Unlike most "mate in two" puzzles, this one is unlikely to occur in a game. But it *is* possible to get to this position, and knowing that is the key to the solution. Since this isn't an ordinary chess problem and the solution requires a fair amount of inductive reasoning, I thought it appropriate to put this in net.puzzle, too. Try it, you'll see.
