Defaults to `None`. If bound to a game, any value set for
|
||||
`"PlyCount"` is ignored and instead the real ply count of the
|
||||
game is the value.
|
||||
Aditionally the `"FEN"` header can not be modified if the game
|
||||
already contains a move.
|
||||
|
||||
These headers are required by the PGN standard and can not be
|
||||
removed:
|
||||
|
||||
`"Event`":
|
||||
The name of the tournament or match event. Default is `"?"`.
|
||||
`"Site`":
|
||||
The location of the event. Default is `"?"`.
|
||||
`"Date`":
|
||||
The starting date of the game. Defaults to `"????.??.??"`. Must
|
||||
be a valid date of the form YYYY.MM.DD. `"??"` can be used as a
|
||||
placeholder for unknown month or day. `"????"` can be used as a
|
||||
placeholder for an unknown year.
|
||||
`"Round`":
|
||||
The playing round ordinal of the game within the event. Must be
|
||||
digits only or `"?"`. Defaults to `"?"`.
|
||||
`"White`":
|
||||
The player of the white pieces. Defaults to `"?"`.
|
||||
`"Black`":
|
||||
The player of the black pieces. Defaults to `"?"`.
|
||||
`"Result`":
|
||||
Defaults to `"*"`. Other values are `"1-0"` (white won),
|
||||
`"0-1"` (black won) and `"1/2-1/2"` (drawn).
|
||||
|
||||
These additional headers are known:
|
||||
|
||||
`"Annotator"`:
|
||||
The person providing notes to the game.
|
||||
`"PlyCount"`:
|
||||
The total moves played. Must be digits only. If a `game`
|
||||
parameter is given any value set will be ignored and the real
|
||||
ply count of the game will be used as the value.
|
||||
`"TimeControl"`:
|
||||
For example `"40/7200:3600"` (moves per seconds : sudden death
|
||||
seconds). Validated to be of this form.
|
||||
`"Time"`:
|
||||
Time the game started as a valid HH:MM:SS string.
|
||||
`"Termination"`:
|
||||
Can be one of `"abandoned"`, `"adjudication"`, `"death"`,
|
||||
`"emergency"`, `"normal"`, `"rules infraction"`,
|
||||
`"time forfeit"` or `"unterminated"`.
|
||||
`"Mode"`:
|
||||
Can be `"OTB"` (over-the-board) or `"ICS"` (Internet chess
|
||||
server).
|
||||
`"FEN"`:
|
||||
The initial position if the board as a FEN. If a game parameter
|
||||
was given and the game already contains moves, this header can
|
||||
not be set. The header will be deleted when set to the standard
|
||||
chess start FEN.
|
||||
`"SetUp"`:
|
||||
Any value set is ignored. Instead the value is `"1"` is the
|
||||
`"FEN"` header is set. Otherwise this header does not exist.
|
||||
|
||||
An arbitrary amount of other headers can be set. The capitalization
|
||||
of the first occurence of a new header is used to normalize all

further occurences to it. Additional headers are not validated.
