Fundamental Vectors

Master the physics of the table. Understand how pronation, cupping, and backpressure dictate the outcome of every elite supermatch.

Vector Force #1
Pronation & Rise
Pronation & Wrist Rise Mechanics
The primary rotational force. Pronation locks the opponent's wrist while the rise maintains hand height, creating a dominant leverage position.
Vector Metrics
TorqueHigh
RiseVertical
Control9.8 / 10.0
Standard: Wrist remains neutral or slightly cupped during the pronation drive.
Failure: Wrist break or loss of hand height during the initial engagement.

Vector Force #2
Cupping & Flexion
Cupping & Wrist Flexion Drive
The inward curl of the wrist. Cupping collapses the opponent's hand, forcing them into a disadvantageous position and breaking their structural integrity.
Vector Metrics
Flexion
ForceMaximal
IntegrityHigh
Standard: Deep palm-to-palm contact with maximum wrist flexion.
Failure: Wrist extension or loss of palm contact during the match.
3D diagram of backpressure and lat drag vectors
Vector Force #3
Backpressure
Backpressure & Lat Drag
The horizontal pull towards the body. Backpressure utilizes the lats and biceps to drag the opponent's hand across the table surface.
Vector Metrics
PullHorizontal
MuscleLats/Biceps
DriveExplosive
Standard: Shoulder and hand move in unison, maintaining a tight connection.
Failure: Shoulder separation or loss of connection to the hand.

Counter-Vector Protocol

To neutralize this high-hook clamp, elevate knuckles +12mm over the radial bone to expose their wrist flexor carpi to eccentric backpressure fatigue.

Filter Type:
MATCH ANALYSIS: ACTIVE|TECHNIQUES: 6
ATTACK→ COUNTER
Technique & RefOffensive ExecutionDefensive CounterImpact
High-Post Toproll
VEC-01Offensive

Rising hand and pronation to climb over the opponent's fingers and collapse their wrist.

Keep knuckles high, maintain tight cup, and drive backpressure to neutralize the rise.

CRITICAL
Wrist Collapse
Deep Hook
VEC-02Offensive

Cupping the wrist deep and driving through the side to force a bicep-dominant battle.

Keep elbow tight, fight for center, and use pronation to break the opponent's cup.

HIGH
Bicep Overload
King's Move
VEC-03Defensive

Extending the arm and using body weight to stall the opponent in a losing position.

Maintain constant side pressure and keep the opponent's hand flat to prevent recovery.

CRITICAL
Stall & Fatigue
Side Pressure
VEC-04Offensive

Using lat and shoulder drive to force the opponent's hand to the pad laterally.

Lock the shoulder, engage the lats, and fight to keep the hand in the center.

HIGH
Pad Pin
Pronation Drive
VEC-05Offensive

Rotating the wrist inward to gain leverage and force the opponent's hand open.

Supinate against the drive and keep the wrist locked to prevent hand opening.

CRITICAL
Hand Opening
Wrist Rise
VEC-06Offensive

Lifting the wrist upward to gain height and leverage over the opponent's hand.

Drive down through the knuckles and maintain a tight grip to negate the lift.
