I was just trawling through the sources of cyclone when I found something that might be of use:

Code:

const int KnightOutpost[2][64] =
   {
// these are probably white
     0,    0,  0,  0,  0,  0,  0,  0,
     0,    0,  0,  0,  0,  0,  0,  0,
     2,    2,  5,  5,  5,  5,  2,  2,
     3,    3,  6, 10, 10,  6,  3,  3,
     3,    4,  7, 10, 10,  7,  4,  3,
     3,    5,  7,  7,  7,  7,  5,  3,
     2,    3,  3,  3,  3,  3,  3,  2,
     0,    0,  0,  0,  0,  0,  0,  0,
// these are probably black
     0,    0,  0,  0,  0,  0,  0,  0,
     2,    3,  3,  3,  3,  3,  3,  2,
     3,    5,  7,  7,  7,  7,  5,  3,
     3,    4,  7, 10, 10,  7,  4,  3,
     3,    3,  6, 10, 10,  6,  3,  3,
     2,    2,  5,  5,  5,  5,  2,  2,
     0,    0,  0,  0,  0,  0,  0,  0,
     0,    0,  0,  0,  0,  0,  0,  0
   };



and

Code:

// knight
                    mob = 0;
                    if( me == White )
                        {
                        if( board->square[from - 17] == WP )
                            mob += KnightOutpost[me][SquareTo64[from]];

                        if( board->square[from - 15] == WP )
                            mob += KnightOutpost[me][SquareTo64[from]];
                        }
                    else
                        {
                        if( board->square[from + 17] == BP )
                            mob += KnightOutpost[me][SquareTo64[from]];

                        if( board->square[from + 15] == BP )
                            mob += KnightOutpost[me][SquareTo64[from]];
                        }
                  op[me] += mob;
                  }


Hope it helps somewhat...

Do you not check to see if the Knight can be dislodged by an enemy pawn? I thought that was the important bit....
