Answers.Body: <p>Pretty hopeless unless your opponent blunders. Your only strategy is to avoid rook trades and use your knight to set up a fork. Unfortunately, you have no immediate move that proceeds with this strategy. If your rook moves, you well lose your knight. Your king has no legal moves. And if you move your night then Rd5 is mate. Your only hope is to play Na6, in the hope that your opponent misses mate in 1!</p>
