There were lectures, practical exercises, a massive 32-board tandem simul and a book signing for the duo's famous Chess for Life (winner of the ECF Book of the Year in 2016).
In fact the stars went on to win all of their games - a fine achievement in any simultaneous display!
What a day! Many thanks to Natasha and Matthew for travelling all the way to Teesside to put on such an inspirational show and to everyone who supported the event. Special thanks to Mike Pointon of Yarm School, who helped me on every step of the way.
There is another report and more photos here, with more to follow over the next couple of days.
