I made this nifty problem after exploring after-game variations. Most of the time, I'm against player set-up problems (The type that requires you to play some moves set by the problem maker) since most of the time, they're unnecessary. But for this problem, I feel you can't fully appreciate Black's mistake unless you see it played out for yourself.
