These are separate moves with the same initial setup.

#33 Sit up Sweep from Guard 

You are laying on your back. Opponent is in your closed guard. Opponent is moving, and finally sits straight up. You place both feet on the ground, pinning opponents feet. Twist upper body in one direction (almost a minor shrimp out), and place elbow directly down on ground. Begin pushing yourself up, placing your hand in the same spot your elbow was on the ground.

Position yourself as sitting in opponents lap, all your weight pushing them down and slightly back. Wrap your free hand over opponents opposite shoulder, making a fist, and hooking under their armpit. Continue driving your hips forward into opponent, pushing them the direction your hand is on the floor, and spinning around. (If opponent places their hand back behind to catch themselves at this point, please see #34 below).

You will topple opponent over, taking the mount, and be 180 degrees around from where you started.

#34 Kimura from Guard

Do setup as described above. If opponent places hand behind them to brace the fall, sit firmly in their lap, take your hand that’s on the ground and grab their wrist supporting them (the one on the ground). Work your hips out from opponents lap and lay them face down to the ground. At this point you should be straight across their shoulders, one leg over their back, with your feet hooked on their far side, opponents arm behind their back wrapped in your arms.

Wrap arms tightly around opponents shoulder area, keeping firm grip on wrist. To finish the kimura the opponents upper arm should be straight out from his body, and 90 degrees down bent at the elbow (An upside down U for reference). Crank opponents wrist upwards while keeping the elbow close to you for the shoulder crank/kimura.
