Proof Game in 11.0
(Black just made move 11; find the gamescore)

Nice one. The issue is how white can avoid checks. The black queen has to go to its final spot as soon as possible (before the white f-pawn plays).

1.Nc3 d6
2.Nd5 Bd7
3.Nxe7 Ba4
4.Nd5 Qh4 (no check!)
5.Nc3 Qb4
6.f4 Kd7
7.f5 Kc6
8.f6 Nxf6
9.d4 (the knight on c3 bloccks the check) Ne4
10.Qd3 Nd2 (blocks the diagonal from the black queen to the white king, releasing the white knight)
11.Nb1 f5

alternative solution

1. f4 d6 2. f5 Bd7 3. f6 Ba4 4. fxe7 Kd7 5. e8=R f5 6. Re3 Qh4+ 7. Rg3 Qb4 8. Rc3 Nf6 9. d4 Ne4 10. Qd3 Nd2 11. Rc6 Kxc6

Oops, the stipulation should state "2 solutions". Well done, Mephisto2 and aginis.
