In poker, like life, there is a trade off between risk and reward. Professional players seek to avoid unnecessary risk and maximize the return on their invested capital. Achieving this objective requires a Goldilocks zone of opponent perception. You want your opponents to love playing with you, but hate getting into hands with you. Achieving this mental superposition allows you to take advantage of the “fear factor” to maximize your profit.

In the game, players must ante something (the amount varies by game) in order to be dealt cards. After that, they place bets into the pot. The player with the highest hand wins the pot. In addition, some games allow players to strategically misinform each other about the strength of their hands using betting patterns and psychology.

For example, if a player has a strong hand but is afraid to show it, he may raise bets on the flop, turn and river, scaring weaker players into calling him. A well-executed bluff can also work wonders for a bad hand.

Aside from bluffing, a successful poker strategy involves extracting as much value as possible from winning hands and minimising losses on losing ones. This is called Min-Max.

Professional players are experts at extracting signalling information from their opponents. They have access to sophisticated software which allows them to build behavioral dossiers on other players and even purchase records of their opponents’ hands. They also know how to exploit the psychological weaknesses of other players, including their propensity for lying and aversion to taking risks.
