In 2017 Davi Ramos (2015 ADCC champion) and Augusto Frota (head of Frota Academy and 3rd degree black belt under Rodrigo Minotauro) gave a special Charity BJJ seminar to benefit the humanitarian foundation Srbi Za Srbe which helps impoverished families in Serbia. The event gathered 180 participants from various Serbian BJJ academies and all attendants give a cash donation on the day of the seminar.
In 2011 Davi Ramos broke on the international scene with an amazing performance at the Grapplers Quest championship in Las Vegas where he won the absolute division and his weight class submiting 6 of his 7 opponents and some major stars such as ADCC champs Jeff Monson (armbar) & Joao Assis (toe hold).
In this video from the seminar, he showed the Serbian Grapplers how he baited Monson into giving him the arm and grabbing his neck, grabbed around the bicep, blocked the wrist with his head and spun for a very deep armbar:
Here is the match:
