Hi, oakfoam does not have such a feature yet. We have simelar features for debugging, e.g. we could ask with which probability does a playout make a point xy be owned black e.g. (and give an example playout)
But a possible approach would be straight forward I think. Change the definition of winning to winning at point xy. If you want to take the moyo effect into account possibly +(usual winning)/100 (100 is only an example for weighting of the usual win). A problem will be the definition of the last move made. I think all current strong mc programs relay to some extend on distance from the last move to narrow the search... As I am currently collecting ideas for regression tests, there is a good chance, that oakfoam will incorperate this kind of solver. At the moment I was planing only to implement: check probability of owning xy with a usual move, but the solver approach might give better and more reproducible results. I probably will give it a try:) Thanks!
