I have to cut. Now white must settle his group on the top and I must strive to avoid making a weak group with my 3 stones on the top *and* avoid being sealed in in the corner. I am sure white can live on the top, but I don't think he can connect to K16. For example, he can't attach underneath the marked black stone:
Or, if white pushes against my M16 stone, it will make it stronger and white still isn't alive yet.
On the other hand, if white descends to Q14, I will have to defend my 2 stones. P14 is a cutting stone, so white will surely defend it.

On the other hand, if white descends to Q14, I will have to defend my 2 stones. P14 is a cutting stone, so white will surely defend it.
$$Bcm19 This is the hardest for me and the only way for white, I think. After black 21 on this board, I think white can block at r12. I'm not sure if I can push and cut at p12, this looks like it would lead to trouble for my stones on the top. On the other hand, if white spends the moves to block on the right, he leaves his top stones weak. So, if white insists on blocking on the right, I will attack the top stones. Either with a calm descent to 'a' or poking out his good shape with 'b'. I need to think on those two, should I have the opportunity to play one of them.

(below), then 5-7 is fine for me, since the white star point stone is now rendered useless.
could also be used to start a ko. In fact, that should probably be my move if white chooses this side.
and black will have miai to attack either of the two marked stones.
