Well, I had the impression that most of the strong chess engines are using
bitboards today. I also thought that bitboard programs are in generally faster
in generating moves than other approaches. But I might be wrong in both cases.

But then I also know only a few non bitboard programs: Phalanx, List (4.61) ...

I don't know what Shredder + Co are actually using but assumed they are using
bitboards too.
