Helpmate in 3 (a) Sa2 (b) Sa3 (c) Sb5

Solution: (a) 1.Ke5 Kd3 2.Sd6 Ge7† 3.Kd5 Sb4‡
(b) 1.Sh6 Sb1 2.Sf5 Gg5 3.Sf4 Sd2‡
(c) 1.Sf-g5 Gc3 2.Sf3 Gg3 3.Sf4 Sd6‡

Theme: Exact Echoes. The transformation (a)-(b) is reflection in the a1-h8 diagonal and (b)-(c) reflection in the 4th rank, while (a)-(c) is a 90° rotation about d4. Thus demonstrating the geometrical theorem that successive reflections about two lines at an angle are equivalent to a rotation through twice that angle.
