Ok so a few days ago I was bored and went on youtube and watched highlights...and this came to me. This guy (don't know the name) sets up a triangle, throws the leg over but couldn't get the trapped arm over. After about 10 or so seconds of fighting it, instead of bringing the foot opposite of the trapped arm under the other knee, he brings the other foot under this opposite knee and gets the tap after he straightens the arm out. I figured this was interesting cuz I've never seen a triangle done like that, but apparently it worked in there and on my partner sparring in class. So can somebody explain this to me? http://youtube.com/watch?v=YEA6VLCIZpg It's around the 1:30 mark.
