The pawsn are similar to naval obstacles. If there's a ship on the sea, it will sink because of the rocks.

second!!!!!!

damn! third at least!

After the first move, the puzzle is pretty straight forward, you just have to keep finding ways to keep Black in check.  (At least our Queen gets a break this time.  Interesting that it takes both a Rook and Bishop sacrifice to do the job of a Queen sacrifice.)  I like how the two pawns pull their weight.

Since Black is on the verge of Mating White, you know that you have to keep Black in Check the whole time.  The only piece, other than your Rook, that can do that is the Bishop.  But, that road seems to lead to a dead end.
