Actually on 4. Nf3 black can play 4. .. Bd6, since .. Bf5 still can't be
stopped.

Of course white is ok - white is always ok. This situation just shows one of the
problems with automatically generated books. 3. cxd5 is a line that must be done
manually, game statistics won't help.

In fact, when I first saw this game, I thought that maybe this was one of
Vincent's little jokes ...
