;AW[hs]C[Hi! We're going to look at nets. This is one of the most basic tactics with which you can capture enemy stones. When we learn Go, we first need to master the ladder and the net. If you can capture with either a net or a ladder, a net is generally better. If you capture stones in a ladder, your opponent will be able to play a ladder breaker. But when you play a net, there's no such possibility. So you need to practice dealing with situations where you can use a net. Let's look at this problem. Earlier on, Black haned and connected. These were endgame moves. But White played elsewhere, thinking that there was no aji in this area. But that was too much, so Black should punish White.]
;B[hr]C[First of all, Black should cut here.]

;W[gr]C[White will atari and capture the black stone. It's a failure.]

(;B[er]C[Black can capture white in a net. Now White's in big trouble.]
;W[es]
;B[ds]C[No matter where White plays, white can't escape. So that's how Black captures the white stones.]

;W[es]
;B[dr]C[Does this net work?]
(;W[er]C[No. White can easily connect with any move. We often face these situations unexpectedly. If you're familiar with this kind of net, it can be devastating..is kind of net, it can be devastating.]

;AW[nn]C[Here's a problem. White's cut separates black. If Black does not capture this white stone, the two black stones at the bottom will be in trouble. Because of the two white stones to the left, White's position looks strong. But you shouldn't let the shape deceive you. How can Black capture this white stone?]
(;B[op]C[This atari is a good start. ]
;W[po]C[When White stretches, what can Black do now?]
;B[on]C[By attaching here, Black makes a stylish net.]
;W[oo]C[If white tries to escape, ]
;B[no]C[Black can atari and capture these white stones. It may seem obvious and easy, because I'm showing you this problem now. But this combination is often overlooked in actual games. It's easy to capture your opponent's stones in a net. But you have to read several moves ahead, which can sometimes be complicated. So you should also practice combinations like this. Many situations require such a combination. Because of that, you should practice until you remember the patterns in which you can make a net.]
