Rook h1 — 0 ; —

0 57% of people got this right, and 4 people solved it...Mellor, at least how many people attempted the problem, if no rounding was involved? Thanks for the edit suggestion, Stephen.

I'm not sure what you're on about, but 10 attempts and 4 solvers at the moment. It will have been 57% after 7 attempts

Also, is Queen e8 checkmate? There is another move which you have missed but counted this one instead. And for both of the Knights, it's g6 not g5

Yes, qe8 lets black play kg7. Instead, you missed qf6#

I suppose I got lucky, then. Thanks for catching the mistakes! To clarify my question: at least many people attempted the problem if the percentage of solvers remained at 57%, but without rounding?
