Attacking Chess Puzzle of the Week - 2011-03-17

It has been a while since I posted a puzzle of the week.  I will provide the diagram and a FEN string this week and then provide the answer next week.  Feel free to discuss the problem and talk through it with everyone.  The next week I will provide the answer to the puzzle and then another puzzle to solve.

Studying chess tactics and puzzles is a very important step in learning chess and it will help all levels of players increase their skills and abilities.
