That move generation tests are silly, because they compare apples to organges?

If you keep your attack bitboards(!) updated at all times, raw move generation
is extremely fast because part of the info is computed somewhere else. If you
compute attack info only when needed, move generation is much slower but overall
program speed is better.

What do you prefer?  :-)
