Body: <p>In the following example (and similar situations you can make up), both queens can capture the knight. If for instance the queen on f5 takes the knight, this could be written as: Qfxd3 or as Q5xd3. Is there a preference/guideline/law/... for using one or the other notation in this case? I am specifically interested in notations made by humans in a normal game situation, not in PGN notation.</p>

  Chess Board is divided into 1-8 ranks and a-h files .
  
  Generally this problem arises with Rooks & Knights .
  
  When two Queens standing on two different Squares and have one common attacking Square or same Piece then we use for convenience
  
  Q Square number \* Square number .
  
  Here it would be either Qf5\*d3 or Qe2\*d3 .
  
  Any of the 64 Squares can be represented with the File + Rank convention . Always use the initial & final square number for better representation & avoiding ambiguity .
