These points are just rule of thumb. Every piece that is active is worth more, any passive piece is worth less.
And this is the key point. Values are really only a useful guide for novice players, who as yet do not have the understanding to make a more specific assessment based on the requirements of the position in front of them.
In reality it depends WHICH piece(s) in WHICH position.
Just to make some comments on posts already made.
1) The author who assigned 10 points to a King was completely innaccurate - as amusingly exposed by 'P'
2) Connected passed pawns on the 6th = a rook? This makes no sense whatsoever. It depends entirely on the positional and material balance of the position (e.g. with just kings left, it surely equals 2 queens!?)
3) Whilst the bishop pair is considered superior in most positions to any other minor piece combination, a bishop and knight will often be as effective as two knights - particularly in open positions and advanced endgames
4) A king can only attack a maximum of 8 squares - not 9.
5) Rooks work better with knights than bishops? Not sure about that. Bishops and rooks on an open board have superior mobility and combine well in covering diagonals and ranks/files.
6) 3 moves = 1 pawn. That would have to be 3 very bad moves?!
7) The queen is assigned the value of 9 because she is considered equal to 3 minor pieces on an open board. However, the queens strength depends a great deal on the material balance. Her greater mobility is countered by the fact that the 3 pieces (or 2 rooks) can cooperate in both defence and attack. 2 rooks / 3 pieces are often therefore more than a match, the specifics of the position nothwithstanding.
So use the relative values as a guide as a beginner. Do not make decisions based on them without considering the specifics of the position infront of you. It is better to have an understanding of strategy, tactics, endgame theory and positional aspects of the game, and base your decisions on these.
