| | PGN - Portable Game Notation (Site not responding. Last check: 2007-10-07) |
 | | This is a online version of the "Portable Game Notation Specification and Implementation Guide". |
 | | In my opinion, the sections 13 (PGN software), 19 (Canonical chess position hash coding), 20 (Binary representation), and 21 (E-mail correspondence usage) are obsolete and should be deleted: PGN reading/writing is a must for all chess software nowadays. |
 | | And I am not sure, whether there is a need for a canonical chess position hash coding, or for a special PGN E-mail correspondence usage. |
