Sometimes it happens when you just try something. Ya know?
I love starting with one hand on the collar too. Keeps thier upper body under control and allows kind of a pivot point to 'swing' underneath them.
Its tough NOT to allow them to pin. It seems peoples arms naturally go for my legs. When I go butterfly even if I have an arm its easy for them to reach down. I guess they go for the knees with the gi, and the ankles no-gi.
Thinking about it, if I allow too wide a butterfly they try to pin one side and drive thier knee through. If I keep the knees close as I scoot up, they try to push them to one side. I am familiar and comfortable with people trying both. But when I am trying to get Xguard on them it becomes damn near impossible to either A)stop them B)continue with my game. I have to make defensive moves when I really want to be on offense.
When I start my sweep game, which is integral, I hit it hard. I don't like for the momentum to stop. I get hooks and I start to lift. I check thier base constantly. I am just like BAM BAM BAM BAM attack attack attack. And in those attacks people sometimes find that hole. Im looking for another ace card with the Xguard to open up more possibilities when they find those holes to swing the momentum in my favor again.
