In sport bjj, who have you never seen pull guard? I don't think I've ever seen Jacare pull gaurd with the gi on unless he was going for a flying submission. I know he pulled guard against Marcelo in adcc and against Randy Courture, but that was a specific strategy.
Royler, Mario Sperry, I thought Terere until I saw some of his recent absolute matches. Who else? Anyone you've seen compete who never pulls guard?
It may have been a brown belt match, but I remember him pulling guard, I think it was Braulio or someone with a very good guard. He tried to pass for quite awhile, and if my memory is correct he went ahead pulled guard and won the match. I was impressed with how well rounded his game and strategies are.
