I believe that the time management of Deep Fritz is the main mistake
here.
Deep Fritz has a tendency to use less time when the score goes up and
it is a clear mistake in the time management.
This mistake in time management is typical to Fritz's versions.
If you give Deep Fritz more time to get into depth 14
it can find 25.Ne6 with no problem and I believe that white
has no problem after 25.Ne6.
