One of the best things about mixed martial arts is that the sport itself is constantly evolving. There is almost always something new you can learn if you train in the sport. Complacency should be and probably is a foreign language to those training in MMA.
A particular form of MMA that requires a great deal of teaching and thinking is Brazilian jiu-jitsu. Danny Ives of Ivey League MMA in Annapolis, an affiliate of Team Lloyd Irvin in Camp Springs, held a seminar earlier this month at a MMA school in Pennsylvania.
Ives used the seminar to teach a type of guard pass in BJJ, one of what I'm sure is hundreds, if not thousands, of those types of moves in BJJ. Many people refer to BJJ as a game of human chess, which I think is pretty apropos. You have to constantly guess what your opponent is going to do then figure out how to counteract it before they actually do it.
