(Solution by Nikolai Beluhov)

The convention here is that pawns may promote to, and only to, the types of fairy pieces present in the diagram position. Writing G for Grasshopper and S for Knightrider, the solutions are:

(a) Retroplay: 1. Qa3:Gb3+ h2-h1N 2. g4 h3 3. g3 g4:Nh3 4. Nf4 g5 6. Ne6 g6 7. Nc5 Ge6 8. Nb3+ Ge8 9. h5 Ge3 10. h4 Gg1 11. h3 g2-g1G 12. h2 f3:Gg2 13. Gc6 f4 14. Ga8 f5 15. a7-a8G f6 16. a6 f7 17. a5 a6:Rb5 ...

The last 34 single moves are precisely determined. Ceriani-Frolkin theme - a black and a white Grasshopper.

(b) Retroplay: 1. Qa3:Sb3+ h2-h1N 2. g4 h3 3. g3 g4:Nh3 4. Nf4 g5 6. Ne6 g6 7. Nc5 Sa5 8. Nb3+ Sc6 9. h5 Se5 10. h4 Sg1 11. h3 g2-g1S 12. h2 f3:Sg2 13.Se6 f4 14. Sa8 f5 15. a7-a8S f6 16. a6 f7 17. a5 a6:Rb5 ...

The last 34 single moves are precisely determined. Ceriani-Frolkin theme - a black and a white Knightrider.
