Closed Guard Entries: Shoulder Crunch Armbar Attack

Executing a shoulder crunch armbar attack from closed guard:

1. Start by establishing a shoulder crunch from the closed guard to prompt your opponent to pull away.
2. As your opponent pulls away, cut your angle to the opposite side and scoop their leg while ensuring your knee is in front of their shoulder and your shin grinds across their face.
3. Transition into an armbar position, expecting the opponent to defend by stacking and attempting to pull their arm out.
4. Anticipate their defense by bringing their hips in, which will force them to posture up, giving you the opportunity to attack.
5. Chop at their leg and force their weight forward, using their reaction to extract their leg and transition to attacking the other leg.
6. When your opponent pulls away, wrap around the inside of their arm, catch the elbow, and pinch your arm down to maintain a strong grip.
7. As they continue to pull away, focus on keeping your knee inside and transitioning to an armbar position.
8. Stay tight with your knee in front of their shoulder and swing your leg over to finalize the armbar.
9. If they posture to defend the armbar, use this to enter a good K guard position.
10. Off-balance your opponent using the threat of the upper body attack to transition to attacking the lower body, both on the same side and the far side.
11. Force your opponent's hips in to create the posture needed to get underneath them.
12. Use the shoulder crunch to set up various attacks, including controlling the head and pulling them forward as they attempt to pull away.
13. If they sit back while pulling away, grab the inside of their arm to stay attached and switch sides to attack the far leg with K guard.

This sequence leverages the shoulder crunch to create a series of attack opportunities, transitioning from upper body to lower body control and using the opponent's defensive reactions to your advantage.
