Seam > Swing: It just had to be the WACA. Up against the stoic Cook, Ryan Harris gets it to swing back in, but the barely decipherable nip away makes the difference. Cook couldn’t possibly have played it if he knew it was coming.

Hilfenhaus gets rid of Australia’s long-time nemesis, with one that straightens marginally. If it moves too much, it’s pretty but ineffective. If it moves too little, it’s just ineffective. It must move just enough...

Scrambling the seam: If South Africa had seen Bumrah with the red ball before, they'd've been barking mad preparing a minefield. du Plessis's dismissal - an in-seamer to get him shouldering arms, only to have his stumps flattened - gave India a reason to celebrate

Playing the odds: Stuart Broad gets AB de Villiers nicking off at the Wanderers with the agent of chaos - the scrambled seam ball. The seam bowler’s unquenchable urge to toy with unpredictability makes them the foe no one could prepare for. Not even AB.

Truckloads of discipline thrown in, for a spoonful of chaos. Mohammad Abbas is elated after he gets Shaun Marsh nicking off - on the flattest of decks, in the 11th over with a trainwreck of a Kookaburra.

It’s a peach alright. Jake Ball, not of the express-pace breed, creates the illusion that he’s done Ronchi for speed with one that shoots back in after landing on the seam. That’s a rough one to get first up!

The three dimensions of chaos: Lateral movement, variable bounce and pace.
Murtagh(staring at his teammates): "I don't believe it!" Shafiq(staring at the pitch): "I don't believe it!"
