Smart Game Format File – file format by Anders Kierulf
SGF (Smart Game Format File) is a text-based file format used to store game records for board games like Go, chess, and Othello. It allows for the recording of game moves, variations, and annotations, enabling players to analyze and review games for study and improvement.
Smart Game Format File (SGF)
A Smart Game Format (SGF) file is a standardized file format used to store and exchange game information, particularly in the context of Go, a board game of strategy. It was developed by Anders Kierulf and provides a comprehensive and structured method for capturing game data, annotations, commentaries, and metadata.
SGF files are text-based and utilize a tree-like structure to organize game elements. The root node represents the overall game, while child nodes contain specific details such as moves, variations, comments, and player information. Each node is defined by a property-value pair format, where properties describe the node’s attributes and values specify the content. This structure allows for efficient storage, retrieval, and manipulation of game data.
Using Dedicated Software
For optimal SGF file viewing and editing, dedicated software is recommended. These applications provide specialized tools and features tailored to the specific requirements of SGF files. One popular option is Smart Go, a comprehensive program designed specifically for Go enthusiasts. It allows users to open, analyze, and play Go games stored in SGF format. Other notable software options include Golaxy and Lizzie, which offer similar capabilities.
Alternative Methods
In the absence of dedicated software, alternative methods can be employed to open SGF files. One approach is to use a text editor, such as Notepad++ or TextEdit. While text editors lack the specialized features of dedicated software, they provide a basic platform for viewing the contents of an SGF file. The syntax can be somewhat complex, but it is possible to identify game information, move sequences, and commentary. Another option is to use online SGF viewers, such as the one provided by Sensei’s Library. These web-based tools allow users to open and explore SGF files without installing dedicated software.
Smart Game Format (SGF)
The Smart Game Format (SGF) was developed by Anders Kierulf to provide a standardized method of recording Go games. It is a flexible and extensible text format that allows for the representation of a wide range of game information, including moves, comments, variations, and player information. SGF files are extensively used by Go players worldwide for sharing, storing, and analyzing games.
SGF files are typically structured into properties and sequences. Properties contain key-value pairs that specify game metadata, such as the name of the players, the date of the game, and the handicap. Sequences, on the other hand, represent the moves of the game. Each move is encoded as a pair of coordinates that indicate the intersection on the Go board where the stone was played. SGF files can also include comments, which are used to annotate specific moves or positions. Additionally, SGF files can contain variations, which allow for the representation of alternative sequences of moves. This enables players to explore different lines of play and analyze potential outcomes.
