makes sense
Idk if I agree.
Might be some shape issues. The bamboo joint threatens to surround the corner or take the base of the two white stones.
Agree this looks great for black.
forces white to strengthen himself without really strengthening black. Jumping out threatens surrounding either the corner or capping the white group.
You can see the 3-3 invasion really hurt the black group at G3
I think this move is small. All the white groups here are alive. There are a lot of big points left to take. Enclosure. Or star point on the top.
Maybe hane on top first. The two stones aren't very important because the white groups are alive and connected.
Compare in game with R15 at

It looks like black is searching for forcing moves which is good because sente is nice. But not all forcing moves are good. For example your variation at is a forcing move (atari) but it gains nothing for black. All it does is lose a liberty. So it's not very good.

Instead of directly forcing white with moves like I think black can start looking for moves like jumping out at It indirectly forces white because it threatens two sides.

Happy New Year!

Is black in the down-left conner can be killed?

Hi sliderser, see Bill's notes and variations at , and 194.

I added a variation on move for discussion. What do you think about that variation?

Doesn't quite work, I think. Black connect at O4 and then if white cuts at O6 black can atari at N6 and then capture the Q7 stone.

I edited your suggestion together with some followups in my above posting, but I'm not yet fully convinced. After white blocks at N5 I cannot see a clear way for black how to capture O6,O7.
