Also known as: 50/50 Heel Hook · Fifty-Fifty Heel Hook
In the symmetrical 50/50 entanglement, both players hold the same weapon — the inside heel hook goes to whoever wins the hand fight and hides their own heel first.
Submission · Heel Hook · No-gi · Difficulty 4/5 · Usually learned at Purple belt
Starts from 50/50 as the attacking player → ends the match (submission).
The details that make it work
Win the hand fight FIRST: control their wrists so they cannot reach your heel while you reach theirs.
Hide your own heel — knees pinched, foot flexed and buried against their body.
Same finishing mechanics as the saddle heel hook: catch, chest rotation, slow.
Where it goes wrong
Racing to their heel with both of yours exposed; 50/50 punishes greed symmetrically.
How opponents counter it
Mirror the hand fight and stall the catch
Stand up in base to stack out of the entanglement
Is the Inside Heel Hook from 50/50 legal in competition?
