I tried to work on passing people’s butterfly guards again during sparring. The interesting thing is that some people don’t like for you to engage them in this way. In particular, one person managed to thwart my advances by trapping me with the De La Riva guard. The De La Riva guard can be a difficult guard to deal with. The bottom person encircles your leg with his leg in such a way as to make it easy for him to cause you to loose your balance. The worst case scenario is that he will do a move called the Berimbolo, and take your back. Several of the blue belts have this down to a science. I’m looking forward to asking about some of the moves during Thursday’s home room class.
