My son Chris has been studying jiu-jitsu for four years now. Brazilian jiu-jitsu is a form of wrestling that is also referred to as “grappling”. Its a very strenuous sport that involves close up wrestling with choke holds and submission holds.
Last weekend there was a local tournament where Chris wrestled. He won some matches and lost some matches, but the two matches he lost were to veteran black belt wrestlers. There’s a discussion forum about this weekend’s jiu-jitsu tournament with a thread where people are talking about Chris’s matches. There’s also a comment from the president of the AGC (the organization who sponsored the tournament) about how good Chris did against the more seasoned fighters.
For the purpose of the tournament, there is a point system where the wrestler gets between 2 - 4 points for gaining control, or changing from one position of control to another, as shown in this video. Chris is the one in the red shorts.
Sometimes the person who is on the bottom is the one who is in control, as shown in this video I found on the discussion thread labeled - “Chris’ guillotine choke”
If you have ever seen an Ultimate Fighting Championship (UFC) match on pay-per-view, its the jiu-jitsu guys who usually win those things. UFC is based on what is referred to as “Mixed Martial Arts” (MMA) which is a combination of grappling with punching and kicking. Chris is training for one of those fights in the fall.
