I'm pretty new to this site but I've been around the SE network for a while. I've always liked the Programming puzzles and Code Golf site and I was thinking about doing here something that I've seen there for a while: a weekly challenge.
What I mean is posting a diagram asking for the best move in that particular position.
Are those kinds of questions allowed or would be closed as too broad?
EDIT: I've posted an example question: Chess challenge #1: Mate in one
EDIT 2: As it seems that the question has been well received I'll keep posting challenges on a regular basis. I will post tactical and strategical challenges and I won't post another one of the same kind until the existing one has been solved.
