>Precision is a murky concept in chess because it is not a solved game it's ironically also a murky concept for the opposite reason. In some openings the analysis of GM's goes so deep that they can fairly often play almost exclusively computer-aided prep. There's a big difference between a 40-move game in that kind of theoretical position vs off-beat games. So you might have a very precise, narrow, theoretical repertoire but that's not the same as playing strength because your opponents can prepare. What really matters is more something like precision under uncertainty.
