Top Side Wrist Lock
The Top Side Wrist Lock is is a great attack on your opponent's wrist. It is seen more in Catch-Wrestling circles, as many BJJ practitioners like to go for the Key Lock in this position.
I have Caleb in the "Judo" position, Caleb pushes my chest in an effort to make space to shrimp.
I snake my right hand through Caleb's right wrist and lock my fingers around his wrist.
Using my body weight, I drive my chest to the mat. My left hand slides under Caleb's right elbow.
I grab my own right wrist with my left hand.
Switching my hips for more leverage, I pull Caleb's arm down towards his right hip as I rotate his hand and wrist down and outward, turning his thumb away from his body.
