I believe that chess and poker questions would ultimately find a larger audience here on the board and card games (BCG) site, with the larger number of viewers more than making up for the "experts" that do (or don't) populate the other sites just because they are separate.
As you can see from the above Q and A, the management of the Stack Exchange disagrees with me. That's their prerogative.
What are MY prerogatives? Should I "vote with my feet," by asking future chess and poker questions on this site instead? More to the point, is there a way to move the existing questions I have on those sites to this one?
Apparently one reason why "Magic the Gathering" (MTG) was repatriated to this site, was because there were as many or more MTG questions here on BCG than on the "separate" MTG site, even though it was (at the time) actually larger than the chess and poker sites. Would moving one's questions here from the other sites help to tip the balance?
