The question is too general to have a simple answer, I think.  It all depends
on how your attack tables look, and how the rest of your data structures work.
Personally, I have always calculated them from scratch at every node (not
terribly expensive for me, because the rest of my engine is also dead slow).

In my new engine, I am trying to avoid calculating the complete attack tables.
Instead, I will try to calculate all attacks to a single square when needed.
I think it should be possible to do this rather quickly on my 0x88 board, but
it is still to early to say how well it will work.
