Knee On Belly to Kimura Attack

Starting from knee on belly position on bottom's right side
Person on bottom puts their hand on my knee to push away.

Step 1: I use my right arm (arm closes to their hip) and hold their wrist down to their hip
Step 2: I bring my posted left leg around B's head while dropping to my knees and securing a kimura grip on the trapped wrist
The next steps depend on where B's arm is situated.
If the arm is stuck in between my legs, I let go of the kimura grip and secure the arm with the gi or the belt. Then I use my free arm to pull B's trapped arm to eliminate the space and go back to finish the kimura. If B's arm isn't trapped between my legs and is just outside, I clamp my legs to their head and finish the kimura.
