First, why does the Kan score significantly higher than the Taimanov, despite many claiming that the Kan is more passive (which is negative?) than the Taimanov? Surely, if there is more counterplay for the Taimanov, that means that it would be higher scoring for Black than in the Kan.
Second, in the Kan, how should someone choose between developing the queen's knight to c6 or d7 (since it's supposed to be one of the reasons it is preferred by some over the Taimanov)?
