Competitive Edge

An edge is an asymmetry between two opposing sides that gives one of them an outsized benefit. Size against speed, information against ignorance, preparation against improvisation: any difference you can exploit is an edge. In Edge: The Art of Ruthless Competition, a strategy is simply a system for exploiting edges.

The definition

"Competitive edge" usually gets used loosely, as a synonym for being a bit better. Edge defines it more precisely, and builds the whole book on two sentences from its introduction:

"To be more specific, a strategy is a system for exploiting unfair advantages, also known as edges."

Edge, Introduction

"An edge is an asymmetry of some kind - a difference between two opposing forces that provides an outsized benefit to one side."

Edge, Introduction

Picture a heavyweight fighting a bantamweight. The bigger fighter has size and strength; the smaller one has speed and agility. Both sides have edges, and the match is decided by who uses theirs better. Every competitive game works this way once you look for the asymmetries.

Suckers and sharp players

Because serious competition is zero-sum, walking in without an edge means walking in as someone else's edge. Edge calls that person a sucker: a competitor who expects luck, looks or talent alone to carry them. The goal of the book is the opposite, a sharp player who knows how to find edges and win. An old poker saying makes the stakes clear:

"If you look around the table and can't spot the sucker, you're the sucker."

What happens without an edge: the brawl

When neither side uses an edge, the match turns into a brawl: two competitors trading blows on equal footing, with the result a coin toss. Crowds love a slugfest. Strategists treat one as proof that something went wrong in the plan, even after a win. Edge gives a simple rule of thumb for avoiding brawls: before you engage, ask "What is my edge?" Then ask how your opponent could counter it. Repeating those two questions is the core of competitive strategy.

Edges also come with trade-offs. A big fighter who leans only on size neglects everything else, and a small fighter who leans only on speed can burn out before the finish.

"Every strength can become a weakness, and vice versa."

Edges are relative and probabilistic

An edge only counts against the person in front of you. If you're faster, start with speed. When they're weaker, find a way to use strength. Speed by itself means nothing, though: Edge borrows the difference between speed and velocity, where velocity is speed with a direction. Good edges have velocity, aimed at a specific weakness. Setting a high tempo against an opponent who can keep up just wastes energy.

Legitimate edges also never guarantee anything. Most games contain uncertainty, so an edge raises the probability of winning without making it certain. Being the best means winning more than everyone else, not winning every time.

"An edge that does guarantee success in every situation, also known as a black edge, isn't an edge at all. At that point, you're just cheating."

Edge, Play the Player: Adapt or Die

Every edge gets copied

Competitors steal whatever works. Brazilian jiu-jitsu dominated the earliest days of mixed martial arts, with Royce Gracie submitting everyone in front of him at the first UFC. As other fighters learned to defend it, jiu-jitsu became one required skill among several, and pure jiu-jitsu fighters stopped reaching the top. In boxing, George Foreman rode his punching power to the heavyweight title, then leaned on it so heavily against Muhammad Ali that Ali let him punch himself out and knocked him out.

"An edge only matters if you can apply it, and once an edge has demonstrated its power in public, you should anticipate that it may no longer be available to you."

Edge, Play the Player: Adapt or Die

Esports maps show the same cycle on a smaller scale. Defenders leave a "crazy" route lightly guarded, a clever team attacks through it, the defense adjusts, and the cycle starts over. Edge recommends attacking yourself before anyone else does: when you find a powerful edge, start planning its replacement before the returns run out.

Where edges come from

Edge organizes edges into three families, which become its three parts:

• Play the Game. Edges from understanding the game itself: losing games vs winning games, luck and variance, information, game stages and the metagame.
• Play the Player. Edges from the human across from you: VUCA, tilt, deception, and finding the strength an opponent depends on.
• Play for Blood. Edges from doing what winning requires: dropping scrub habits, learning losses, defense first and pressure.

Frequently asked questions

What is a competitive edge?

A competitive edge is an asymmetry between you and an opponent that gives you an outsized benefit: more size, more speed, better information, a better read on their habits, or a better grasp of the rules. Strategy is a system for exploiting those edges.

What does it mean to be a sucker in competition?

A sucker is someone who enters a zero-sum competition without an edge and still expects to win, usually by relying on luck, effort or talent alone. The opposite is a sharp player, who knows how to find edges and use them.

Does an edge guarantee a win?

No. Legitimate edges raise your probability of winning without making it 100 percent, because most games contain uncertainty. An edge that guarantees success in every situation is called a black edge, and it means cheating.

How do you find your edge?

Before every match, ask what your edge is against this specific opponent, then ask how they could counter it. Edges are relative: speed only matters if your opponent can't keep up, so the right edge changes depending on who you face.
