Hello, this is my recent game from DGS. I was white and my plan was since around move 49 to kill the middle black group, or at least run it into black's territory. My position wasn't thick enough, so in the end I didn't manage to kill it and even tough I made some points in the center it wasn't enough to win the game. Any comments welcome. :)

Is there a typo in there? :w15: at B14 is the only move.

Yes, it seems that way.

Later I was wondering about the cut at D16. I don't see any way black could get a good result if white simply cuts there. Any comments on that one? Should white cut at :w23:?

Right, I meant :w13: . It feels like white didn't get a great result in that corner, I'm just wondering if there's a better way to play it.

Thank you for the comments Bill! I like :w17: at C17. Also, forcing L16 looks good, thanks for that suggestion.

I have some questions though. :)

After :w23: at D16 and :b24: at E16 why not cut right away? How black can resist?

After :w51: at R9 what if black :b52: at R11? How should white proceed?

Which cut, michalk? Study it more closely and find the solution for yourself. :)

You missed the point of Bill's variation. Your P14 group is OK, so your original move :w51: is dame (neutral territory)
but :b52: is good for B (territory). Now think about Bill's :w51: and its meaning. :)

I mean the cut at E15. I can't see why not cut right away. I'm wondering why Bill said to leave the cut behind. Some variations:

Yes, I know P14 is OK, my plan was to attack the K17 group. Maybe M13 or some other would be a better move to do that.

Anyway, R9 looks interesting, but I'm not sure about the continuation. What if black doesn't reinforce its bottom-right corner, but attacks with R11? How should I continue? Jumping to P9 seems to give black exactly what he wants, as he can reinforce his corner now. So probably, instead of jumping, I should attack the corner somehow. But I don't see how. Could you help with that?

Sorry, I thought you were talking about another cut. :)

It's not clear the K17 group was your target yet: you also have to be careful with your G15 group,
and W has things like the H14 peep to make your G15 group heavy
while making eye-shape for K17, in sente.

For one thing, you can count and assess the global situation. You talk about B attacking,
you talk about W attacking, you talk about W jumping, you talk about B getting what he wants --
are you sure? :) R3 is still open, for example. You want to assess the global situation,
then decide what to do.

Thank you Ed for your comments, but this one is too vague to me. Consider W R9, B R11, W P9, B Q3. After this R3 is no longer open and that's what I meant by black getting what he wants. Considering global situation black is clearly leading in territory, and there isn't a lot of points for white in the center. At least that's my assessment, maybe flawed?

So considering W R9, B R11 what is a better move for white than ikken tobi? Is stealing the corner at R3 a good option? But if so, why exchange W R9 for B R11?
