Puzzle Challenge 3

The last Puzzle Challenge for the term! I reused Monday's puzzle since only two people participated on Monday.

Here's the puzzle:



White to Play and Mate in 6. Assume that Black will always make the move that prolongs the mate for as long as possible. There is a unique fastest solution and that is 6 moves.
