Wow, thats weird. You would think it would just be the usual "invalid fen".
Ah - so the Nc3 is not there to be taken by the rook in this variation. And its an easier mate in 8 to have a chance of spotting since most of the moves are forced checks by black to stop the mate in 1.

is discussed on page 65 of the Yugoslav Attack by Miles & Moscow.
They look at 21.g5 and 21.Rh2.
They don't look at the Nf5 idea promoting someone to write that perhaps
Miles saw it and was saving it ...[text shortened]... xc3 3. bxc3 Nf6 4. Bxg7 Kxg7 5. Qh6+ Kh8 6. Nf5 Rg8 7.Qxh7+ Nxh7 8. Rxh7+ Kxh7 9. Rh1[/pgn]
That is a pretty mate!
You said - (Black must play Bxf5 instead of Rg8)
Doesn't Bxf5 lead to g5 and mate anyway as in other lines, or am I missing the point and it was just the fantastic double sac you were pointing out.
