Hi Sighris, i have always thought that creating algorithms for arbitrary large go boards should enlighten us in regards to playing on smaller go boards.
A humans performance doesn't differ that much on differently sized large go boards and it scales pretty well. For example one would find it rather easy to evaluate large dragons or ladders. The currently used neural algorithms (NNs) do not perform well in this regard. Maybe some form of RNN could be integrated into the evaluation.
