user16067: When a capture can be made by two rooks, or two knights, etc., how does the notation clarify which piece makes the capture?
For example, if two pawns, one at e4 and one at c4, capture a pawn at d3, the notation will say exd3 or cxd3, sure.  But if two knights capture the same piece, how is that notated?  Or for two rooks, or queens?  In the case of the knight, it would only say Nxd3, but that doesn't clarify which knight took the piece.

user12873: Assume you have Knights on e5 and c5. If Nc5 captured on d3, you would write:
1...Ncxd3
If Ne5 captured on d3:
1...Nexd3
The key is using the column letter to distinguish pieces.
If the pieces are on the same column, such as Knights on e4 and e6, then you would distinguish via their row numbers. Example:
If Ne4 captured on g5, you would write:

N4xg5

If Ne6 captured on g5, you would write:

N6xg5

If you have the choice of distinguishing between column letter and row number, choose column letter. This isn't required by any means, but it tends to be the convention.  Example -- Rooks on e6 and g4.
If Re6 captured on g6, you should write:

Rexg6 (not R6xg6).


user825: Your two knights are on d2 and f2.
Ndxe4, Nfxe4,

Your two knights are on f2 and f6.
N2xe4, N6xe4

Your three knights are on d2, f2 and f6 (you promoted a pawn)
Ndxe4, Nf2xe4, N6xe4
