+About 100M + 60M observations and targets generated from selfplay with a solver [https://github.com/PascalPons/connect4] with temperature.
+Observations from different depths are roughly uniformly distributed, altough later positions are reached less frequently.
+As a consequence early positions are duplicated and there is a small overlap between the train and test split (less than 3%).

+Observations are of shape (2,6,7) with binary (0 or 255) data.
 The first channel represents the stones placed by the current player while the second channel represent the stones played by the opoonent.
-The targets are the scores returned by the solver for placing the next stone in earch column. E.g. 1 / -1 means winning / losing on the last possible move, 2 / -2 means winning / losing one move before etc.
