I never suggested that getting in a battle of strength with someone is a good strategy, I wouldn't either even if I was stronger than my opponent. But I would use it to apply more force to my technique at the right moment. If my opponent is bigger and stronger than me, me being as strong as I possibly can would mitigate his advantage.
