Dear Nicolas,
please find enclosed my entry - I hope it is not too late:

SPG in 9.0 moves - Christoph Fieberg - 20.09.2005 - C+
rn1qk1nr/Rp1pp1pp/8/5p2/P7/8/1PPPPPPP/1NBQKBNR w Kkq - 0 10

Visible part is that both black bishops must have
been captured on their home squares (c8, f8).
Unvisible part is the round trip of the black
King (e8-f7-e6-d6-c7-d8-e8) and the switchback of the black Queen (d8-a5-d8).

Solution:
1.a4 f5 2.Ra3 Kf7 3.Rc3 Ke6 4.Rxc7 Kd6 5.Rxc8 Qa5
6.Rxf8 Kc7 7.Rf6 Kd8 8.Ra6 Ke8 9.Rxa7 Qd8

Best regards,
Christoph
