Nobody prepare only against crafty and the fear of bob is from traps that are
prepared also against other programs.

1.d4 is only one option(there is 1.c4,1.Nf3)
You cannot be sure that Crafty will start 1.d4 in its games.

I do not think that you can even be sure about no 1.e4

It is possible to avoid main lines in sicilian also with 1.e4(you do not have to
continue 2.Nf3 after 1.e4 c5)
