Beginner Translation
A pin makes the other person feel stuck because their body cannot organize itself the way it wants.
What It Does
Pins help stabilize top position, slow escapes, build pressure, and create safer paths to submissions or stronger positions.
Where You See It
You see pins in side control, mount, back-control transitions, and many guard-passing situations.
Why It Matters
Pins teach that real top control comes from limiting movement on purpose, not just staying on top.
