Editing Portable Game Notation (section)

==== Optional tag pairs ====
The standard allows for other optional tag pairs. The more common ones include:

{{aligned table|class=wikitable
|cols=2
|col1header=on
|col1style=text-align:left;
| Annotator| The person providing notes to the game.

| PlyCount| String value denoting the total number of half-moves played.

| TimeControl| e.g. {{code|40/7200:3600}} (moves per seconds: sudden death seconds)

| Time| Time the game started, in {{code|HH:MM:SS}} format, in local clock time.

| Termination| Gives more details about the termination of the game. It may be {{code|abandoned}}, {{code|adjudication}} (result determined by third-party adjudication), {{code|death}}, {{code|emergency}}, {{code|normal}}, {{code|rules infraction}}, {{code|time forfeit}}, or {{code|unterminated}}.

| Mode| {{code|OTB}} ([[over-the-board]]) {{code|ICS}} (Internet Chess Server)

| FEN| The initial position of the [[chessboard]], in [[Forsyth–Edwards Notation]]. This is used to record partial games (starting at some initial position). It is also necessary for chess variants such as [[Chess960]], where the initial position is not always the same as traditional chess.
:If a FEN tag is used, a separate tag pair {{code|SetUp}} must also appear and have its value set to {{code|1}}.
