There has been a lot of drama lately both on and off the mat due to some new rules set by the IBJJF. The understanding of the rules in BJJ has always been a riddle for me. After years of competing both in the US and in Brazil I never really understood them other than what Ralph Gracie told me in my first 3 tournaments at white belt. "If you tap the guy you win, if you don't you don't win." That was Ralph's advice long ago. Just play your game he told me. Problem was that if you didn't tap the guy you didn't know if you won or not till the referee raised raised an arm.
