Wow! I know this probably isn't hard for the good ones. They are hard for Chezzz
though, and it is rated appx. 2700 blitz on ICC and 2500 standard. There is a
lot of room for improvement :)

I believe this one is an error of BWTC. The mate beginning with Qh5+ listed in
the book, has a refutation. So maybe your mate in 9 is the shortest.

I think this is the same deal

True, I discovered that too. So these are also errors of BWTC. It is really full
of errors :)
