SGF 属性 (FF[4])
走子属性
属性:  B
属性值: 走子
属性类型:    走子
功能:  执行一个黑走子。在实战对局集中这是最常用的属性之一。
        只要该属性在句法上是正确的，走子就应当被执行，即使该走子不符合规则（例如由KO属性指定的强制走子）。
        参看如何执行一个围棋走子。
        属性 B 和属性 W 不能处于同一个节点中。
相关属性:    W, KO

属性: KO
属性值: 无值
属性类型:    走子
功能:  执行一个由属性 B 或 W 指定的走子，即使该走子不符合规则。
        这是一个可选的属性，SGF阅读器本身应当执行所有的走子。
        设立该属性是为了使其它应用软件（如计算机对局者）可以更容易处理不符合规则的走子。
        在包含属性 KO 的节点中，如果没有黑走子或白走子，则是非法的。
相关属性:    W, B

属性: MN
属性值: 数
属性类型:    走子
功能:  设定手数的数值，就是指定该节点中走子具有这个确定的手数。
        该属性对于分支或打印很有用。
相关属性:    B, W, FG, PM

属性:  W
属性值: 走子
属性类型:    走子
功能:  执行一个白走子。在实战对局集中这是最常用的属性之一。
        只要该属性在句法上是正确的，走子就应当被执行，即使该走子不符合规则（例如由KO属性指定的强制走子）。
        参看如何执行一个围棋走子。
        属性 B 和属性 W 不能处于同一个节点中。
相关属性:    B, KO


设置属性
限制
属性 AB, AW 和 AE 指定的点必须唯一，就是说，在一个节点中在相同的点上放置不同色的棋子是非法的。不能使用属性 AB, AW 和 AE 改变棋盘，就是说，在已经有黑子的点上再使用属性 AB[] 放置一枚黑子是不好的风格。应用软件会删除这个值并且给出一条警告。属性:   AB
属性值: 由棋子组成的列表

        even result for both players and that this is a main
        variation of this joseki/opening.
        This property must not be mixed with UC, GB or GW
        within a node.
相关属性:    UC, GW, GB

属性: GB

        to create this gametree.
        The name should be unique and must not be changed for
        different versions of the same program.
        The version number itself may be of any kind, but the format
        used must ensure that by using an ordinary string-compare,
        one is able to tell if the version is lower or higher
        than another version number.
        Here's the list of known applications and their names:

        Application          System   Name
        ---------------------------  -----------  --------------------
        [CGoban:1.6.2]           Unix     CGoban

相关属性:    FF, GM, SZ, ST, CA

属性: CA
属性值: 单文本
属性类型:    根
功能:  Provides the used charset for SimpleText and Text type.
        Default value is 'ISO-8859-1' aka 'Latin1'.
        Only charset names (or their aliases) as specified in RFC 1345
        (or updates thereof) are allowed.
        Basically this field uses the same names as MIME messages in
        their 'charset=' field (in Content-Type).
        RFC's can be obtained via FTP from DS.INTERNIC.NET,
        NIS.NSF.NET, WUARCHIVE.WUSTL.EDU, SRC.DOC.IC.AC.UK
        or ftp://ftp.imag.fr/pub/archive/IETF/rfc.
相关属性:    FF, C, text type

属性: FF
属性值: 数 (range: 1-4)
属性类型:    根
功能:  Defines the used file format. For difference between those
        formats have a look at the history of SGF.
        Default value: 1
        Applications must be able to deal with different file formats
        within a collection.
相关属性:    GM, SZ, ST, AP, CA

属性: GM
属性值: 数 (range: 1-16)
属性类型:    根
功能:  Defines the type of game, which is stored in the current
        gametree. The property should help applications
        to reject games, they cannot handle.
        Valid numbers are: Go = 1, Othello = 2, chess = 3,
        Gomoku+Renju = 4, Nine Men's Morris = 5, Backgammon = 6,
        Chinese chess = 7, Shogi = 8, Lines of Action = 9,
        Ataxx = 10, Hex = 11, Jungle = 12, Neutron = 13,
        Philosopher's Football = 14, Quadrature = 15, Trax = 16,
        Tantrix = 17, Amazons = 18, Octi = 19, Gess = 20.
        Default value: 1
        Different kind of games may appear within a collection.
相关属性:    FF, SZ, ST, AP, CA

属性: ST
属性值: 数 (range: 0-3)
属性类型:    根
功能:  Defines how variations should be shown (this is needed to
        synchronize the comments with the variations). If ST is omitted
        viewers should offer the possibility to change the mode online.
        Basically most programs show variations in two ways:
        as markup on the board (if the variation contains a move)
        and/or as a list (in a separate window).
        The style number consists two options.
        1) show variations of successor node (children) (value: 0)
           show variations of current node   (siblings) (value: 1)
           affects markup & list
        2) do board markup         (value: 0)
           no (auto-) board markup (value: 2)
           affects markup only.
           Using no board markup could be used in problem collections
           or if variations are marked by subsequent properties.
           Viewers should take care, that the automatic variation
           board markup DOESN'T overwrite any markup of other
           properties.
        The  final number is calculated by adding the values of each
        option. Example: 3 = no board markup/variations of current node
                 1 = board markup/variations of current node
        Default value: 0
相关属性:    C, FF, GM, SZ, AP, CA

