The 20 question format has been one of "us against the poser". I don't recall presenting any rules of any kind that might be helpful to those who might enjoy a more competitive nature to it. Most here are happy to help one another reach the final answer within the 20 question limit. Often, some will intentionally allow another to have a shot at winning. Or, in my case sometimes, not have to come up with another clever question that may be time consuming, especially with this format.

This is an "all for one and one for all" approach that I think most will agree with is the appropriate setting. We also like to try various techniques to get the answer quicker, so I don't object to those who occasionaly try a riffle approach, compared to the shotgun method. If we wanted, we could always get the answer to questions like this one by cutting the RA and DEC ranges in half with each guess, but that would be too easy and cold.

I hope you hang with us, Centaur. There really are no losers here.
