What was the time control ? Blitz ?
Oh dear.
No this is on DGS. I think it was 10 days. I had plenty of time to think over my moves. (but in my defense I play a lot whilst at work when technically I am supposed to be concentrating on other matters...)

( Since you consider them "weakish", it may be constructive
to have a discussion why you think so; or maybe not...
)
True. The top left is vulnerable at 3-3, but you are right they are not at risk of dying. The bottom left is definitely the weakest group. C5 does look like a good move I hadn't realised was even possible. I think one problem I have in the beginning is I try to get stones everywhere and feel permanently vulnerable..

Both good for W.
But B has another follow-up: G5 clamp.
I think I read out the ladders which is why I felt it was safe to leave the gap there. In the game my opponent didn't push through the gap, he poked from the other side. Since I had so many of these holes he was able to use it to build up a significant central group.
The clamp is interesting. Hadn't occurred to me, but looks quite devastating!

Is this strange because it is a knights jump and hence prone to being cut? I was trying to get this group to safety quickly. If I lose the Q10 stone, I can do it but get a bit of a wall around P9-P6 or so.. That was my hope anyway..

R10.
I get the impression you feel it would be important to keep the two black groups separated. The way I saw it, both were able to live easily enough, so it wasn't worth wasting moves to keep them separate. Playing with these ideas I can see that by doing, even though Black can save both groups, he has to play more moves in order to save them - allowing me to build up stronger walls on the outside. Very interesting concept to take on board!
Variation. Did you consider other replies to the
peep variation ?
( In your second
variation (
at F15 ),
the reply
, connect at E14, is wrong. )
Hmm.. I don't see how I could kill those stones by playing at G15 which would allow black to cut at E14 which would be pretty devastating for me?
Strange. Why not hane at C8 ?
(
Important basic shape. )
The C8 hane is huge not only for points,
but because it can affect B's D13 group.
I was aiming more for outside influence so was trying to cap the top left black group as well as build up my moyo at the bottom. My ensuing move at P4 is confusing and seems to contradict my goal here. I have no idea why I played that. The hane at C8 felt a bit too aggressive for me. Perhaps that is another of my failings. I have been watching a lot of Dwyrins basics series where he encourages playing basics without killing any groups. I think I may be taking this message it bit too closely to heart.
Why. Did you do a rough count here, and then decide how to proceed ?
Here I was trying to keep the two black groups separate. I could see the four black stones at the top were vulnerable and I wanted to keep them as such..
Same note as
. What's your evaluation of the board here,
and what was your plan ?
At this point I thought the game was mine. I thought the centre of the board was all white. 100 points to me. Black had a about 45 points on the left and 30 points on the right. I felt the top was probably mine for the taking too. My plan was to keep this.
Hmm.
Did you consider any other candidates here ?
(
Important basic shape. )
So D9 would avoid an empty triangle and would threaten a move at C8. I had not considered it...
Liberties awareness is good, but what was your plan here ?
After you bumped your head into B with (
-
),
your M9 string had 3 liberties left ( not 2 ).
At this point I started to realise that black actually had quite a good chance of surviving in the middle. I was now purely focused on reducing his eye space and forgot about protecting my groups.
...up to
If you just let B live so easily, this is bad.
( Re:
,
whole-board context. )
Yes it is. I should have played more aggressively.
Is this sente or gote ?
Yes, gote. Black was alive by now.
114 (
Important basic shape. )
Was this a good shape or a bad shape?
122 Why.
Study the whole board here: where to play ?
Yes I completely failed to see the threat at F13. That cost me the game. KGS estimates that if I had played that and not messed up again I would have won by 62 points...

does protect the cut 
Still C5, I feel.
Checking your own weaknesses is good,
Locally, R10 a possibility ( depends on reading ).
Good.
