Now you know that diagonally connected stones can be cut by the opponent. Before being cut, you can defend yourself.
If white plays a cut on F6 here, two stones (F7 and E6) will be in danger.
That's why black must play defensively before the cut.
This is a connection move.
Here, after F6, black connects its stones tightly.
This is a direct connection . White will no longer be able to cut them.
Below you can see an indirect connection.
White can of course play F6 , but he will be killed instantly with F5 . Please try to analyze him on the board.
The stones are virtually connected.
Play freely on the board.
These types of indirect connections are played more elaborate than direct connections.
If you know exactly when to make an indirect connection, you’re not a beginner anymore, that’s for sure.
In the picture, black has two cutoff points at E5 and F4.
You may wonder which one will be cut... There is a good move which defends both weak points simultaneously!
Please make a move in F5. Now White can't play neither in E5 nor in F4. That's why F5 is a indirect connection to both.
Because of the form, this connection is called a trumpet connection.
