Establishing Deep Cross Base from Mount
The instructor demonstrates establishing a dominant mount position using a deep cross base with one hand controlling the opponent's armpit. The head is driven to the mat while the opposite hand pushes across the body to prevent the opponent's arms from crossing over. This foundational positioning creates control before transitioning to submission attempts.
High Mount Positioning with Underhooks
From the established mount, both hands obtain underhooks—one high on the neck or head area and one controlling the armpit. The instructor emphasizes keeping the forehead pointed straight and using the shoulder to maintain cross-base pressure, preventing the opponent from flipping or escaping.
Securing Mount with Knee Advancement
As pressure is applied, the top player slides the left knee forward and advances the right knee while maintaining head control. This knee advancement into the opponent's armpit prevents them from creating space and transitions toward leg drag positioning.
Creating Lateral Pressure and Compression
The instructor explains that driving laterally at an angle—rather than straight pressure—compresses the opponent more effectively into the mat. By maintaining foot drive and creating angular pressure while giving good cross-base control, the top player multiplies the effective weight distribution.
Smother Choke Finish from High Mount
From the secured high mount position with both underhooks, the instructor applies finishing pressure by bringing the shoulders together while the opponent's arms remain trapped. The smother effect occurs as the defender's own body and the top player's shoulder block the airway, with the head positioned underneath the attacker's body.
Alternative Arm Lock Finish
If the smother choke is not available, the crossed arm position creates an arm lock opportunity. By maintaining shoulder pressure between the opponent's crossed arms while controlling the head, the top player can apply an arm triangle or cross-body arm lock depending on arm positioning.
Armpit Control and Finishing Options
The key detail emphasized is ensuring the controlling hand penetrates deep into the opponent's armpit during the transition. This deep armpit control allows the top player to choose between finishing with a smother, capping the arms with the head, or rolling into a tight mount—all high-percentage finishing positions.
