Capture stones by surrounding them |
| Let's practice the preceding section. Do you remember how many breathing spaces the white stone below has? |
|
| They are the intersections above and below and to both sides. (In this case, there are four breathing spaces.) | |
 |
|
| If you touch the stone with the mouse, the breathing spaces will appear. | |
| If all these breathing spaces are blocked up, this stone can no longer live on the board. | |
 |
|
| Capture by surrounding. | |
| You can capture a stone if you completely surround it. | |
|
The wrong way to capture a stone |
| Can you capture a stone by surrounding it the way Black has in the diagram below? | |
 |
|
| If you touch the stone with your mouse, the breathing spaces will appear. | |
| Check this out. None of the four breathing
spaces has been sealed. That means that you can't capture the White stone. |

Atari |
 |
|
| The white stone in the diagram above has only one breathing space. Black can capture it by playing just one stone. The White stone is in danger. | |
| We call this state 'atari'. | |
 |
|
| Atari is the basis of Go. Please make sure you master it. | |