属性: SZ
属性值: (数 | composed 数 ':' 数)
属性类型:    根
功能:  Defines the size of the board. If only a single value
        is given, the board is a square; with two numbers given,
        rectangular boards are possible.
        If a rectangular board is specified, the first number specifies
        the number of columns, the second provides the number of rows.
        Square boards must not be defined using the compose type
        value: e.g. SZ[19:19] is illegal.
        The valid range for SZ is any size greater or equal to 1x1.
        For Go games the maximum size is limited to 52x52.
        Default value: game specific
                   for Go: 19 (square board)
                   for Chess: 8 (square board)
        Different board sizes may appear within a collection.
        See move-/point-type for more info.

属性: DT
属性值: 单文本
属性类型:    对局信息
功能:  Provides the date when the game was played.
        It is MANDATORY to use the ISO-standard format for DT.
        Note: ISO format implies usage of the Gregorian calendar.
        Syntax:
        "YYYY-MM-DD" year (4 digits), month (2 digits), day (2 digits)
        Do not use other separators such as "/", " ", "," or ".".
        Partial dates are allowed:
        "YYYY" - game was played in YYYY
        "YYYY-MM" - game was played in YYYY, month MM
        For games that last more than one day: separate other dates
        by a comma (no spaces!); following shortcuts may be used:
        "MM-DD" - if preceded by YYYY-MM-DD, YYYY-MM, MM-DD, MM or DD
        "MM" - if preceded by YYYY-MM or MM
        "DD" - if preceded by YYYY-MM-DD, MM-DD or DD
        Shortcuts acquire the last preceding YYYY and MM (if
        necessary).
        Note: interpretation is done from left to right.
        Examples:
            1996-05,06 = played in May,June 1996
            1996-05-06,07,08 = played on 6th,7th,8th May 1996
            1996,1997 = played in 1996 and 1997
            1996-12-27,28,1997-01-03,04 = played on 27th,28th
            of December 1996 and on 3rd,4th January 1997
        Note: it's recommended to use shortcuts whenever possible,
        e.g. 1997-05-05,06 instead of 1997-05-05,1997-05-06

属性值: 无值 | composition of 数 ":" SimpleText
属性类型:    -
功能:  The figure property is used to divide a game into
        different figures for printing: a new figure starts at the
        node containing a figure property.
        If the value is not empty then
        - Simpletext provides a name for the diagram
        - Number specifies some flags (for printing).
          These flags are:
            - coordinates on/off (value: 0/1)
            - diagram name on/off (value: 0/2)
            - list moves not shown in figure on/off (value: 0/4)
              Some moves can't be shown in a diagram (e.g. ko
              captures in Go) - these moves may be listed as text.
            - remove captured stones on/off (value: 0/256)
              'remove off' means: keep captured stones in the
              diagram and don't overwrite stones played earlier -
              this is the way diagrams are printed in books.
              'remove on' means: capture and remove the stones from
              the display - this is the usual viewer mode.
              This flag is specific to Go (GM[1]).
            - hoshi dots on/off (value: 0/512)
              This flag is specific to Go (GM[1]).
            - Ignore flags on/off (value: 32768)
              If on, then all other flags should be ignored and
              the application should use its own defaults.
          The final number is calculated by summing up all flag values.
          E.g. 515 = coordinates and diagram name off, remove captured
          stones, list unshown moves, hoshi dots off;
          257 = coordinates off, diagram name on, list unshown moves,
          don't remove captured stones, hoshi dots on.
          (this is how diagrams are printed in e.g. Go World)
        Note: FG combined with VW, MN and PM are mighty tools to print
        and compile diagrams.

属性值: 数
属性类型:    后继性
功能:  This property is used for printing.
        It specifies how move numbers should be printed.
        0 ... don't print move numbers
        1 ... print move numbers as they are
        2 ... print 'modulo 100' move numbers
            This mode is usually used in books or magazines.
            Note: Only the first move number is calculated
            'modulo 100' and the obtained number is increased
            for each move in the diagram.
            E.g. A figure containing moves
                 32-78  is printed as moves 32-78
                102-177 is printed as moves  2-77
                 67-117 is printed as moves 67-117
                154-213 is printed as moves 54-113
        Default value: 1

属性类型:    后继性
功能:  View only part of the board. The points listed are
            visible, all other points are invisible.
            Note: usually the point list is given in compressed
            format (see 'point' type)!
            Points have to be unique.
            Have a look at the picture to get an idea.
            VW[] clears any setting, i.e. the whole board is
            visible again.
