 R4a5? Something about not having two of the same letters next to each other for clarity?

 

Now off to see if I am right happy.png

Raa5 sure

But how is that anymore definitive than old school
QR-R4?

Why did we go European style?
Somebody remind me...

 I'm thinking its Raa5. Although R4a5 does work as Martin suggests.

Urk,

We went to algebraic notation because it easier/faster to write down, and it is the same notation used for both sides of the board.

Didn't descriptive require that the original Queen's Rook get the QR designation?  So, in the above diagram, which one is really that rook? wink.png

 

In algebraic you don't have mess with that and each square only has one designation.

 

I looked up the rule but I won't spoil anything for anyone by saying if I was wrong or right.

From the FIDE laws of chess, Paragraph C10

 

Therefore Raa5 is prefered.

 

If two identical pieces can move to the same square, the piece that is moved is indicated as follows:

  1. 1. If both pieces are on the same rank: by a) the abbreviation of the name of the piece, b) the file of departure, and c) the square of arrival.
  2. 2. If both pieces are on the same file: by a) the abbreviation of the name of the piece, b) the rank of the square of departure, and c) the square of arrival.

If the pieces are on different ranks and files, method 1 is preferred.

Examples:

  1. There are two knights, on the squares g1 and e1, and one of them moves to the square f3: either Ngf3 or Nef3, as the case may be.
  2. There are two knights, on the squares g5 and g1, and one of them moves to the square f3: either N5f3 or N1f3, as the case may be.
  3. There are two knights, on the squares h2 and d4, and one of them moves to the square f3: either Nhf3 or Ndf3, as the case may be.
  4. If a capture takes place on the square f3, the notation of the previous examples is still applicable, but an x may be inserted: 1) either Ngxf3 or Nexf3, 2) either N5xf3 or N1xf3, 3) either Nhxf3 or Ndxf3, as the case may be.

What is the purpose of the question?

1. For "trivia"? To test the audience. Don't do that.

2. For yourself?

3. For a common transmission.

2. Like you said: a4-Rook to the a5-square.

3. Use a computer. Input the moves of a game into a computer. The computer will record a common format of transmission.

It is in all arts. In all times.

1. Don't be "quizzing" people, just for the heck of it.

2. If you write down something for yourself, it doesn't matter what system you use, as long as you can recreate it.

English: tip toe.

Bodybuilidng: calf raise.

Ballet (universal): relevé

Computers standardize things. Handwriting. Everyone's handwriting is unique. On a key board, they are converted into types. A "type" writer, typewriter. creates a common form for transmission.

The concepts in my answers apply to all arts, to all times.

Why do you ask why?

Why you do something determines how you do something.

You don't ask how before telling us (and yourself) why.

It's not answering me.

It's answering yourself.
