This is something I always wanted to know and still don't.
I understand balance as the middle point between two extremes. What I don't know is which two extremes should be analysed in order to decide someone has a "balanced play".
Options I see:
1 - Agressive/passive - if this is what the tag is about, a balanced player would not attack frequently, but would also refrain from using turtling strategies.
2 - Clever/dumb - if this is what the tag is about, a balanced player would not make the best micro/macro warfare decisions, but at the same time he does not make stupid "class A" mistakes.
There's also the possibility of balanced play referring to a different dichotomy. Anyway, what does is really mean?
Thanks in advance.
