Life In 19x19

The one space diagonal aka elephant jump is usually enough bad shape to be one of Fan Hui's basic 4 bad shapes (Ed will be pleased to see the ripped keima is number 1 )

Note also the ripped tobi of number 2.

Hi Buri, could you reference the name (or number/date, etc.) of Jennie's (or Guo Juan's) lecture(s), and how many minutes into it, etc.?
I have a feeling there's a misunderstanding/mis-interpretation of what was said in the lecture(s),
so let's first find out what was exactly presented in the lecture(s), then proceed from there.

Unfortunately, it's not so simple.
Sometimes, it is good shape; sometimes, it is not.
It depends on the exact board position.

Perhaps a better way to word this would be to say that the double diagonal (elephant's jump) is a shape with a natural weakness, namely that the opponent can play the middle point and threaten a very severe cut. Whether this natural weakness is going to be a problem will of course be context dependent.

Another such shape is the kick-extend shape -

This shape locally has two natural weak points for white (A and B), however there are still some times where the shape works and is effective.

Thank you for all the advice on this page, which has been at just the right level. As a beginner, it seems like there is a big gap between understanding the rules, and understanding why some natural-looking moves are bad, and this has narrowed it a little.
