So y'all are volunteering a guy to:
play a 10AM (local) game,
get on a flight (if he can get a flight),
fly 1/3 of the way around the world,
and play a game at 7PM (local) the next day*.
I wouldn't sign off on that plan.
*His body clock is still in the old time zone. So 7PM local would be after midnight to him.
