This is Sport's Illustrated's Gambling 101 - where we are teaching you the terms to help you win a little more cash and be a better bettor. We learned our bets our safe if the bet pushes, but if you don't want to play it safe that when you play the hook. A hook means that a half point is added to point spreads and game total odds. It guarantees that a wager will not be graded as a push. One side will win and one side will lose. So now that you know what a hook is- what are you waiting for- start gambling on the wild side.
