I suspected as much. As far as I have observed, most computers are comfortable
in Colle Positions (1. d4 d5 2. Nf3 Nf6 3. e3, etc.). Part of the reason for
this is its relatively clear plan (i.e. push the pawn to e4, opening up the
position), and the fact that the piece development happens in isolation from the
opponent. Sicilians are definitely the most popular that I've seen when
defending 1. e4, though it seems odd to me, since 1. e4 e5 is called an Open
system, and symmetrical KP openings tend to heavily involve tactics and a fight
for the center.
