I found the following problem in the PDB:

Unto Heinonen
Die Schwalbe 128, 04/1991
Qr3nk1/p1P4p/2P5/2P4R/2P2B2/N1P5/2P2PPR/4KBN1
Proofgame in 20.0

1. a4 b5 2. axb5 g5 3. Ra5 g4 4. Na3 g3 5. hxg3 f5 6. Rh2 f4 7. gxf4 e5 8.
fxe5 d6 9. exd6 Ne7 10. dxc7 Qd3 11. exd3 Nd7 12. Qf3 Rb8 13. Qa8 Nc6 14.
bxc6 Ba6 15. Rah5 Bc4 16. dxc4 Bc5 17. d4 O-O 18. dxc5 Rf3 19. Bf4 Rc3 20.
bxc3 Nf8

With a small dual on the 8th black move (d5 works too)
