Today I started trying to teach myself how to use the lockdown.
I'm not overly sure if I'm doing it right. If I take a half guard trapping their right leg, do I bend my left leg across and lock the foot under my right knee?
Then do I hook my right foot under their leg so that the sole of my foot is pointing to the outside?
It worked for me this way at first and I was able to set up the oldschool sweep keeping the lockdown quite a few times(or rather what I think is the lockdown). But after a while the dude got a bit wise and started managing to pull his leg through to a 1/4 guard where I only had the lower half of his leg trapped.
Am I doing the lockdown correctly?
And if I am, What points should I remember for keeping the guys leg tied up and stop him from freeing it?
