What is guard recovery in BJJ?

Guard recovery is the skill of returning to guard after your opponent passes or nearly passes. Rather than giving up when someone passes your legs, you frame against them, hip escape (shrimp), and reinsert your knee or legs to reestablish guard. Good guard recovery makes you very difficult to control - even when opponents pass, you immediately threaten to recover. Key concepts: never accept side control passively, always face your opponent and create frames, use your elbow-knee connection to block mount, and shrimp explosively toward the direction that creates space. Guard recovery is what separates beginners who get pinned from advanced players who feel impossible to hold down.
