Is there statistical analysis of which openings players play as Black when they play a certain opening as White and vice versa?
For example, is it the case that people that play 1. ..c6, often leading to a more positional game, play 1.d4 / 1.Nf3 /1.c4 more likely as White than players that answer 1. ..e5?
Is there analysis available correlating openings for Black and White?
