A few days ago, one of my questions on overcalls in bridge was closed by a moderator, apparently for being "subjective."
What are rules for an overcall that have wide acceptance?
When this happened, I reviewed the entries on the internet that I had consulted. Their generally vague and confusing discussions 1) reminded me of why I had asked the question, and 2) seemed to support the moderator's decision to close the question.
Several days later, I stumbled (after trial and error) on this answer.
It seemed to meet all the requirements of a good Stack Exchange answer: 1) It was "objective" insofar as it not only described the requirements for an overcall but put them into a formula 2) "expert," insofar as it was not a typical "wiki" article, but apparently part of a book and 3) clear, insofar as it created a "light bulb" moment in my head. I would have gladly accepted an answer that was a takeoff on this post as "authoritative."
The question was closed because someone apparently honestly believed that an objective answer based on "facts, references, and specific expertise" would be hard to come by. I have, in fact, found such an answer. Is this grounds for reopening the question?
