Exchange of 3rd and 4th white moves.

A graphical representation of solution a) are two isosceles impedance triangles with the hypotenuses on two different diagonals (b2-h8 and d2-h6). In the solution b) are the result two isosceles impedance triangles again, but the hypotenuses are on the same to the diagonal (b2-f6 and b2-h8).(Author)
