Of course I go all out. But it doesnt make much of a difference..
My instructor is Jamie Cruz, Renzo Gracie blackbelt, Abu Dhabi competitor, Grapplers Quest Champ , Grapplers Quest Superfight champ, and Jim Miller and Dan Miller's BJJ coach.
I reguarded him the other day, and that was about as good a victory as I'll ever get.
I never get close. If you tap your instructor... time for a new instructor...
At the first place I went to, I got blue belt in less than 6 months, was tapping everyone out there, and eventually caught my instructor in a heel hook, who scolded me for cranking a leg submission. His fat ass was refusing to tap. I left, and he tried to sue me for breach of contract. I won't drop his name.
