I have now regained some perspective and don't feel like quite such an idiot, which is probably a good place to start. Thanks for the bouying up Ember, it sometimes feels like when I lose lots I don't want anything to do with the games and when I win lots that I just want to only play, exaggerated, but the point stands.

On game 1: -

:b23:

and

- I never even considered playing at B11, this isn't a move I've used before I don't believe and my first thought at seeing it was W would immediately cut it off at B10 but looking at it more I'm not so sure that would work normally.

:b39:

- Another move I didn't consider, it looks like it's just sitting there on its own doing nothing, but I know it aims at P18 as I have seen this before, though not sure if I've seen it directly played. At this point of the game I honestly have no strategy, while I'm not really playing at random, there's definitely some aspects of that here, albeit from moves I have seen before.

:w48:

- Give up my corner? :shock:

To be fair Guishu made this exact same point when he reviewed it

:b61:

- And the only suggestion you make for this game where I did actually consider it (and a couple of other moves in the same area), however I rejected it to take solid profit believing I wouldn't be killed on the right. Belief prooved wrong....

:w40:

- I have no idea if I responded to this well or not, but it did play out as I read it up to :b47:

, always worries me when my opponent goes along with my plan to that extent....

On game 2: -

Move 0 - This game was immediately after the first game and against the same opponent, but yes, mental fortitude had taken a blow before the game started.

:b21:

- I hadn't realised this was bad....

:b35:

- Even looking at this now when calm this is probably still the move I'd play.... W's spere of influence looks really hard to invade to me, though I'm certain it wouldn't if I knew what I was doing.

:w44:

- Yeah... by now I'd just given up hope I think....

On lunch: -

It was only a sandwich, but most of an hour away from the desk is still good

Progress Report: -

Tsumego: Started reading Graded Go Problems for Beginners IV again
Games Reviewed: 3 lost games (sort of)
Other: Continued reading The Endgame

Something about this tsumego book doesn't like me, I'm 164 problems in and at 44 answers wrong, still persevere through it enough times and I should pick up the patterns :rambo:

Three games reviewed this week, one of them on ASR League where I can reasonably confidently point to a single move about 50 moves into the game that lost me the game, especially as I tried to save everything. Lesson from this game: Do *not* invite splitting attacks against yourself when playing a 2D in an even game!

The second was a lost game which was kindly reviewed by Ember and also another person who joined the game I put in in the KTL room, though we stopped the review by about move 125ish as the game was already over at that point really. Main lesson from this one: Don't make so many weak groups, they get me into far too much trouble.

The final game was the reason I put sort of in the summary.... I resigned a game I was ~20 points ahead in. I lost a group in endgame and a quick look at the board made me think I had lost so I resigned, only after that did I hit score estimator to see how much I lost by, and then noticed I hadn't lost. I also made a mistake in defending which would have turned my group from needing a hopeless ko to live into just outright life. Lesson: COUNT!

The Endgame I am basically stuck on Chapter 2; Counting. I am not going to truly go past this point until I get it right. Simpler cases I can work out, albeit needing far more time than I probably should, but once I start to need to take multiple possible follow ups into account things get hazy (e.g. hane onto 2nd line leaving either player with a possible play on 1st line afterwards).

And here's the game which Ember reviewed (thanks again!): -

Move 130: I actually forgot my group at H10 existed.... :oops:

Edit: Forgot to link the SGF file -_-

Peter, sorry, I thought you were :black:

.

did you consider hane D14 ?
:b21:

did you consider o16 ?
:b29:

P3 turn, big sente.
:w30:

o3 jump.

small, slow, gote. The right side so big.
:b59:

floater.

strange shape; either connect or tiger's mouth.
:b67:

should reply at o11.
:b69:

W tenuki, so you play o11 yourself.
( Follow-up is S9, not R9 ! )

EdLee · Post by **EdLee** » Sun Jun 08, 2014 11:23 am

did you consider C14 hane ?
( Both :b7:

and

missed the first feeling hane. )
:w14:

good result for W.
:w26:

push at P3 first, otherwise after you connect, B turns at P3 in sente.
:b47:

this result is a disaster for W.
( Before :w38:

hane you must read very carefully. )
:w42:

connect N4 first ?
:b51:

and

both gote; both of you confused by junk food ( N2 ).
:w58:

maybe jump to P11 directly ? B lower right too thick.
:w68:

basic shape is extend o11.
:black:

111 result bad for W.

Big problems remain with basic shapes, contact fights:
good result at :w14:

, but subsequent contact fights
ended up badly for W.

PeterN · Post by **PeterN** » Sun Jun 08, 2014 1:27 pm

Yeah, this game wasn't one of my finest moments.

:w8:

- No, I didn't consider it and even if someone had said it I still think I'd have rejected it (unless I saw their rank was higher than mine), pushing through that one space jump just looks so right.

