This is my all time favorite chess problem.  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.
