The game of Poker has dozens of variations, but in each one, players put chips into the pot (representing money) before being dealt cards. They can then choose to check, which means they’re not betting, or raise, which means they bet more than the player before them. They can also fold, which means they give up their hand and stop betting.
A standard poker hand consists of five cards. If two players have the same hand, they tie and split any winnings evenly. A high card beats a pair, three of a kind beats two pairs and a straight beats a flush. If you have a straight, you’ll win all the chips in the pot.
After all the cards are dealt, there is a round of betting that starts with the player to the left of the dealer. Then the fifth and final card is dealt face up – this is called the river. There is another round of betting, and whoever has the best poker hand wins.
Maria Konnikova says she was drawn to the game because it’s a great way to learn about decision-making. She thinks it’s especially useful for students because they often have to make decisions under uncertainty – whether that’s what to eat for breakfast or how to pursue their careers.
Even though there’s a lot of risk involved, it’s possible to make good decisions if you understand the game’s rules. She recommends learning basic strategy, knowing how to read your opponents and using bluffing as a tool for winning.
