Get Strong at Handicap Go
How do you use thickness to make territory - study this technique. This is because the handicap stones on the star points are influence oriented, so you must play for thickness and central influence instead of immediately going for territory. Moreover your initial advantage as Black in a handicap game makes it easy to build thickness, and since White will have weak stones, you can use your thickness to attack them while making territory.
