I have just learned about Hidden Move Go and I have a problem.
Let us assume that one of our opponent’s hidden stones has only one liberty, i.e. it is in atari. But they don’t know that, because one of our three surrounding stones is hidden. So they play somewhere else and we play a stone filling the last liberty of their hidden stone. In this position we have no idea that we have captured a stone and our opponent has no idea that their stone is captured. Because of this, the table is wrong and it mustn’t be. How can we avoid that situation without the help of a third person? Any ideas or experiences?
