What is the main submission-defense mistake in UFC 6?

Spending all stamina on repeated transitions before the submission begins.

Should I move the stick before the escape appears?

No. Wait for the contextual escape and make one clean input.

No. Deny the next transition or recover position before trying to stand.

The best submission escape starts before the lock: keep stamina, deny the position, and do not panic into a second attack.

How to defend submissions in UFC 6: protect stamina, deny the setup, read the escape, and avoid giving the attacker a free second attempt.
