Solution by Henryk Kalafut:

1. Sc3 Sc6 2.Sa4 Sf6 3.d4 Sd5 4.f4 Sc3 5.d5 Sd4 6.f5 c6 7. f6 Qa5 8.fxg7 Kd8 9.g8=R Kc7 10.Rg3 Kd6 11.Rd3 Ke5 12.Bf4+ Ke4 13.Rd2 Sdxe2 14.Bg3 Sc1 15.Ba6 Sb1 16.c4 Ke3 17.Sc5

Not synonymous play from move 15.For example:

15. Sc5+ Ke3 16.Ba6 Sb1 17.c4
15. Ba6 Sb1 16.Sc5+ Ke3 17.c4
15. Ba6 Ke3 16.Sc5 Sb1 17.c4.

With BSb1 moved to f1 solution is unique:

1.d4 Sc6 2.d5 Sd4 3.Bf4 Sxe2 4.Bg3 Sc1 5.Ba6 c6 6.c4 Qa5+ 7.Sc3 Kd8 8.f4 Kc7 9.f5+ Kb6 10.f6 Kc5 11.fxg7 Sf6 12.g8=R Se4 13.Rg4 Sd2 14. Se4+ Kd4 15.Sc5+ Ke3 16.Rd4 Sf1 17.Rd2
