The fundamental difference is that in chess, if you use simple concepts
such as I outlined, you can understand a position and tell who is winning
a large percentage of the time. In Go, you undersand NOTHING until you
have decided which stones are dead, and that is a fundamentally hard
problem.
maybe a probability of being dead is better in the sense that a lot of
"dead" stones get rescued later on due to liberties changing or ignoring ko
threats. it makes sense to focus on "dead" stones, but it may be somewhat
of a red herring?
