NOTATION FOR KNIGHT AND BISHOP


In algebraic notation there is no differentiation in notation.
What Martin said. In addition, if both bishops or both knights can move to the chosen square then either a rank or file is added to it. Whenever possible file is used, Knights on a1 and e1, would be written Nac2 or Nec2. Knights on a1 and e3 would be written as Nac2 or Nec2. The only time rank is used, are when pieces are on the same file. Knights on a1 and a5. N1b3 or N5b3
