only touch 32 squares of a chess board, has anyone bothered to
write a system using 32 bit bitboards for bishops?  About like a rotated
bitboard, but shrunk by half.

Also, knights can only cover a 5x5 area (with only 8 spots attacked or defended)
and so it seems that knights might also use a compressed scheme (though not
nearly so obvious as bishops).
