Shesterkin, Rykov, Barron and Keane made an appearance at the end which was pretty cool except that they cut the event at least one hour short IMO.
P.S. It bothers me how they mispronounce Rykov’s name. It’s not “Rai-kov”, if anything it’s closer to “Rick-off” with tongue pushed back/down to help make it a more throaty sound.
