Top Positional Control is normally always over submission attempts when it comes to Jiu-Jitsu. This is a general rule and should be followed by the newer grappler and experienced grappler alike.
Add in pressure to the mix and your top positional control just became a more effective tool against your opponent. Again learning this takes time, so for now understanding how to simply hold a position should be of the utmost importance.
Though top positional control should be learned in the beginning, as one gets better don’t become stubborn over only holding a position. Learn to successfully progress forward by failing, and then doing it again. Eventually you’ll learn that if it’s not working, or you lose the position, then moving onto something else is the better option.
“Submission-focused” players, though not necessarily bad, tend to give up control of their opponent and allow space to form between the two. This can be detrimental during a roll causing one to lose position, or worse put one in a disadvantageous position.
The more one focuses on dominant top positional control, the more one sees submission opportunities show up courtesy of their frustrated opponent. Use your top positional control to “make” the opponent give you something that they wouldn’t otherwise do.
This is key.
Learn. Drill. Roll. TRANSFORM!
