I played the marked move. It doesn't make a lot of sense. Even if he responds, what to I gain? I should either tenuki, expecting to save the cut, or simply extend.

In response to black's threat on my corner, I connected the group. I can understand a possible tenuki if I was confident I could live, but was my move really that valuable? The fact that he captured the two white stones in sente was huge.

I should simply answer:

The marked invasion/probe is questionable. I could simply P5:

I regret the marked move and the sequence that followed more than anything else this game (suitable for #4, eh?). I did try to read a way for white to get profit here. I wanted it to work.

But I couldn't read something working. It felt like something was there, and it should work. So I still played the move.

This is a problem I must overcome.

---

Learning points.
1. If I do not read a sequence that works... Do not play it.
2. When playing tenuki, consider carefully if the tenuki is worth more than answering. I think ignoring his threat to my corner was very big, even if I ended up living.

Shaddy wrote:At move 60, L14 should eat the cutting stones.

I think you are correct. I didn't even consider it during the game.

Shaddy wrote:At move 74, G14 cut is more important than anything, IMO.

Hmm, I didn't realize how big it was. I suppose it makes both of his groups weak. Good idea.

I played three games today - well, the first was an escaper after the first 10 moves or so. The second one, I misread early on, then lost big pretty early.

Then I played the game I'm showing today.

I think I'm in a slump. I keep losing

Anyway, despite that, here is the review.

I thought I should keep pressure on the marked stones. But given that white is somewhat strong on the left, it's probably a safer strategy to just defend the corner - though it feels slightly slack.

Otherwise, it's too easy on white - and white made big corner profit later.

Learning points:
1. Read out capturing race clearly - don't just go by feeling.
2. Think carefully about when to play safely, and when to apply pressure. Too much pressure at wrong time makes me snap. Not enough pressure makes it easy for the opponent to attack.
3. Get out of this slump.

Hmm. I can understand the reason I played some of the moves at the time. For example, I had a reason for playing , to help in a particular variation, so I can understand my intention in playing it. But I agree that it looked silly later.

I wonder how to solve this.

Black 196 should be your original idea of atari. If White connects, you pull out your two stones. White is suffering from a lack of liberties and collapses. So you get to capture two stones and connect your groups. Can White live with only one move at 197? If not, capturing the two stones will even be sente for you.

Hmm, yes. Looks obvious now

I didn't consider the possibility that I could connect in sente. If I saved that group in sente, and then could play good endgame, maybe I would have had a chance.

My comment would be that go is not just a "dynamic" game. Sometimes, as at in the game, you have to think about occupying key points. They may appear not to have so much effect on your opponent, but that is a kind of illusion.

Recently you seem quite concentrated on the idea that you can read everything out and/or have reasons for every play. This is giving your Go a very self-centered look. You seem to be ignoring alternatives for your opponent and various general conditions/weaknesses on the board that can not yet be resolved into specific tactical situations. In other words, I think your Go is out of balance at the moment. Hence your slump.

In response to black's threat on my corner, I connected the group. I can understand a possible tenuki if I was confident I could live, but was my move really that valuable? The fact that he captured the two white stones in sente was huge.

The real reason to defend the corner is not that Black gains a lot of points by capturing the two stones. It is that there is a cut shown below with the double hane of 'a', 'c'. Even if Black defends that cut, there is still the possibility that invading later into the gap between the two-stone pillar at Q11 and the shimari in the lower right corner will threaten Black's eyes. This is especially important because, as Shaddy pointed out, White can cut on the left with a play at 'd'. (Note that the marked Black stone was a big mistake and should have been played at 'e' to make the cut more difficult and less threatening.) As mentioned in my previous post, currently you do not seem to even be looking at these aspects of the game and your play is out of balance at the moment.

Otherwise, it's too easy on white - and white made big corner profit later.

...

You play 1 below and White starts the ko with 2. You know that White is going to play 'a' as the first ko threat, so you need at least two threats. What are they?

Thanks, Dave. To be clear about the balance comment, as applied to this situation, are you saying that I am not considering non-tactical implications?

For example, here, the cut that I could have in the future to potentially eliminate eyes?

Perhaps I should play, keeping in mind that not everything can be read out in the immediate situation, aiming for future possibilities?

Edit: How is the current view self-centered? I'm not sure I follow 100%.

I played a game against KGS 1d today. Finally, I broke my losing streak. I don't think I've fixed the "balance" in my game, as ez4u pointed at - I don't quite understand all of the nuances. But anyway, this game doesn't really feel like a won game, because I made it very risky.


My review is shown below. I have to go to a meeting shortly, so I do not have time to post diagrams, yet. I will aim to do that a bit later today.

Both of the moves above seem slow. After , maybe I could tenuki.

I had a plan behind the white move above, but it was a single-variation plan. In other words, I had tunnel vision.

I think it's simpler to just extend on the left. Seems bigger.

The marked white move above seems really slow. Given the marked black move, it's hard to consider pressuring black much.
And it's also hard to see white getting attacked that much if I move out into the center.

Still, I think I should play something toward the center.

I think the marked white stone is an overplay, given that I need to consider the life of my large group in the center.

Probably, I should just reduce from the other side:

I was lucky this game that I didn't die. It got to be a crisis after I made two weak groups. This happened because I was too excited to move into the center, and got cut off (Position 5).

Learning points:
1. Consider the safety of my own groups.
2. Don't play a move just because it works well in one particular variation that I read. Play because it will work well even when my opponent resists.
3. Try harder to play the biggest move in the opening.
