Another idea that has been kicked around is adding an eval bonus for the side to move, although, personally, I don't think it's a good idea. I think it is reasonable, however, for the king safety algorithm to consider the side to move in determining how serious a threat is.

Another very important thing is knowing which endgames are drawn.

Note that 1,3,3,5,9 is not the shannon way of counting,
but rather the Max Euwe manner of counting.

Max Euwe was world champion 1935-1937 and a very influental person in the chess scene.

Another system is used by Max Euwe and Hans Kramer in Volume 1 of their The Middlegame, with values:

* pawn = 1
* knight = 3½
* bishop = 3½
* rook = 5½
* queen = 10.

(1) The relative values of queen, rook, bishop, knight and pawn are about
9, 5, 3, 3, 1, respectively.
