What if part of the problem was that I only had one route? Once I was in Guard I only wanted to pass. What if there were other less direct ways. Like if you are in a car and you get stuck in traffic. You can't go forward but you could turn around and try a different route.
Another problem was that I only had one position that I lead to a submission in my strategy. If I had been confident in attacks from other positions then I possibly would not have focussed so much on that one route.
One solution would be to work on simple attacks from every position.
