White: Kg1, Qb3, Rd1, Rf1, b2, b4, d5, f2, g2, h2
Black: Kg8, Qb5, Ra5, Rc5, Bg7, d6, e7, f6, g6, h7
Solution:
1. Rd3 – Rxd5
2. bxa5 – Qxd3
3. Qxd3 – Rxd3
4. a6 – Rd5
5. Ra1 (gain)

Because the historic continuation was:
5. b4 – Rd2
6. Ra1 – f5
7. a7 – Bxa1
8. a8=Q+ -Kf7
9. Qxa1 – Rd5
10. Kf1 – Re5
11. Qb2 – Ke6
12. b5 – Kd7
