In 1996 the late Shawn Walsh, head coach of the University Maine ice hockey team, instructed Mark in hockey strategy. This fragment is one of the hundreds of play sketches Shawn made on pages from a hockey rule book.

This material was useful in the development of AI strategy for Mark's and MBL Research's subsequent hockey games.
