What is Bait and Switch in BJJ?

Bait and switch is a strategic concept where you present one attack (the bait) to elicit a specific defensive reaction, then switch to a different attack that exploits that reaction. For example, threatening a kimura to get them to extend their arm, then switching to an armbar. This concept is fundamental to chain attacks in BJJ and demonstrates why understanding technique combinations is more important than knowing individual techniques in isolation.
