    An early double 2's is often best used to make new points and/or to
    advance an anchor, so 24/22(2) 6/4(2) is a natural candidate here.
    While XG doesn't think that's the worst move in the world, it prefers
    to attack with 6/2*(2). It could lead to a blitz and it comes with
    minimal risk.
