How do course ratings work?

But Player A's average is established on a very difficult course (say, a slope rating of 150), while Player B's average is established on a much easier course (say, a slope rating of 105). If handicaps were simply estimates of golfers' average scores, then these two players would have the same handicap index. But Player A is clearly the better golfer, and in a match between the two Player B would clearly need some strokes.
