Exercise 857 from Chapter 2 Intermediate Level of The Woodpecker Method

White to Play

(a)What do you recommend for White?(This is the exercise)

(b)Evaluate 35.f6 (my question to the readers) This was my proposed solution today on my second cycle through the book.

This is my second time through the book. The reader is supposed to get faster each of the seven recommenced times through but I am getting slower.

The slow tedious process of checking solutions takes almost as long as the solving session. Today I found what I thought was an interesting attacking idea but failed to see what was wrong until I checked with an engine.
