Butterfly sweeping your opponent at 45 degrees

From Stephan Kesting's Grapplearts.com

The 'basic' butterfly guard sweep is anything but basic. It is an extremely powerful and sophisticated attack that is difficult for your opponent to resist. In addition, this sweep has many followups and recounters, which can make life unstable and unpleasant for your opponent.

Major Sweeping Directions in the Butterfly Guard
In the butterfly guard you can sweep your opponent in every direction using different sweeps and variations. There are 4 major directions you can sweep him in:

To your right
To your left
Forwards
Backwards

There are many different sweeps and attacks from the butterfly guard, but the 'basic' butterfly sweep is probably the most important move. Here I discuss the two most important variations of the 'basic' butterfly sweep. These two variations have many similarities and a few important differences. If you are serious about developing your butterfly guard you should train both variations: depending on the situation you find yourself in you may use either sweep.

Sweeping your opponent at 45 degrees
Sweeping your opponent sideways
Both variations can be done from a variety of grips and positions. Here we will start in a common position: sitting upright with one arm under his arm (an 'underhook') and one arm over his arm (an 'overhook').

The following is a small portion of the curriculum from my DVD, "Dynamic Guard Sweeps"

Variation 1: Butterfly sweeping your opponent at 45 degrees

• Step 1

Start in the butterfly guard with your left arm under your opponent's arm (an 'underhook') and your right arm over your opponent's arm (an 'overhook').
• Step 2

Release your overhooking arm and place that hand on the floor behind you...
• Step 2 continued:

...and shift your hips to your left, away from the direction you intend to sweep him.

Note: This step allows you to shift your hips to a new angle. As you become more comfortable with this sweep you may be able to move your hips without posting your hand and/or get your opponent to move into the correct position so you don't have to shift your hips at all.

• Step 3

Replace your right overhook and fall towards your right, bringing your opponent forward at a 45 degree angle...
• Step 3 continued:

...make sure that you land on your side, and not flat on your back.
Step 4: When your shoulder hits the ground use your top (left) leg to kick your opponent's leg into the air. Simultaneously drive off the ground with your bottom (right) leg.
Step 5: Keeping your weight on the ball of your right foot, turn your hips...
Step 5 continued: ...and come to the side, pinning your opponent in a modified scarf-hold position (Kuzure Kesa Gatame in Japanese).
Step 5 alternative: Instead of going to the side, follow your opponent and end in the mount. Whether you go to the side or to mount depends on your preferences and the energy you feel from your opponent.
