Well, not sure it is worth anything. But Take SafePath (where pawns can go
safely) and use that to calculate pawndomination. LEFTATT = (SafePath >> 9) &
~FILEA etc. You can use that to see if centre squares can be dominated, or to
see if you can potentially "break" the opponents pawnformation somewhere (if a
potential pawn attacks an opponent pawn at a square not potentially dominated by
the opponent). Again: not sure it is worth anything, just playing.
