These basic values are modified by other factors such as the position of the pieces ( e. g. advanced pawns are usually more valuable than those on their starting squares ), coordination between pieces ( e. g. a bishop pair usually coordinates better than a bishop plus a knight ), and the type of position ( knights are generally better in closed positions with many pawns, while bishops are more powerful in open positions ).
