A classic rookie mistake is making uninformed bets on the teams that you like because you think that'll make the game more interesting.

Don't just bet on your favorite teams.But there's also a more difficult to qualify aspect to wins and losses that you can only get by watching lots of sports and making educated picks. If a player is out with injury or in the middle of a slump, these things are factored into the odds-making. Often, intangibles are also taken into account when bookies make the odds.Consider the intangible, unquantifiable factors that can affect the result of a game. If you're a fan of and very familiar with the sport you're betting on, go with your gut. What are the weather conditions set to be like for the game? Who seems to have the most momentum? Who feels right in your gut? There's more to betting on a game than tangible statistics.
