ssmann, what you are referring to is called an "asian handicap" and is more prominent in soccer.

Heres how it works:

When you see the line PK, +1/2 -150:
Whatever you bet gets divided by 2 with half of the wager being at a PICK and the other half being +1/2.

For example, lets say you bet $100 on the Raiders PK, +1/2 -150

You would have $50 to win $33.33 on the Raiders PK and you would also have $50 to win $33.33 on the Raiders +1/2.

Hopefully that explains it for you.
