Life In 19x19

I am not quite sure if I understand correctly, so why would white "e" be annoying after black played "d"?

This story was translated by John Power and published in Go World issue number 50 (winter 1987-1988). There are other good stories in that issue, including the one which became the origin of the story about wearing down of the nail the right hand index finger.
Just a small sample of the wonders available in the DVDs of Go World

Connection, WHite "e" would be annoying to Black because it would block the large black group from access to the left side and also, at the same time, enlarge White's potential territory there.

Because if White played 'e' first, Black would most certainly not reply with 'd'. So after White 25, Black 'd'. White 'e' it's as though Black was forced to play 'd' after White 'e'. A very painful result. This sort of move analysis is called, 'tewari' analysis.
