Dataset Details

Dataset Sample

One row of the dataset looks like this:

{
 'name': 
 'pgn': 
 'uci': 
 'epd':
}

Dataset Fields

Every row of the dataset contains the following fields:

• name: string, the name of the opening in English.
• pgn: int, the sequence of moves leading to the opening position. If not unique, the moves are the most common ones leading to that opening.
• uci: int, the same moves described by the pgn field in UCI notation.
• epd: int, the EPD (FEN without move numbers) of the opening position, en passant field only if legal

Dataset Conventions

• Title case is used for opening names.
• Names are structured like Opening family: Variation, Subvariation, ..., e.g., Sicilian Defense: Najdorf Variation, English Attack.
• The suggested way to classify games is to play moves backwards until a named position is found. To make this work well with common transpositions, multiple entries for a single opening may be added.
• However, each name has a unique shortest line. If necessary, a distinguishing move is appended, e.g., King's Gambit Accepted: Schurig Gambit, with Bb5.
