Take some heat your submissions and see what happens: In a competitive setting you want to make sure all your submissions take effect as quickly and completely as so as to ensure a decisive and convincing end to the match. In the gym however, I often encourage my students to leave a little slack in their submissions so that their partner can employ an escape – you then must that escape and back into either a reapplication of the original submission or a switch to a new one. As you gain in skill and you can extend this process further and further until you can work with elaborate chains of submission attacks upon even multiple escape attempts. Just as a cat plays with a mouse in order to practice its hunting skills – it's a good thing periodically to play with your opponent whilst locked into a submission. Don't worry if he escapes occasionally – that's all part of the . Training in this way will prepare you for elite opponents who have very well developed escape skills and it is unlikely the submission will get the breakthrough. In this situations the skill of flowing from one submission to another on an artfully defending opponent will be of great value to you.
