Betting 101

Betting is a form of gambling where individuals risk losing money or winning something, oftentimes based on personal skill. Bettors may bet on sports, table games like poker and blackjack, or non-casino games such as bingo, lotteries, dead pool, and electronic gaming. Non-casino games often require physical effort such as bowling or skeet ball, but can also involve skill such as poker and some video games.

In betting, the goal is to make a profit over the long term by finding and placing bets that offer value. Value bets are those that have a positive expected value (EV), meaning they have a higher probability of winning than the odds indicate. Conversely, negative EV bets have a lower probability of winning than the odds indicate.

EV is a mathematical concept that accounts for all possible outcomes and their probabilities. It takes into account a bet’s odds, which represent the chances of victory, as well as the bookmaker’s business model and market behavior, which can cause prices to increase or decrease over time.

Betting lines are constantly moving, which creates opportunities to find bets that offer good value. It is impossible to stay on top of hundreds of college and professional teams and players, so it is recommended to focus on one sport or team to maximize your chances of success. The more you know about a sport, the better positioned you are to make informed bets that will lead to more wins and less losses.
