This week, we're joined by Mike Mahaffey! Mike is a second-degree black belt under Chris Haueter, best known for his Old Bastard Jiu-Jitsu style: a conservative approach built for older and less athletic grapplers. In this episode, Mike explains how to sweep from the bottom by disrupting your opponent's base instead of relying on speed or strength. Topics include: maintaining your base from the bottom, making them carry your weight, fulcrum sweeps, and the scissor and tripod sweeps.

This week, we're joined again by Jake Luigi! Jake is a jiu-jitsu analyst who made his name studying professional match footage, and he runs OutlierDB, an analytics database for grappling. In this episode, Jake lays out a three-part framework for managing risk: name the worst-case scenario, watch for the key indicators that it's coming, and only attack hard once those indicators are in your favor. Topics include: risk-reward analysis, points of control, grip fighting, terminal positions, and Goodhart's Law.

In this mini-episode, we discuss coiling, or retracting your limbs and neck. It denies access to our body's vulnerable levers and positions us to explosively generate force.

Staying coiled is a smart "default" position if you're not sure what to do. But there are times when you need to uncoil, and that is when:

#1: there's a productive reason to do so, and
#2: you can do so safely and without giving up a lever.
