· Dia. 36. Black 1 is a move for expanding one's territory. White 2 expands White's territory, but if Black occupies the point of 3 his territory looks bigger. |

Dia. 37. Well, how about occupying the point of 2? At the same time as this expands White's territory, it reduces Black's. If Black answers at 3, White exchanges 4 for 5, blocking Black's expansion. If the moves to White 8 follow, Black's territory has been considerably reduced, compared to the previous diagram. Reducing the opponent's territory is as valuable as increasing one's own territory. |

· Dia. 38. Black 1 and 3 reduce White's territory. If Black can make White answer with 2 and 4, he makes a gain just from doing this. Next, Black jumps into the top right with 5, reducing White's territory here. |

· Dia. 39. Black jumps into White's area with 1, reducing his territory. A move reducing the opponent's territory is just as valuable as a move increasing one's own territory. White 2 also reduces Black's territory. Black reduces White's territory further with 3. |

· Dia. 40. Answering Black 1 by blocking his path with White 2 and 4 is big. Well, then, Black plays 5 to stop his top left territory being reduced. Reducing the opponent's territory is big, and protecting one's territory to stop it from being reduced is just as big. |

· Dia. 42. Jumping in with Black 1 reduces the opponent's territory. White reduces Black's territory by jumping in with 2. Black 5 is a big move, blocking White's advance. In the same way, White 8 blocks Black's advance.
· Expanding one's own territory and reducing the opponent's territory are both valuable moves. One's first priority is to think of expanding one's own territory, but if the opponent looks like getting a big territory, thinking about how to prevent this is important. Also, when one's own territory looks like being reduced, preventing this will be a good move. You win the game if your territory is bigger than the opponent's, so it's important to think about territory while you are playing. |
