Why Tsumego is So Important?

In ancient China, people were not scoring territory at all, but instead just the stones on the board. So originally, Go was about "gaining life for as many stones as possible" instead of territory. Building a territory - i.e. an area where no opponent's stones are able to live - was just one strategy to secure life for many stones later. In other words, Go was just about life & death!

When the Japanese changed the rules to territory scoring as they found this more elegant than scoring stones, the rules of Go were cut apart from the original idea, which lead to the widespread misbelief among amateurs that Go would basically be about just fencing in points.
