It’s important to note that the positions like the mount and the back are SO dominant that the only way to get out of them is the guy applying them making a mistake. If I escape your backmount it’s not that I’m great, it’s that you aren’t good enough at maintaining the back.
All your opponent is thinking about when you have is back is not getting submitted, he’s probably more than 4 points points behind by know and the chances of him winning the match are kind low at the moment. All he can really do is defend himself and hope you make a mistake which he can capitalize on in order to escape. It’s very hard to submit someone who’s only thinking about not getting submitted.
Why making your opponent forget about the submission isn’t always enough
Its way easier to submit someone is he isn’t thinking about getting submitted; the thought of you gaining points is a great incentive most of the time. A lot of the time though he isn’t thinking about getting submitted when he isn’t really in danger. Mentality wise the best moment to submit someone would be when he is in his closed guard not worrying about getting choked at all. But as you know it’s not a good idea to try and choke someone from inside his guard.
The position-mentality submission sweet spot!
The real sweet spot in between making your opponent forget about the submission and having the mechanical advantage of a dominant position is during the transition. In a competition setting this means that the moment just before you get your points is probably your best opportunity for a submission. And the guard pass is as good a transition as any other for submissions.
In the knee slice specifically you have a pretty mechanically sound position (you are able to use your weight and stuff) and the opponent hasn’t lost all hope of regaining his guard yet so it’s the perfect position to start going for all kinds of submissions. The most obvious ones are chokes of course.
Another great way to utilize this concept is attacking while sweeping, some of the greatest submissions happen when the guy on top is trying to defend the sweep. The triangle works great with this because every time someone posts a hand to the mat whilst in the closed guard he is opening up for some crazy triangle action.
