[FEN "8/8/8/8/8/pNnbPPpN/RBppPbrP/pkKPrqQR b - - 0 1"]
I was introduced to a challenge a few weeks ago with the above position. The challenge is to move the Black Knight such that it must always be three squares in the third row from the right, the point is to capture all pieces with the Black Knight. The order of the other pieces doesn't matter.
While an answer is awesome, what I'm mainly interested in is, is this really a thing?
