The dataset contains about 2.076M positions, with 76.1k positions reserved for the test split.
This dataset was created to provide rich supervision for Connect Four models.For each board position, the action value of every valid move is computed using a solver:
The core signal is the solver-produced negamax list over valid moves.Aside from threat annotations, most other targets can be derived… See the full description on the dataset page:
