It seems there's some arbitrage problem with these kinds of questions. Ostensibly, I could just pretend to be a beginner and then ask beginner questions like these and instantly attract 25 upvotes within a few days.
Are these kinds of questions really ok? If so, then should these kinds of questions really be ok? I think of making certain new questions or FAQs off-topic to prevent these kinds of things. r/chess has a "Helpful Links" part in the sidebar.
I mean, I have nothing against n00bs or anything, but what's to stop me or anyone from pretending to be a beginner and posting all these easily answered questions about basic things like pins or checkmates? I could even say I reached a stalemate (without using the term stalemate) and wonder the lone king can't move. I'll even make sure to use an image instead of FEN/PGN.
Some food for thought, I guess.
One idea came to mind as I finished typing all this. Perhaps migrate to the Board Games SE if it's too much of a beginner question. I was thinking it would be something a little (A LITTLE) like MathOverflow and Math.SE (not the best analogy which is why I emphasised 'little').
By the way, here is another example, but this time to do with etiquette/ethics/rules rather than actual gameplay.
