"La Donna è mobile? ... Eppur si muove!"
1st Prize Memorial V. de Barbieri
9+12. First move of the black Queen?
Solution by Henrik Juel:
bQe8 is original Pa7 promoted on a1; its first move as Q was Qa1-a2. The original bQ never moved and was captured on d8 by a wN.
Retroplay: -1... Qd8xQe8 -2.Qf8 Kc2 -3.Qe8 Bf8xNg7 -4.Nf5 g7-g6 etc.
