What is “looking for a place to resign” in go?
Sensei’s Library explains under Looking for a place to resign that the expression ‘looking for a place to resign’ means choosing a move which obviously does not work and resigning when your opponent responds correctly.

Sensei’s Library also has an article on How to resign which sketches when to resign and enumerates ways of formally indicating that you do so. It also links to more extensive discussions of the etiquette, indicating in particular that it is a bad habit not to resign when you clearly cannot win.

I apologise for not having found this earlier; my mistake was searching without quoting the entire expression ‘looking for a place to resign’ — without quotes there is an enormous amount of noise, but with quotes Duck Duck Go gave four matches: this question, Tom Au’s answer and the above articles in Sensei’s Library.
