However the route shown in his book is faulty : 26-23 5-9 22-18 13-17 18-15 11x27 32x23 17-22(A) 25x18 8-11 20-16 11x20 18-15 which leads to the following white win position

(A) However instead of 17-22 pitch black can draw by 8-11 23-18 14x23 21x7 23-26 7-3 9-14 25-21 26-31 leading to the following draw position (white to play)

Go back to the beginning though and play 32-28 to win this position
