There are those teachers who say that to learn all there is to know about passing guard, you’d be best served by consulting a good guard player. They better than anybody know what works and what doesn’t, since it’s their specialty to know how to annul the passer’s methods.
If that’s the case, there’s nobody better to teach you about passing guard than Bruno Frazatto, known for having one of the most insurmountable guards in Jiu-Jitsu today. So get some pointers from Frazatto, who just won the lightweight division at the Rickson Cup in Japan.
