After doing some X-Guard work, I'm finding that it is so easy to sweep guys that are begginer-itermediate level IF (that's a big if) they've had little experience being offensive and defensive with the x-guard. My biggest problem is after the sweep transitioning into side controls and dominant positions, but I guess that will come. The only x-guard sub I can ever get is the telephone/inverted armbar, but i know it's a sweeping guard. Anyone here use this guard from butterfly or half guard to transition into it? And general thoughts on the X-guard? Links to good techniques? Thanks guys. P.S. I have Marcelo's book.
