Like some, I have historically preferred Open Guard over closed guard. Not for the technique variance but rather because my closed guard was horrible, until recently that is. I used to have a hard time controlling my opponent and maintaining closed guard. Especially in No-Gi. I recently watched the SBGi 2009 dvd set though and had a major epiphany and am excited to be working a effective closed guard at the moment. Anybody else have something like this happen?
