True.
An otherwise correct, winning db line in a sharp opening that is played relatively infrequently can easily be "skewed" by inaccurate play later.
Likewise, a poor move may be followed which led to a good result purely because of the opponent mis-playing later on!
It's a case of "buyer beware" with db use. It helps if you can find a specialist in your chosen opening (preferably an IM/GM)
refine the results then look at what they play in a given situation.
For instance, in the Latvian, if you follow the black lines played by J. Hector then you won't go far wrong, as he was a specialist in the opening in the 80's & 90's. This goes along with following the white lines played by M. Zelic in the Morra gambit or Federov in the King's knight's gambit.
It also helps if you try to make an effort to understand why the moves have been played of course or else you are stranded with no map!
