*	In ‘The opening (3)’, we learned that you should play the opening on a large scale. Let’s take a further look at the professional game we showed there.
*	A professional game: different strategies
	Dia. 1
	Dia. 1. From Black 1 to White 4, the players have played on the corner star points. Next, Black plays on the side with 5, but playing as in Dia. 2 is also often seen.
	Dia. 2
	Black 5 is called an approach move; it aims at hampering the development of White 4. When the opponent approaches close to one’s own stone like this, it’s best not to ignore it. Well, how should White play next?
*	Answering an approach move
	Dia. 3
	Dia. 3. White 6, a knight’s move, is an excellent answer to the approach move of 5. Another possibility is to follow Dia. 4 below.
	Dia. 4
	Dia. 4. White 6 starts a fight by playing a pincer. As it’s one space away, it’s called a one-space pincer. This may start immediate hand-to-hand fighting.
*	Extensions
	Dia. 5. In response to White 6, Black makes an extension to 7. The vague outline of a large prospective black territory can be seen.
	Dia. 5
	Instead of making the extension of 7 in Dia. 5, Black could also slide into the corner with 7 in Dia. 6. This threatens White’s territory.

	Dia. 7
	Dia. 7. Next, White makes an approach move against Black 3 on the bottom right with 8. Black makes a pincer with 9 and White jumps to 10.

	1. Play the opening on a large scale (starting in the corner). 2. When an enemy stone comes close to you, answer it.
