Diag.: The 3-3 point invasion with keima

In addition to the hoshi (4-4, star point) there is now a keima present. White invades. Black blocks off the wider side. In this position, making the hanging connection with 6 is a safe, thick move.



White 5 above isn't the usual play - White can die here. See 4463 enclosure, for the standard ko variation. Charles Matthews

Diag.: The 3-3 point invasion with keima

This joseki most often arises when the marked keima is a response to the marked keima kakari. In this position, connecting at 6 is almost obligatory.

Diag.: White tries to kill

What happens if Black tries to kill the invasion stones with 6 here ?

Diag.: Black tries to kill

This is Black's most severe continuation. The fight will depend on the surrounding stones. Locally, White is dead: after White b, Black c, d and e are miai. Note that Black 4 cannot be played at a.



What about this?

unkx80: The result should be a ko. See Tripod Group for a more detailed discussion.



[Joonas Tyystjärvi]: Supposing that the cutting point to the right of 2 is not usable, does this work? It seems to me that after 9, white is alive - are black's moves correct? (of course, the result is locally very bad for white)
