I think it was Telegraph Go where I first heard someone calling this breaking the bamboo shape.
(auto subtitles that I’ve tried to fix below, but listen to it if you want above)
32:01
important moves for the Liberty situation for The Cutting situation for his group. Gu Zihao strikes, he breaks
32:08
the bamboo - you should always think about breaking the bamboo whenever it is at all possible.
32:15
yeah this, this strike is actually putting black into a bit of a bind. it’s very difficult to save these two stones
32:21
but if you don’t then this white group will just save very naturally if black doesn’t get to press this white group
32:27
down and gain quite a lot then he can’t ever win the game so black must save like this and white presses like that
Davies in his book Tesuji calls it the slapping tesuji
but I can understand why you migh want to give it a more memorable name when it comes up every so often in fighting shapes.