:w26:

- Wasn't quite sure how to deal with this area, I know 3-4 point josekis poorly enough, let alone 5-4 point ones, I will try to remember this.

:b47:

- This whole sequence started with a misread and ended with me simply salvaging what little I could from it, which wasn't much.

:w52:

- I was trying to shore up my group on the left and expecting him to capture my three stones. I shouldn't have expected that....

:w58:

- Didn't realise this was bad as the group managed to live, despite :w76:

being another misread.

:w68:

- Believed the group could live and wanted to take some points.

:black:

111 - No argument there, we thought pulling back to defend at the start of this whole sequence would have been the best option when reviewing it.

Peter, you are right about :w8:

, it's the correct move because afterwards,
B has two cuts. Conversely, if B gets the same wedge first,
then it is W who ends up with two cuts.
This is why :b7:

attach at 3-3 is not joseki.

Progress Report: -

Tsumego: None
Games Reviewed: 4 lost games
Other: Played through six games from Invincible

Got lazy on the tsumego this week and didn't do anything at all :oops:

Reviewed four lost games, two on the ASR League, and two offline, one of which I just got completely flummoxed by my opponent and still have little idea what happened.

Took a break from The Endgame and played through six games from Invincible this week, doubt these really help, but it's fun to do it sometimes. And even though I'm not far in the opening is beginning to look strangely familiar on each game.

Also learnt playing go when you go to sleep at 2am after watching football and still waking up normal time leads to not noticing groups in atari.... :oops:

Game which flummoxed me: -

He just seemed to play everywhere at once and I felt like I was on the backfoot for a significant portion of the game.

Hi Peter,

you know the joseki is C9. You tenuki, so you must know you owe W a move locally, otherwise you have a weak group.
:b15:

Bad habit/bad basics. Why is this bad ?
:b19:

if you already have the C9 joseki extension, then this a correct local reply to :w18:

(like

.) But you don't have C9, so this move is very slow and heavy -- W can attack your heavy group with :white:

C9 himself, etc.
:b39:

Bad habit/bad basics. G8 is a shared vital point.
:b47:

Bad habit/bad basics (similar to :b39:

). If you play the :b45:

push, you must then cut at E15. The saying is "push and cut," not "push and retreat" or "push and push more from behind." If you don't plan on cutting, or you cannot cut at all, then don't push to begin with -- just play E17 ( :b47:

) directly.
:b61:

joseki is Q15, extend. Numerous existing threads and discussions about this :b61:

hane. Good to study the joseki Q15, and to study the :b61:

hane variations.
:b63:

Mistake, after the :b61:

hane. You have to connect at Q15 instead. This is one of the important things to learn about the :b61:

hane variation.
:w64:

After this cut, one of your two B groups here will die. This is why :b63:

is a mistake and why you have to connect at Q15 instead.
:w68:

W gets a better result here than joseki. Study the joseki: Q15 for :b61:

, compare the two local results.
:b85:

Bad habit/bad basics.
:b87:

Locally, M10 more efficient.
:b95:

Bad habit/bad basics. Study these bad habits: :b39:

,

, etc.

105 You got gote here entirely of your own doing. You gave W sente.

At these levels, a significant portion of the problems lies in our basics.
Once again: basic shapes, contact fights.

Hi Ed,

I was W in this game

Though I'll still go over these comments when I have some time.

Hi Peter, sorry.

PeterN · Post by **PeterN** » Tue Jun 17, 2014 2:54 pm

Thanks for the comments Ed.

:w10:

- Never even considered tenuki here, I think the whole game it felt like I was responding for a large portion. Probably a reason why I virtually never see double approaches in my games.

:w12:

- I like your varient a lot better, I got attack happy though.

:w20:

- Yet another move I hadn't considered, first thing on my mind was don't get surrounded. :sad:

- And then promptly forgot about it.

:w36:

- I suspect I do this a lot and looking at it while disregarding your comment it looks completely natural to me. Bad habit identified. :tmbup:

- Not something you commented on, but I really need to learn these josekis, I am getting into far too much trouble with approaching 3-4 stones.

:w84:

-

. Not much else I can say on this.

Progress Report: -

Tsumego: Continued reading Graded Go Problems for Beginners IV
Games Reviewed: None
Other: None

Not done an awful lot this week, not even played that many games, despite England being out of the World Cup still been watching some of the games.

On tsumego I'm now at 307 problems done and 99 of those wrong, almost the same rate wrong as the first lot I went through in this book the previous week oddly. Definitely noticing I'm terrible at the problems for making ko, doubt I'm getting even 1 in 10 of those right!

One of the few games I did play this week was the following one, a great lesson on pay attention and count liberties properly. So should not have won this game....
