Subsets and Splits

Top Chess Positions with Scores

The query retrieves a portion of the dataset with specific feature values, but it lacks aggregation or filtering that provides deeper insights.

Non-mate Chess Positions

Returns a selection of chess positions (FEN notation) where the game did not have a mate, which is a basic filtering query.

Filtered Chess Positions

Retrieves a subset of chess positions (FEN) along with their mate scores, focusing on games that ended within a certain number of moves.

Filtered Chess Positions

The query retrieves a large number of chess positions (in FEN format) where the material difference is small (between -6 and 6), providing basic insight into balanced chess scenarios.
