Line 32:
Disambiguation of pieces using notations like QBP and KR becomes awkward once the pieces have left their starting positions (or for pawns, left their starting files), and is impossible for pieces created by promotion (such as a second queen). So as an alternative, moves may also be disambiguated by giving the starting square or the square of a capture, delimited by parentheses or a slash, e.g. '''BxN/QB6''' or '''R(QR3)-Q3'''. Sometimes only the rank or file is indicated, e.g. '''R(6)xN'''.
When it is in unambiguous, the Q or K may be omitted from the file name, i.e. R rather than QR or KR, N rather than QN or KN, and B rather than QB or KB. For example, after 1.N-KB3 N-KB3, 2.P-B4 is sufficient to describe White's move without ambiguity. 2.P-QB4 would be redundant.
When listing the moves of a game, first the move number is written, then the move by White followed by the move by Black. If there is no appropriate move by White to use (e.g. if the moves are interrupted by commentary) then an ellipsis ("...") is used in its place.
