It is a good puzzle. Don't spoil it by stretching it out with irrelevant moves.

Last few moves are unnecessary

Yeah good puzzle but what's the objective? I like the fact that the "solution" involves winning the exchange by getting White's Queen (well yeah you would like that if you were playing Black wouldn't you?) but I didn't know that I was "supposed" to continue in order to get a passed pawn. So, as the previous commenters say, there is a feeling of "irrelevant" or "unnecessary" subsequent moves, in the manner in which the compu-board is set up to require us to figure out something else even after we've won the White Queen. If you put in a title that pointed this fact out, somehow (without giving away the solution) then maybe it would work better? How about entitling it, "A Queen is not enough!" or similar?

I should have included the later moves in note form rather than presenting them as core contents. It must have frustrated some dedicated puzzle solvers. Many apologies for that.
