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 · Post by **Kirby** » Wed Dec 03, 2014 1:01 pm

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.

Position 1

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.

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.

I played a game against KGS 1k today. I think he might be a bit weaker than that, based on the game.

Anyway, here's a short review. I stopped reviewing after I lived in the middle. It seemed like the game was won then. That being said, I could have had a potential crisis, since I played sloppily after gaining a bit of a lead.

The following positions stuck out as ones where I should have given more thought.

Position 1

Above, I think the clamp is kind of bogus. I should just cut, and it should be fine:

As white is strong on the top, and has a presence on the left, I can't imagine black getting a great result (see SGF variation).

White can live in the corner, so it seems an easy fight for white.

Position 2

In the game, black could have made a strong position with this:

So in retrospect, it's probably simpler to just answer his approach simply, then invade in a standard way for Chinese opening:

I think it's much easier for white than with the black wall.

With the marked white move above, I started getting really heavy. I should stop overplaying, and let black get territory on the right side - he has many stones there.

Just jumping lightly should be enough:

After getting heavy, it was a bit of a crisis - I had to find a way to live. He played lightly and let me live without problems. The crisis could have been avoided, however, if I simply play lightly. I should have done that.

IMO above jump is also heavy.
my choice is as below.
when winning..you should not take ANY risk and cover your weakness.

Welcome back, Kirby!

I know I'm a few days late, but I actually have only just started really looking around on the forum again for the first time since July.

I think it's good positional judgement. This way, I feel white is a good 30 points ahead, with no weak groups.

By the way, it's good to hear from you, again!
