C[Calmly jumping out here is the best move, which not only approaches White's center framework, but also defends against moves like A and B.

White's center may appear large, but Black must stay calm and play quiet moves like this one.]

Black has lots of solid territory, so slowly reducing the center from the outside works well. ]

    C[... White cuts off the center stone.  This result shows how handicap games are lost.

Black may have had better responses than this sequence, but the point is that plays like Black's marked stone are dangerous, especially in handicap go.]
