I am confused!
Hi Bill,
March 27 - April 11 are the correct dates. We have corrected the other page. Thanks for alerting us to this!
Thanks, Franc. My blindfold simultaneous tour of Hungary begins in Kecskemét on the 14th, and I’d have hated to turn down my invitation to play in my first US Championship.
+1 - my vote for the 2017 blindfold brilliancy prize for posts.
Hi Bill,
It turns out that the schedule that was posted was correct for players and arbiters. That is, the 27th is the arrival date and April 11 is the departure date. The Opening Ceremony is on March 28 and the Closing Ceremony, and tie-breaks, if needed, will be on April 10. So, we have corrected the dates on the website to read: March 28 - April 10 (First game on March 29th).
No problem with your invitation. I had alerted the organizers that you would not be available because of your simul tour in Hungary, but I told them that now you are available. 
Thanks again!
