aLegendWai: After
, W is safely connected (unless the surrounding areas change!).
Why the cut is impossible
aLegendWai: I am going to show all possible attempts to cut. If you are unsure why Keima watari can ensure the connection. It is worth reading on. I will show both the correct and wrong responses. So weaker players can avoid the wrong ones.
