In the game I played the marked move. I didn't expect to capture the stone, but I wanted influence to aid in the development of the bottom right. This stone ended up being one that was captured, so I'm not sure it makes sense to have been played. If I wanted influence and that's all I wanted, maybe a more direct approach is better:

I don't know how white will respond, but the way above gives a move more at the purpose of what I'm trying to achieve, and will likely allow me to get sente to play a big point like the one on the right.

I should have read so that I was 100% sure I could kill white, or I should have found a way to get sente. Black was strong in the bottom right, and to let white live in sente is like a slap in the face.

Some general ideas that I can learn from based on these last positions:

1.) Play a move that accomplishes the purpose I want to accomplish cleanly. Don't play something vague that doesn't do exactly what I want it to do.
2.) Use good direction in fighting.
3.) Work harder to get sente when I should get it.

What about move 17 Black H3 instead of H7?

Black 51 I would play R9 or R10 to steal his eye space instead. Let him run to the center towards your stones. They aren't all that thick but probably you will have a chance to fix J7 and have it also serve as an attacking move.

Similar for Black 59 I would reduce eye space at S5.

Shaddy · **#204**

C14 IS MASSIVE. I don't know if I'd tenuki a 4-4 approach to get it, but I definitely would have played it after that sequence.

Great idea. I don't know why, but I don't recall even considering this move in the game. Maybe it was the pressure of being in a tournament? I think H3 is a better idea than H7.

Sounds like a good idea, but do you think black will get enough compensation? I guess in the game I didn't kill him anyway since he had eyespace, so I didn't get as much compensation as I wanted, but maybe I could get center influence.

How do you decide between trying to seal in from above and pushing eyespace below? Because black already has some stones on the outside?

This I can see more clearly. It's probably better than in the game. I could probably get sente to play around Q18, for example.

I guess this is evidence that I still don't understand this sequence that well (though, I don't know of a better way to respond to this type of pincer that well, either). I guess C14 has the benefit of protecting the cut, and it's also good territorially.

It's hard for me to assess how big this is.

Following previous practice of taking a look at a pro game and guessing the moves, here's a game record with my comments between Cho Hunhyun and Park Jungsang.

I guess Park Jungsang looks like this:

I didn't consider the marked move, but I think it's good. I considered this:

The thing is, both of these help white to fix his three space extension nicely, making it stronger:

For this reason alone, I like his choice better.

Because I don't like black's shape when white hane's under. But this is gote, leaves the cut for white to exploit, and further, white doesn't want to necessarily hane, since it hurts his stones:

Black opted to move out his stones, whereas my instinct was to grab corner territory:

My idea is bad, because those stones are important - have to keep two white groups weak!

Now it's time to take territory, but my idea was to play here:

This is reckless, because white can get into the bottom, and also it's hard for black to attack severely with his semi-weak group floating in the center right.

Overall Thoughts

My thoughts differed from pro in several regards, but if I summarize, I think I misevaluated how to deal with the relative strengths of groups several times:
* I was concerned about corner shape when white would not exploit it anyway since it'd hurt his weak group.
* I thought about moves to move out of top right corner, which helped white strengthen his weak group.
* I thought about making territory when black needed to keep white's groups weak.
* I tried to attack when I have kind of weak group.

I think lesson from this game is to pay attention to what groups are weak and what groups are strong, and what implications that has on game. This sounds obvious, but clearly I do not understand it.

@magic sword comments:

1. The corner is gigantic and thick. It's nice to have that big territory, and the only potential left in that area is a (not particularly good) peep.

2. If you don't protect the cut, there will be a ladder. Modern pros sometimes disregard honte, but they almost never leave ladders on the board.

I can see your point on both comments. It's not helpful in knowing exactly *how* big this is, but I guess the point is, it's very big, and like you said, maybe I should come back and play it after the sequence in the top right.

Because I don't like black's shape when white hane's under. But this is gote, leaves the cut for white to exploit, and further, white doesn't want to necessarily hane, since it hurts his stones:

above shape, white will love to hanne if he can get it in sente.
problem of above sequence is that black will not play 5.
for example..
black can simply play as below.
white do not have time to capture :b3:

and lose momentum.

I agree that tenuki might be good idea. I also agree it's big territory when white does hane.

As white, I still don't like hurting marked stone above - it feels inefficient. For example, later in the game, if it was like this:

marked white stones have a harder time.

Kirby · **#213**

I'll be continuing this study journal, and will continue to post games I play, along with my thoughts and review.

Currently, I am KGS 1d. I made it to 2d briefly, but then went down again. In today's game, I played against KGS 4d with 3 stone handicap.

Here is the game, with my review.

Following are some decisions that I think were rather poor on my part.

In the game, I played 'a' with the intention to pressure the marked white stones.

I think it would have been simpler to just play 'b'. It gives me more territory, and his influence is not great.

White gets sente, but I think the result is ok.

In the game, I played 'a' to put more pressure on the white group. I think playing 'b' is slower, but solid, and can help in future battles.

Playing 'a' is okay, perhaps, but I shortly gave up on giving pressure a couple of moves later:

I think the marked move is big, but it is not consistent with continuing to pressure the white stones. It makes my previous knight's jump a little less meaningful.

The marked move, above, must be slack. It's black's area, so even if he tries to complicate things, I should at least hane.

Above is wrong, too, I feel. I cannot make many points on the bottom anyway, so it's best to get sente with this:

White just played the marked white move, and I tenuki with the marked black move, above. Just answering must be bigger:

There are at least 7 big mistakes that I feel here - at least from my post-game perspective. But despite this, I think I still had a good shot at winning the game... Kind of close, but I think black has a bit more.

That is, if I don't tenuki here :-)

Some takeaways from this game
* Check status of group before tenuki
* It is difficult to put a lot of pressure on a strong group. It may be better to play solidly in these cases.
* Avoid aji keshi.
* Before discarding a simple/natural variation, ensure that the alternative choice is really better.

I think the marked move is big, but it is not consistent with continuing to pressure the white stones. It makes my previous knight's jump a little less meaningful.

...

I think we need more than one plan and the ability to switch when the time is right. There is not so much pressure that Black can put on White. In the game, Black allowed White to cut off the center stones with 57. After that White gained more from pressuring Black than vice versa. Black should just give up the three stones and laugh at White's small-scale mindset!

@Position 2: I think it's a good exchange
@Position 3: B doesn't have a continued attack on W, this is a good move.

Your sacrificing idea seems simple, but brilliant. The idea never came to me at all. I have a very hard time sacrificing stones. Perhaps I have a small-scale mindset :-)

I would have probably just answered at c3 (or tenuki). Clamp and crawling on the 2nd line is not so spectacular. If white ignores then peep rather than clamp is probably the attacking move.

Something certainly felt wrong about moving on the second line while he was getting a wall. I was afraid of his approach, but maybe crawling made it worse.

Maybe the problem was earlier, even, since he could hane and get some influence in sente from the result of the top left (which I thought was ok for me at the time).

This hurt the marked stone and gave up too much on the right side.

It would have been better like this:

Since I keep corner and can get sente to play top, this is better. I learned this from my friend on KGS.

I should probably just do 3-3 invasion instead of marked move, because I am lacking in points.

The marked move is wrong, as explained in the SGF.

These are the major things I've learned this game:
* Be careful about selecting a move, based on my count of the points. If I am behind, get more points (eg. playing 3-3 in game, instead of on left as in Position 7).

* Don't play slow first-line move when it's important to be playing bigger area.

* Be careful of direction in joseki. Even if one particular line gave me corner territory in top right, it's obviously better to play inside if I want to keep the inside.
