Finally played a game.

handicap games still feel uncomfortable.

got a lot of thickness didn;'t really know what to do with it.

couldn't even tell if i was ahead or not.



kgs is inflating my rank, which is kinda cool haha

a few different situations involving the 3 space high-low extension.

my most common move is to just attach on top.

But I always forget to note the similarities this has to the kick extend joseki.

I'm always dissatisfied with how easy my opponent settles under my 3 space high-low extension when I am very strong in the area.
Maybe this is the solution.

It's obvious how to attack when you can kick from the side of your high stone without hurting your low stone, but when it's your high stone that is already strong it seems trickier....

1-2-3 Seems like black is hurting himself too much
3-4-5 Seems great for black because both sides can fend for themselves, one side is even settled.
5-6-7 requires more information of the board.

edit:
A post which shows how I can expand how I think when dealing with thickness.

Also played a few games. Lost half Won half.
I feel stronger than the 4kyus but I feel so weak playing 1kyus.
Not really trying anything new, just focusing on creating weak groups for my opponent.

A game in which I think to treat a stone lightly but then cling to it madly and die horribly all over the board.



A game in which I am given massive thickness but try to hard to start a fight and die.



A game in which I enclose the center and my opponent must enter in the middle. I have trouble with cleanly killing a group and I have Life and Death comes down to a Ko and Semeai



I think I'm going to start playing more often. I want to start playing blitz games but I always get too nervous.

My few words of advice: Blitz games are no good. You will not learn anything. Simply you don't have enough time to think and analyse situation, and reading in such time constrained condition is just a mess. Instead of playing mindless blitz games it is better to go through some pro games. Less stress :), much more of a good stuff (opening, shapes, direction of play etc).
Go is not an arcade game, and should not be.

Nice diagrams on 3 space high-low extension.
Often see in my games.
Keep it up!

In the game against wangy how would deal with invasion on H3 if you didnot have support on M4?

Ack yeah, that's why I'm always running out of time. So much analyzing. But i figured being forced to think faster would speed that up and improve my regular games.

Hah interesting analogy. I suppose pro games would be an upgrade from sitting in the kgs lobby watching the 5d games :p
I haven't played through one of those in ages.

Uhh, it's kind of hard to say.



This is what I imagine would happen. And actually maybe even what I should have done in game. haha.
So thanks for asking and letting me see this as well!

This is why I'm trying to find different responses to mid game situations like this because with different stones on the board I feel like I deserve a better result.

One of those games you win but it sure doesn't feel like it.

Got lucky at the start but white grabbed every point he could. And I sure felt like I was pushed around.

So in my game with skydyr I became hugely accustomed to the vulgar diagonal cut.

He played it I think twice at the end and it led to me losing.

I guess I just didnt' consider it because it was "bad shape" but if it is, i don't even really know how to punish it haha.

Maybe from now on when my opponent is strong in the area I'll remember to consider it.
Also for myself when I have a lot of strength.

I just remember the second time i saw it thinking. You again. and anger. hahaha.

Well, lots of things work when you have lots of strength, but at the time I think I played that way because black was losing any other way and needed to make something big happen, since if it didn't work it didn't change the outcome, but it might if it did.

I'm back
Played a game.
Lost.
Saw the terror of an out of control moyo.
Opponent made 2, arguably 3, pass moves that let me catch up.
I handle invasions poorly.
I don't lose by as much as I thought I would.



I think 104 Was the losing move
After move 27 I thought I would lose by 100 points

Maybe instead of :W22: I should reduce K15

Maybe there was a better way to handle O12
or was it an overplay I just didn't know how to punish.

Also the Upper Right corner didn't help lol.
A lot of good joseki did me :oops:

Ah well, it's good to be back.

Something that didn't really make sense to me was approaching from farther away to discourage a pincer.

As far as I could tell there was less pressure on the corner stone so a pincer would be easier.

But I guess the fact that it's hard to connect the two stones when white changes direction is enough.



Some loose go thoughts.

W R7 discourages a pincer, yes, but W also gives B the choice of R5.
So globally, the R7 approach must be worth it to allow B R5,
otherwise what's wrong with the R6 approach.

That's what I don't know. The only time I know to play two spaces is in the kobyashi opening.

Supposedly the marked black stone works really well with the pincer stone?

But I guess this is different because the corner stone is lower.
So allowing R4 isn't as big a deal as allowing R5



Another thing I wonder is

In both cases I would prefer "a" to negate the influence along the side.
On the bottom of the board "b" would be too far because the group would certainly be too cramped.

But at the top "b" wouldn't be that cramped. Am I taking too little by preferring "a"?
Or is "b" just a different style that invites fighting.

I guess y'all are talking about #151, but the SGF file does not seem to exist anymore. :(

Probably this. Huge difference between 3-4 and 4-4:
for example, just look at the number of pages dedicated to each (in Takao or Ishida). :)

My feeling is :white: (b) and :black: (c).

But I also feel that at these levels, we would make
much bigger and much worse mistakes in the follow-ups,
so the focus is on those bigger mistakes, and less on (a),(b),(c), or (d).
(Not to say the opening is not important; it is good to study, of course;
but when we make most of our mistakes in the follow-ups,
they become more important and more urgent to fix.)

(I think :white: (a) is also perfectly playable and leads to
a different game, but I prefer :white: (b); yes, probably a matter of preference on the top.
I'm not sure of a good distance from W's wall on LL corner,
but B cannot approach too close to it.)

