    The problem published by Joost (Probleemblad 2006) is: 1. f4 e5 2. f5 Bc5 3. f6 Se7 4. fxg7 Bf2+ 5. g8=K c5 6. a4 Qb6 7. a5+ Qb5 8. a6 Sbc6 9. axb7 Rxg8+ 10. b8=K Rxb8+. Nicolas just made a significant improvement.

    10… f5 11. b4 Rxb4 12. Kh8 Rc4 13. Kg8 and black moves same as in solution, white moves his second king around with 20. Kg8 Bxg8# at the end.

    Yes, I was about to say that the wPg2 must also be captured, but this is indeed possible… If you are able to use my ideas to find a correction Joost, maybe we could then publish it as a joint.
