No I tried the correct position, it's my hash bug showing up again, I tried it
without hash and got this:

05:01 WM11 11 Nxg5+ Qfxg5 Qce4+ Nf5 Qxh5+ Qxh5 Qexf5+ Qhxf5 Qh4+ Qh5 Qxh5+ Qxh5
Rxh5+ Qfh6 Rxh6+ Kxh6 Qg5+ Kh7 Qh5+ Qh6 Qdxh6#

Don't look at the time, the job ran in the background ... so that means back to
the drawing board for me.

Wow ... 2 mistakes in one post ... well, it could have been worse I guess. :)

Buona sera ;), Leonid! See you again next year, after I've finally caught this
bug of mine ... hmmm, wonder if I could hire Heiner for that. :)
