Life In 19x19

Please admit that it was an extremely conservative decision to edit my post.

<Sorry, plankton. I had to edit this.>

I think i have a better sequence here.
This way W makes life right away and lets B worry about what to do about the marked stones.
Either way W will be able to reinforce the left side.
$$Wcm36 ...

It looks like a hard fight to me.
If each side adopts the least compromising stance, I think it will go like this.
B can't use a keima at move 41 because even though B gets thick, W ends up with too many points.
$$Bcm41 ...

I liked the double extension sequence with W 38 connecting via atekomi at 'a' or underneath. There is ugly kikashi left at 'b' so B probably needs to spend a move to defend that also.
$$Bcm33 ...

Indeed, I can't help but wonder if white would bother with such a passive play for . I think that white can do more harm with below than black can with an unopposed .


$$Bcm31 ...

I think B will play f6 next and that W will respond.
I don't think B can nullify the marked stones with move 33.


In the first diagram, B plays the kosumi for move 33.
W can play this sequence and get a ko with a-f
B gets to play p2 also but it looks too risky.
$$Bcm31 ...

Maybe W wants to try this probe at 30 first before playing at f6.
If the position ends up like this W can have this ko sequence starting with 'a' later on.

$$Wcm30 ...

I like the 'd' option at f6 also.

Seems like a good idea to try to make b spend as many moves as possible on the bottom.

I think it makes b overconcentrated alot. there is still q2 yose that is threatening to o2 connecting m3 stones and monkey jump on bottom.

I think Black has a better answer for 3

if B connects at R6 and plays this sequence w needs to play 36 at Q2.
the cut at a is not a worry since W can play at b.
c is vital for b to live without capturing W 30.
$$Bcm27 ...

W might play 26 here to avoid having to peep at a.

well thanks for your reply even though you seem to be somewhat mistrustful of me.

I did make a mistake in my first post though. it turns out that this is more of a yose problem than a genuine life and death problem.

But there is no correct solution #2. if b had played the wrong move i think w ...
