Hello to all,
Surely this idea can be implemented in a shorter game:
1.Pe2-e3 Pd7-d5 2.Bf1-d3 Pd5-d4 3.Bd3-e4 Pd4-d3
4.Qd1-e2 Pd3xe2 5.Pd2-d4 Qd8-d6 6.Ke1-d2 Qd6xh2
7.Kd2-d3 Qh2xg1 8.Rh1-h5 Qg1-f1 9.Rh5-b5 Pe7-e5
10.Bc1-d2 Bc8-e6 11.Bd2-a5 Bf8-b4 12.Sb1-a3 Pe2-e1=S
Promotion to knight is a must; other promotions destroy game uniqueness (btw producing only one extra solution resulting from the possibility to alternate black▓s 8th and final moves).
Best wishes,
