Recently I have been working on my armbars and I need to say that the move is quite risky to pull off ingame. The use of your free hand can make or break you. I still struggle a bit with getting my left leg over the opponent. It is the part of the move that is crucial. If you overrotate, your arm might ghost through your body (which happened to me in a couple of matches), but if you underrotate you won't have enough speed to get your leg over your opponent.

In most aikido matches the opponent starts with a clap but in this match my opponent starts with an opener that leaves them quite vulnerable. I started with an opening kick with my right leg. This might make your opponent think they will be kicked on their left side.
I then lower my arms which moves my body to the ground which I have to protect from DQing with my right arm. To get enough rotation for the armbar I extend my elbow and wrist. From there I got my foot over their head and secured the armbar. When I saw I was very close to DQing and could not save it, I ungrabbed my opponent.
