The Kent Open is my competition.
It is run by Carlson Gracie Revolution Team, the first year we ran the competition for 450 competitors in 1, YES, 1 day. Last year we had a more relaxed atmosphere and did just under that number in 2 days.
This year we are again running the event over 2 days, it has changed it name to the English Open. Info and registration here
HOME - 2010 English BJJ Open
Without seeing the fight that we are talking about, I cannot give a definitive answer, however there are 2 possible reasons.
a) We did use non standard (hrizontal stripes/not vertical), green and yellow belts for those same colour gi scenarios. maybe an orange Judo belt found it way into the bag? it is primarily a massive judo centre after all
or
b) It was a juveniles match where a white belt, was fighting a graded yet still juvenile competitor.
We do have juvenile competitors at the comps, ranging from 6 or 7 upto under 18s.
Hope this helps!
OSSSSSSSSSS!
