I don't know if you remember my trials and tribulation posts when I went for the Judo Shodan but in that particular competition it was all non-gi chokes and ground work. Not at all what you would expect from a aikido guy but hey it worked. Chokes are fascinating and getting into a position where they can be applied against someone who knows whats coming and does not want to get there is a study in itself. Did I mention I love chokes.
