What is Baseball Bat Choke in BJJ?

The baseball bat choke uses two hands gripping the collar in opposite directions, like holding a baseball bat. It is commonly set up from knee on belly or while passing guard. As you transition to north-south, the collar grip tightens around the neck. The baseball bat choke is famously deceptive because the grips can be established before the choke becomes apparent to the opponent. Many competitors have been caught by this sneaky submission.
