Many judo players do a move called a tie-up or key-lock, where they slip one arm through the opponent's bent arm, pull over the gi and "tie-up" the opponent's arm. If you want to see the whole series (and there's a LOT of it), you'll need to buy our book. Since I am working on the outline, synopsis and all that stuff publishers want, here is a guest post from Jim Pedro, Sr. today. Thanks to him and thanks to Kayla Harrison for the demonstrations (congrats on the Panam Games medal) and to Riley McIlwain for taking the photos.
Another matwork connection sequence is when you are attempting to do the
tie up, as your opponent starts to get up on her hands and knees. You
step around and get your knee in front of her chest as the other knee is
controlling her head. Then, you take your free arm and shoot it through
the arm that you were trying to tie up.
You cross-face (put your bicep into her face) and drive her to the mat
