C[In handicap games, White often tries to complicate the position with this knight's jump.

However, this move is an overplay.  White cannot expect to seal Black into the corner with such scattered unconnected stones.  But Black must have a solid plan to defeat White's overplay.];

C[White has succeeded in sealing in Black.  Black's marked stones cannot push through because of a liberty shortage.

White's earlier overplay has been a success.]