Ah strange that you can't see it, here you go. It was just a small few diagrams.



Interestingly Nick Sibicky just recorded a lecture where gu li plays against someone who pincers his two space approach to the 3-4.



And even though it was farther, white still manages to jump in and settle the corner pretty easily.

a different game, but I prefer :white: (b); yes, probably a matter of preference on the top.
I'm not sure of a good distance from W's wall on LL corner,
but B cannot approach too close to it.)


I suppose you're right that there are bigger mistakes outside the opening, but I prefer thinking about the opening. It's easier. Or maybe not easier, just more enjoyable.

So these are the follow ups for black.
I think (a) is normally a bad move because it's pre-pinched. But that might be different thanks to the support of the shimari.
I don't like (b) because white at O16 reaches naturally to K16. Though it might be considered too many moves on this side depending on the rest of the board.
I think (c) and (d) are sort of aimless invasions. Although (c) has the ko potential by attaching to O16
I think (e) would be possible later.
(g) is another move for later if you really want to approach from that side.
(h) might as well throw this one in for consideration too. Haha.
(f) is my favorite because it's hard to find a good answer as white.

(a) poor connection to the 4-4 stone. If black invades at 3-3 white's wall will look over concentrated or it will face the wrong way.
(b) seems very low. very slow.
(c) Better connection with the 4-4 stone but there's still the invasion point.
(d) Better connection but again still invasion points
(e) Personally I think the two stones are too far from the corner. But I could be wrong.

For these reasons I don't like K17 but it does lead me to like L17.
In this case if black approaches this close again O16 is well placed (Still with invasion points) But also black is more easily invaded.

For fun.

(d) might be good because the invasion isn't so serious without the checking stone.
(c) and (b) seem too weird to me. Are these normal moves?
(a) I think this looks weird for white. Now that white invested a move at a I think that makes it okay for black to invade at (b),(c),(d),(e) Though I expect this thought could very well be wrong.

Actually I think a lot of these thoughts might be wrong haha.

But I am especially curious about Fig 1.2 (e)
And the value of L17 instead of K17

My correspondence game with skydyr.
I really prefer correspondence games.
They're a lot more fun, and I get more time to think. Easier to play games when I don't have to play it all at once.
(Unusedname on OGS, challenge me!)



I think the most important mistakes are

:w26: I don't know how to make sure I don't make this mistake again. I feel like I won't recognize when I'm making this kind of mistake.
:w28: Need to be comfortable with more joseki. Need to play more games.
:w32: I thought I read something bad for white.
Maybe :w46: Uhhhh I'm not sure about this move. I thought it was a great move. But maybe My stones are too weak to play a move like this?
Maybe :w52: Idk I think this probe really helped strengthen black. Also maybe the only interesting move in the game. (I've started to worry I have a boring style. I think the moves I come up with are very plain and unimaginative)
Maybe :w62: I didn't really get a good attack off on the shimari.
:w90: Lazy reading. I read that I could cut through for a lot of points but didn't fully read the outcome. Same as :w32: Bad habit.

This game is actually what made me start posting all that stuff about the opening.
I felt like I did perfect for the first 24 moves
I felt way ahead.'

I counted myself down 10 when I resigned.

My thoughts:

With :b7: my idea was to devalue the right side since white had invested 2 stones to black's one. In retrospect, I suspect a simple small knight's move would have been fine.

:b19: I wonder if black should have tenukied and left this stone to fend for itself.

:w20: I'm not sure about. I think white could have played more severely, as with an inside shoulder hit.

At :w26: things are settled already, so it's a question of whether this or the upper left is bigger. I suspect the upper left is.

On the alternative for :w28: This really depends on the followup you envision. If black hanes, is white going to extend, block, crosscut, what? I don't think the extension is good for white, as there's no stone on the other side to really build a moyo from. I don't like the block also, because black strengthens a big side while white gets a medium sized corner. I thought the game move was fine, to take sente simply.

At :w46: I was a bit surprised you didn't aim at the eye stealing point. I remember feeling after this that my group was okay so I had a free rein to play elsewhere.

:w54: I hated this move, but didn't think I had the time to jump in from the bottom.

:b67: I felt better after this actually. Black had reduced white's framework decently, and then took profit though in gote. I don't think I noticed the cutting aji right away. Perhaps the bottom side was bigger, but I thought it would end up dameish. I definitely knew I was behind, though.

:w68: too close? wrong reducing move? I'm not sure. The ensuing invasion certainly helped black catch up.

I don't have a lot to say about the rest of the game that you didn't. I do feel, though, that my openings lately have been quite lacking, and that I make up for it in the middle and endgame.

I think :b7: was a fine splitting move.
:b19: I would never think of tenuki. But I guess there are still other big spots on the board. Could find sente approaching the top.

:w20: I don't know if I thought of this in game, but I'd be afraid to shoulder hit on the inside.
If white ends up with thickness facing the bottom it's in gote. And black gets the big move at the bottom.
If white separates the two black stones, white's corner enclosure is thin.
Though to be honest I don't know a comfortable sequence for white splitting the two black stones. All the variations I see are ugly and crude.

:w28: I was thinking extend, block. It would make the side nice for white.

:w46: I don't remember if I mentioned this in our review but I could never find time to poke the eye shape.

:w54: :ugeek: :pride:

:b67: interesting that we both feel positive about this exchange.

:w68: Ah, maybe. I didn't expect E4. Maybe F3 is fine. W: F3 B: E4 W: F4 threatening to surround again and then claiming the side.
