Sports betting has exploded across America following the 2018 Supreme Court ruling that struck down the Professional and Amateur Sports Protection Act. What was once limited to Nevada sportsbooks is now available everywhere where state legislation allows it, bringing a whole new angle to NFL Sundays and NBA primetime games.

Making a profit from sports betting isn’t easy, but there are ways to improve your chances of doing so. One big tip is to know your teams and players really well—current form, injuries, home/away performance, and so on. Another is to keep an eye on the odds, which can change quickly. For example, if a game’s over/under line is +7.5 runs, it usually means that the bookmakers expect high scoring, which makes an under bet more attractive.

Finally, be smart about how much you wager. It’s a good idea to open a dedicated bank account and set aside money specifically for placing bets. A good rule of thumb is that each bet should represent no more than one or two percent of your total bankroll. Also, learn when to cut your losses and understand the importance of limiting your exposure.

There are a variety of sports betting strategies, from value betting to seasonal patterns. Each has its strengths and weaknesses, but it’s important to find a strategy that works best for you. Also, be sure to try different sports and markets—you may surprise yourself with what you find. If you’re a beginner, it’s a good idea to start small and increase your bets gradually until you see some profits.
