To win betting on sports, you must familiarize yourself with different betting markets. Professional bettors can find value in all areas of a game on the best online sportsbooks, which means they need to be able to target different markets on sports betting sites for different games.
To pick the best bets, you still need to consider odds and choose events where your combined selections have the best chance of winning in relation to your odds, rather than simply supporting all of the selections you think might win.
