Comments.Text: @InertialIgnorance: but not all novelties change opening theory, for instance if they are in lines that are considered suboptimal and the novelty doesn't change that verdict.

Comments.Text: @RemcoGerlich Yes, those are far rarer. Most novelties even at the top level tend to be difficult to face OTB, but later on an optimal reply is found. It may have already been known beforehand by the player employing the novelty too.
