Split shape  

Locally speaking this ripped keima is very bad for White: the stones white+circle and white+square cannot help each other at all.

The history?  

White must have some extremely good reason to allow B3 here. Mostly White should answer B1 at B3, founded on basic instinct.

Possible dodging  

It is conceivable that White might want instead to treat white+circle as a sacrifice, with W2 and W4 here.

This is from six good and six bad shapes.

PJTraill: Do the Asian terms given refer only to this shape (a ripped keima), or to any split shape, such as a ripped tobi??
