I think it is. In my program I check for special moves (ep and castle) and do a
full (slow) checkdetection else I do the fast one.

You can also use this for your own checkdetection (after your own move). If
not(special_move) and ( I wasn't in check to start with ) do fast checkdetection
else do slow one.
