I think i did pretty well this game, but still requesting review. I'm trying to upload most of the games that I play so I get something out of it.

If I could get the tips on killing it would be appreciated. Every stone that I go after ends up living most of the time.

I am black.


Note: Okay... not sure what is going on with the embed... it looks all funny too me and not working correctly. I do have the .sgf file attached though.

Hi negapesuo, this a personal preference:
I prefer to use the [SGF] tags and include the explicit SGF text directly here.
This removes any middle-layer and dependency on an external website.
( For Youtube or other websites, we have no choice but to use the link;
but with SGF, we don't need any external link,
we can have a 100% self-contained post right here, so I prefer it. :) )
In post 1, you used the sgf-problem tags.

Hi negapesuo,

:w7:, :b8: Slow, small. :w7: is slow; no need to reply.
( Follow-itis. ) Should tenuki on :b8: .
( From the recent AlphaGo games, AG rarely played even :w5: ;
AG tended to tenuki on :w5: .
The rare cases when AG played :w5: was when it had to do W in danger. )
:w9: B has 2 cuts here, B17 and C16. Which is important to fix ?
Study the local shape.

:b10: C16.

:b12: This is because of :b10: . If :b10: was at C16,
then you could resist with the hane E15.
But because :b10: is at B16, you are forced to pull back here.
Go back and study the local shape at :b9: .
Notice that whether :b10: is at B17 or C16,
W cannot gain any eyespace there:
after :b10: at C16, if W hanes B19, B simply replies at A18 --
W has not gained any eyespace at the corner.
That's why you want :b10: at C16.

:b26: Did you also consider B R15, W Q14, R o17 ?

:b28: Very strange. Both W and your Q16 stone are not settled:
R17 becomes a big shared point. Whoever gets R17 first becomes stronger
and makes the opponent weaker. Also, W's F17 group has good shape and is nicely settled (thanks partially to :b10: ), so W F17 is not your target.
No reason to give up R17.

:w29: Too much. ( Follow-itis. ) W should be happy to take R17 himself.

:b40: You got a good result here because W hurt himself starting with :w29: .

:b42: In this case, this hane is big, because W is not settled.
( Different from :b8: .)

:w45: Slow (and heavy?) W needs to play faster, more lightly.
( eg. P13, Q12, S12, etc. )

:b50: Wasted move. ( Follow-itis. ) Why ? What is the local status of W ?
Locally, W is dead shape, even if W plays first in the corner.
:b52: This is a Pass. ( Follow-itis. ) Why ?
Locally, T14 removes W's only eye.
If you want to close W (to kill it), it requires more reading.
( I'm not what's the best move here. Neighborhood of o13... )

:b56: ( Follow-itis. ) Currently a big, recurring problem in your moves. Slow, unnecessary moves (passes). Why do you need :b56: ?

:b66: Very big. (Re: :b28: )

:b68: B2. B2 is big because W is not settled. (Compare: :b8:, :b42: )

:w69: B has shape problems here (C4).
This is because you missed B2, and :b68: made bad shape for yourself.

:b70: - :w71: Compare the local shape if :b68: at B2.

:b74: If you want to kill W, G4 is a candidate to read.

:b78: Wasted move. Why ? You're already connected after :b76: .

Slow or unnecessary moves up to here: :b8:, :b50:, :b52:, :b56:, :b78: ( > 10% )

:black: 100 If you atari at K8, W connects, then you can play K9,
getting ahead of W.

Thank Ed - Yes, I see what you are talking about when you say i have a lot of wasted moves. The number of sente that I could get if I didn't waste moves could probably move me up an entire stone. I often take time to make "precautionary moves" because I don't trust my reading... Thanks for the insightful tips. The B100 move was especially cool.
