If you should choose any submission in jiu-jitsu what would it be? So now ask yourself- what is your most successful submission? The one you know anytime you get it, you will submit your opponent? Now is the tricky part. Are they the same? If yes, then go deeper: does your sweeps will open possibilities to this kind of submission? Do your passes involve using or threatening with this submission? If you are competing: do you have success applying this submission in your fights? If your first answer was “no” then think about your training. Maybe you should drill different position, or tell yourself during sparring that you will only look to this kind of submission and find ways to get it.
