Does this tesuji have an English name?

[wineandgolover]

In my most recent video, I wonder whether the reason I have never played this tesuji is because I never knew a name for it.

Is there a generally accepted English-language name for it? If not, should we create one?

It is a common enough sequence but I have never heard it described by any name.

"ko lock"

Cool, thanks! I've annotated the video (not visible on mobile OS's) and updated the info section of the video with the name.

Interesting. I've been playing the sequence for years never knowing it had a name. I guess that shows that you don't need the name to be able to play good moves.

I think that name was coined by Charles Matthews.

This tactic is as old as the hills; but the 'ko lock' name goes back to Victor Chow, a Chinese amateur now in South Africa.

So it doesn't have a name in Japanese. I was assuming that was the translation of the Japanese term. Most other go terms are.
