That’s the thing about life: You can do what you do but in the end, some things remain stubbornly outside your control. You can’t calculate for dumb bad luck… My reasons for getting into poker in the first place were to better understand that line between skill and luck, to learn what I could control and what I couldn’t, and here was a strongly-worded lesson if ever there were: you can’t bluff chance.

Real life is not just about modeling the mathematically optimal decisions. It’s about discerning the hidden, the uniquely human. It’s about realizing that no amount of formal modeling will ever be able to capture the vagaries and surprises of human nature.

Over and over, people would overestimate the degree of control they had over events — smart people, people who excelled at many things, people who should have known better… The more they overestimated their own skill relative to luck, the less they learned from what the environment was trying to tell them, and the worse their decisions became… The illusion of control is what prevented real control over the game from emerging — and before long, the quality of people’s decisions deteriorated. They did what worked in the past, or what they had decided would work — and failed to grasp that the circumstances had shifted so that a previously successful strategy was no longer so. People failed to see what the world was telling them when that message wasn’t one they wanted to hear. They liked being the rulers of their environment. When the environment knew more than they did — well, that was no good at all. Here was the cruel truth: we humans too often think ourselves in firm control when we are really playing by the rules of chance.

The equation of luck and skill is, at its heart, probabilistic. And a basic shortcoming of our neural wiring is that we can’t quite grasp probabilities. Statistics are completely counterintuitive: our brains are simply not cut out, evolutionarily, to understand that inherent uncertainty. There were no numbers or calculations in our early environment — just personal experience and anecdote. We didn’t learn to deal with information presented in an abstract fashion, such as tigers are incredibly rare in this part of the country, and you have a 2 percent chance of encountering one, and an even lower chance of being attacked; we learned instead to deal with brute emotions such as last night there was a tiger here and it looked pretty damn scary.

Some of us imbue probability with emotion. It becomes luck: chance that has suddenly acquired a valence, positive or negative, fortuitous or unfortunate. Good or bad luck. A lucky or unlucky break. Some of us invest luck with meaning, direction, and intent. It becomes fate, karma, kismet — chance with an agenda. It was meant to be. Some even go a step further: predestination. It was always meant to be, and any sense of control or free will we may think we have is pure illusion.

Our experiences trump everything else, but mostly, those experiences are incredibly skewed: they teach us, but they don’t teach us well. It’s why disentangling chance from skill is so difficult in everyday decisions: it’s a statistical undertaking, and one we are not normally equipped to deal with. Which brings me to poker: Used in the right way, experience can be a powerful ally in helping to understand probabilistic scenarios… The correct systematic learning process can help you unravel chance from everything else in a way that no amount of cramming numbers or studying theory ever will.

Poker, unlike quite any other game, mirrors life. It isn’t the roulette wheel of pure chance, nor is it the chess of mathematical elegance and perfect information. Like the world we inhabit, it consists of an inextricable joining of the two. Poker stands at the fulcrum that balances two oppositional forces in our lives — chance and control. Anyone can get lucky — or unlucky — at a single hand, a single game, a single tournament. One turn and you’re on top of the world — another, you are cast out, no matter your skill, training, preparation, aptitude. In the end, though, luck is a short‐term friend or foe. Skill shines through over the longer time horizon.
