I love the kimura grip/submission. My game was and is still revolved around it. I try to get the grip from many different positions, but there are times when I think I should bail on it, or should I stick with it? If someone has a waist lock around you from your back, securing a kimura grip isn't a bad idea right? But when I'm in bottom half and I have the kimura grip, and I end up getting mounted, should I just bail? What are some other scenarios where having a kimura grip is futile?
