USCF has posted the complete schedule of events for SuperNationals IV. Check it out to see when your favorite GM is doing a simul or there's a lecture you wish to attend.
SuperNationals is April 3-5 in Nashville, TN. Players can still register for the event. Hotel space is running out fast! (Note: There are parents here in Southern Arizona, that have extra room reservations available if anyone is interested. Contact Enrique.)
