Watcher
Base case: we have two correctly recognized positions differing by a single move (single added stone). Easy.
Issues:
* illegal positions -> ignorable
* positions unreachable from the previous state
* reachable from any past state. (Incorrect states inbetween). How to pick the correct leaf of such a tree?
* reachable by more than one move. Issues with branching factor.
* board shifts -> repaired manually (or automatically), further positions have to be reevaluated
* stone shifts
* stone stops being recognized -> fixable manually and even ignorable
* stone is recognized at an empty intersection. It can be occupied later for real. What do?
