Live Small
Keywords: MiddleGame, Strategy
Forcing (or allowing) an opponent to "live small" is sometimes a good strategy or tactic, especially for Black in a handicap game. This means to let the opponent live by making their group heavy (too big to easily sacrifice) and over-concentrated so that the opponent has spent many stones to make a small inefficient territory.
Forcing the opponent to live small is a good antidote to kyu disease.
