Those of you who like your football might remember the end of the 2006 World Cup where Zidane, of France, headbutts an Italian player in the chest

The relevance here is the use of the technique - when using Zu Tsuki or Ken Kudaki in this way, to the chest the opponent goes down as if he had been hit with Irimi Nage
KOTO Ryu has some techniques which use this "chest head butt" - some people question it's authenticity - so this is a great example
It works great when the opponent is too tall for a face headbutt
