I sparred again tonight with the same heavier blue belt that made me gas out on Tuesday. I thought I did much better against him tonight, making sure to not expend energy unnecessarily. Even though I couldn’t sweep him, I was able to keep him at bay with butterfly guard and even got him into single leg x briefly. I’m really starting to understand butterfly guard better, and how it works with single leg x guard. I almost think of it as the same guard, since I usually transition to single leg x from some version of butterfly guard. This means that I need to understand butterfly guard much better, so that it doesn’t become the weak link in my x guard strategy.
