In the Najdorf example provided in an earlier post, I would definitely look at game statistics. The lines that score better would get my attention.

He (Moskalenko) continuously stresses the importance of creativity, trying new angles, challenging theoretical consensus and looking for dynamic ideas.
Well, there we have it, the two basic approaches to the opening. My sympathy lies with *both*. If everybody plays the one best or approved line, chess would become too easy for people with good memory and zero talent. However, you can't just play any rubbish to get them out of book, unless you are absolutely certain about the zero talent. What I think is possible is to play exactly one inferior move in the opening, to get the opponent out of book, and then switch back to playing all the best moves. The only question is how inferior can it be and still produce better statistical results than the best line. When there is a bunch of moves of about equal value (say on move one), take your pick. Other than that, you should play the best move *almost* all the time. It's that *almost* that requires experience and judgment.
Quote:Practice shows that a not too obviously inferior variation, provided that it has never been applied in tournament play, can be put to the test without too much risk, and before the "only" scientific reply has been demonstrated or published there is time to improve the variation in question and look forward to that reply to the reply which undoubtedly is to be expected soon.
Needless to say, this does not condemn all opening theory. Plenty of variations are convincing enough and have not been altered for years. But fortunately there are many methods and sub-methods about which opinions will always differ. Chess is a practical game in which, let it be said once again, our disability is just as important as our ability. If it were possible to squeeze the game into a theoretical straight-jacket chess would soon be forgotten.

I call attention to "improve the variation in question", which I take to mean the player has to put in continuous work on the creative opening choice, similar to the way the top GM has to put in continuous work on the main lines. The difference will be the intensity of the opposition, which allows us to not work quite as hard.
