Sometimes you try to do something to which no specific Skill applies. In these cases, you make an Ability Check- roll 1d20 and apply the appropriate Ability modifier. The GM assigns a DC, or sets up an opposed check when two characters are engaged in a contest using one Ability against another. The character who rolls highest acts first.
In some cases, a test of one's Ability doesn't involve luck. Just as you wouldn't make a height check to see who is taller, you don't make a Strength check to see who is stronger. When two characters arm wrestle, for example, the stronger character simply wins. In the cases of identical scores, then make opposed Strength checks.
