In the Yunguseng Dojang‘s first lecture of season 26, Hwang In-seong 8-dan showed the “pinch” tesuji. This name comes from the Korean word for the kind of move that is called “atekomi” in Japanese.

It’s a bit like atekomi, but here the move is an attachment, not connected to own stones. Aims at connecting or cutting or giving atari. [Source] This move has been called “diagonal wedge” or “angle wedge” in English.
One kind of atekomi. It feels like ramming (rushing, crashing, thrusting) into the opponent’s stones. Contrast with sashikomi. [Source]
