Chapter 9
Chapter 9 — "Pressure — Keep a Blue Head"
TL;DR: Under pressure, the brain has two states — Red Head (panic, tunnel vision) or Blue Head (clarity, presence). Train the switch.

Summary: Chapter nine introduces the book's single most-quoted mental model: Red Head / Blue Head. Developed with mental-skills coach Gilbert Enoka and forensic psychiatrist Ceri Evans, it gives players a shared vocabulary for the moments when a Test match tilts on a single decision. A Red Head is heated, hijacked, narrow, reactive. A Blue Head is cool, on-task, wide, clear. Kerr explains the techniques players use to flip themselves blue: physical triggers (stamping a foot, splashing water), mental "maps" (a visualized routine that re-anchors attention), and language cues (the team mantra used as a reset). The chapter is built around Richie McCaw's pre-match notebook, where he writes the letters "K.B.H." — Keep a Blue Head — across the top of the page. Kerr argues the framework is exportable: surgeons, fighter pilots, and CEOs need the same switch. The chapter's defining visual is a single profile of a head, the cranium split into a turbulent dark side and a calm cool side — diagrammatic editorial illustration.
Key scenes:
- A close-up of a leather-bound notebook with hand-written letters "K.B.H." across the top of an open page
- A player splashing water on his face at a sideline trough, the moment of the reset
- A diagrammatic head split into red-turbulent and blue-calm hemispheres — the chapter's signature image
- A field shot of a captain pausing inside a chaotic ruck, eyes deliberately closed for a single beat
Characters present: Richie McCaw, Gilbert Enoka, Ceri Evans (forensic psychiatrist consultant), anonymous players executing the reset, James Kerr (narrator)
Locations / settings:
- A team-room desk with a single notebook in a pool of lamp-light
- A sideline water trough with stadium darkness behind it
- A stadium ruck — chaos in deep blur, one figure in sharp focus
- A diagrammatic black field for the head-split illustration
Visual motifs: a head in profile split into turbulent dark and clean light hemispheres; the letters "K.B.H." hand-lettered on a page; a hand cupping water; a pair of closed eyes inside a chaotic blur — the eye of the storm
Emotional tone: clinical, composed, focused, intentional
Confidence: high — Red Head/Blue Head is the single most-cited concept in the book and is repeated across virtually every secondary source.
