A Dubious Approach Move by Richard Bozulich |
|
One of the basic strategic principles of go is to avoid leaving behind weak groups that your opponent can attack. If you do have any weak groups, strengthening them should be your first priority. On the other hand, if you find that your opponent has a weak group, you should attack it as soon as possible. In the process of attacking it, you should be able to secure territory, gain influence, or both.
