How do I chain attacks together in BJJ?

Attack chaining is what separates intermediate from advanced practitioners. A single submission attempt is easy to defend because your opponent can focus all their energy on one defense. But when that defense automatically puts them in danger of a second technique, and defending that exposes a third, you create a cascading problem they cannot solve. The key is understanding action-reaction patterns. When you attack an armbar from guard, the common defense is to stack and pull the arm out. This posture breaks them down, which sets up the triangle. When they defend the triangle by posturing up, you can transition to the omoplata. Each defense feeds into the next attack. Build your chains around positions you play frequently. From mount, cross collar choke to armbar to mounted triangle. From side control, kimura to armbar to north-south choke. Write down your chains and drill them until the transitions are smooth. In rolling, commit to following the chain rather than forcing a single technique.
