Definition

Keima watari  

Here B1, which is a keima in relation to both the black+circle stones - is a tesuji for safely connecting the two groups. The move is an application of watari and dropping back. It is also known as keima watari.

Another example  

Another example: the white+circle stone connects all the white stones. See /Discussion to see the tactics behind this connection.


Example of application in a game situation

[Diagram]
Normal sequence  

After W3, B4 is normal (Even a moron connects against a peep). But what if black tries to split with B4 at W5?

[Diagram]
Alternate sequence  

B4 is a mistake, unless the top side is so valuable to Black as to compensate for the complete loss of the corner. After the sequence up to W13, white has connected under with the keima connection.

Don't forget that black can meaningfully cut at C17. If white blocks at C16, black can stand up at C18 and kill the 5 stones --gnostic?

[Diagram]
 

kb: gnostic?: You're missing W2 @ B3, then W2 and a are miai for a White connection. See the second example in Dropping Back.
