OK, I see that book is dated 1990.
I was judging on general assesment of the position but here are some concrete games, Note that
13.Nxf5 is the correct move.
Again Black is struggling in this line, the open position of the king is a big factor, while there is usually an endgame with 2 bishops to fall back on should all else fail. I see you are tricky to convince otherwise though, so if you want to play this line, go ahead! Far be it for me to stop you

Remember though that usually a bit of independent research is more fruitful than following the "book move".
