Quick question, I recall that in order to rate 2400+ players (and hence for an event to be a true Open), the time controls must be 2 hours per player over 60 moves.

• Does this include exotic timings like 110+10 or no increments like 120+0
• Is being an NA sufficient to get it Fide rated if there are titled and 2400+ players, or does the event need to have an IA? I vaguely recall that an NA is sufficient, but no norms would be possible

You can use 100 20, 105 15, as well as 110 10 and 120 0.

For 120 0, provisions of the latest incarnation of the "unable to win" rules would apply.

With all of them there's also a potential problem as to how 50 move claims should be handled if the players don't have an up to date scoresheet.

To answer the second question: yes, for an event to be FIDE rated it is sufficient for the chief arbiter to be a National Arbiter with a current FIDE licence. For title norms to be possible the chief arbiter must be at least a FIDE Arbiter (with a current licence).

On the list of arbiters (regularly updated on the FIDE website) you can see, listed by country, who is an arbiter and whether they have a current licence. There are quite a lot of IAs out there who got the title before the intermediate FA title was created and some don't have licences as they haven't been active for years.
