I added the sentence "Of the above, the six properties BC, JD, LC, LT, OH, WC are not in FF[4]." These properties are BC Black Country WC White Country JD Japanese Date LC Number of byo-yomi periods LT Length of byo-yomi periods OH Old Handicap > BS (Black Species) and WS (White Species) are valuable to distinguish > computer players from human players.

For me this markup is intended to make automatic selection possible: selecting games on date, players, event etc. A natural type of question asks for games of Cho Chikun against a computer. I use standardized comments "GC[W is a computer]", but WS[1] is easy to use. Do people recall why it was removed from FF[4]?

I think we agree, and the current text says what you want. But it also describes what is out there. On output, one should follow the preferred style. But on input one might wish to also recognize other common styles. > Some properties are crucial to describe Go games and problems > in a standardized way, the main idea behind SGF.

In my SGF collections these property labels disappear in the noise, and where used have various meanings. (I see for example as root property GB[J], where the J may denote "Japanese". TE is very common as root property, an SGF2 synonym for EV.) Can you point to SGF collections where these properties are used? >> In a few cases I do not know the meaning of some labels - information is >> welcome. For example, what is AX?
