De-forking Quercus dentata

After taking charge of my father's oak collection in 2009, I noticed that several of the trees had forks in the trunks and hence co-dominant stems. Having no knowledge of these matters, I consulted Guy Sternberg, who I had visited in Starhill Arboretum in 2010, seeking guidance. I sent him a photograph of some of the oaks in question, and he replied with suggestions on how to tackle one of the worst cases: a Quercus dentata planted out in 1998. Guy described this tree as having a "Very Bad Fork" and prescribed a course of subordination or suppression of the weak secondary leader.
