Daily puzzles #9.

hello!

yesterday's puzzle provoked a lot of comments, it means, I found a good one :)

some of comments were correct and their authors found a correct idea that is a bit unusual (I'm honestly not sure if I found it OTB). so, it's time for correct answer. (remember, this is just a side line of my game).

Let's see puzzle #9: White wins. Good luck!                                                                                                                    See a solution here: http://blog.chess.com/view/daily-puzzles-10
