Hi negapesuo,

:w7:

Slow, small. :w7:

is slow; no need to reply.
( Follow-itis. ) Should tenuki on :b8:

B has 2 cuts here, B17 and C16. Which is important to fix ?
Study the local shape.

:b10:

C16.

This is because of :b10:

. If

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.

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:

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

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 ?

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:

Very big. (Re: :b28:

)

B2. B2 is big because W is not settled. (Compare: :b8:

)

B has shape problems here (C4).
This is because you missed B2, and :b68:

made bad shape for yourself.

:b70:

Compare the local shape if :b68:

at B2.

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:

( > 10% )

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

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.

Post subject:	Re:
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.
