Query about notation

[cms271828]

Hi,

If there are two pieces on the same file that can go to the same destination square, we just give the rank number eg..

Q4d4 or Q1d4,

And if there are two pieces on same rank that can go to the same destination square, we just give the rank number eg...
Qad4 or Qdd4.

In the unlikely event of 3 pieces (2 on same file, 2 on same rank), eg
Queens on a1,a4,d1, and the target square is d4, we can't just give the file, or the just rank, so do we have to give whole square?
Such as Qa1d4 or Qa4d4 or Qd1d4?

Thanks very much.

I don't think current FIDE rules of algebraic notation cover this case, and i had in the past the same question. I asked and the answer they gave to me was the one you suspected. You give both the file first and the rank second, if it is necessary to give both.

For example in the following position:
We write 1.Q5e5 for the move of the a5-Queen to e5.
We write 1.Qee5 for the move of the e1-Queen to e5.
We write 1.Qa1e5 for the move of the a1-Queen to e5.

Disambiguating moves

If two (or more) identical pieces can move to the same square, the piece's initial is followed by (in descending order of preference):

1. the file of departure if they differ;
2. the rank of departure if the files are the same but the ranks differ;
3. Both the rank and file if neither alone uniquely defines the piece (after a pawn promotion, if three or more of the same piece able to reach the square).

For example, with two knights on g1 and d2, either of which might move to f3, the move is indicated as Ngf3 or Ndf3, as appropriate. With two knights on g5 and g1, the moves are N5f3 or N1f3. As above, an x may be used to indicate a capture: for example, N5xf3.

In my opinion, the most appropriate standard on chess notation is the PGN standard instead of FIDE standards if you are developing software. There seem to be many varieties of SAN (like a8Q, a8=Q) but whatever the PGN standard goes by should be safe for software purposes.

If 2 pieces of the same color can go to the same square then we use something like:

Nbd4 or Nfd4

This assumes that both moves are legal. If one of the Knights, say the one on the f file, is pinned (absolute pin) to its King, then that Knight cannot legally move. In this case the correct notation would be: Nd4 since there is no longer ambiguity. It then would be INCORRECT to say Nbd4 where there is NO ambiguity.

An interesting case is if one, not both, of the 2 ambigous Nd4 moves causes a discovered check or checkmate by a 3rd piece. Does the check (+) or checkmate (#) symbol solve the ambiguity? The answer is no. Disambiguity notation is still required.

Hi everyone,

I come to this topic because in testing the move disambiguation for the SAN notation I got the following position. Black to move.

[d]1kq1rQQQ/5R2/b2q4/q2p2Q1/2qB2B1/q1P5/6P1/3Q3K b - -

I have some doubts regarding the right way to disambiguate some of the black Queens moves. As an example, the UI gives the following notations:

• Qa5xc3

• Qa5a4

• Qa3c5

According to the rules https://en.wikipedia.org/wiki/Algebraic ... ting_moves, at the point 3 both file and rank shall be used [to disambiguate] only when "neither alone is sufficient to identify the piece". But in those three example cases it's enough to use the rank alone to disambiguate the Queen to be moved. Therefore, I suppose the correct way should be:

• Q5xc3

• Q5a4

• Q3c5

Can anyone give me some clarification?

In case someone needs the complete list, this is the way I understood the proper disambiguation:
Ka8 Bb7 Bb5 Q4c5 Q4c6 Q4c7 Qxd4 Qd3 Qe2 Qf1+ Qcxc3 Qcb3 Qca2 Qcb4 Qca4 Qcb5 Qab6 Qac7 Qad8 Qab5 Q5c5 Q5b4 Q5xc3 Q5a4 Qdd7 Qdd8 Qe7 Qxf8 Qde6 Qf6 Qg6 Qh6+ Qe5 Qf4 Qg3 Qh2+ Qdc5 Qdb4 Qdc6 Qdb6 Qdc7 Q3a4 Q3b4 Q3c5 Qab3 Q3xc3 Qb2 Qc1 Qaa2 Qa1 Rxf8 Re7 Re6 Re5 Re4 Re3 Re2 Re1+ Rd8 Qcd8 Qcd7 Qce6 Qf5 Qxg4 Q8c7 Q8c6 Q8c5 Qb7

Thanks to everyone who will take some time to answer.
Greetings, and stay healthy!

You are correct.
Whatever "the UI" is, was lazy.
Minimal is better when it can be achieved, but on rare occasions I see errors even in top engines and GUIs in representing a move by not adding enough disambiguation.
