Consider the two alternatives below. To my eye the first is preferable to the second. White's stones are all on the third or fourth line with no defects.

Agree about no defects, but there is endgame implication in the 'a' area, no?

In the other variation, white seems to have better endgame follow up.

Anyway, compared to the Atari I missed in the review from that last position you gave, this is subtle, it seems :-)

I guess the wall with defects has endgame issues on the other side, too.

I was feeling a little down, so I didn't study that much this weekend. However, I did make it to the Seattle Go Center last week for a casual game. I never played him before, but I guess he said he is Tygem 5d - that's a bit stronger than me, so I took black.

I don't remember the precise game, and the sequence is messed up near the end. However, I remember up until the middle game. The end result was a loss by me by 4 points on the board. So he played better than me, and seems a bit stronger than me at the moment.

Here's the game record, as I roughly recollect it, with a few comments.

The marked move is not thinking globally. I can cut through him, but white's aim is to counter-attack. It makes more sense to attack the group as a whole:

I like my opponent's idea of probing the 3-3 prior to the move above, to retain aji:

The downside is that I get gote, but it's nice to have the aji there in the lower left.

This move aims to expand the right side, but I think it's too ambitious - the right side is still open. And the bottom black kgroup is still weak.

Therefore, I think it's in the wrong direction. This way might be better:

I can more naturally get territory this way.

The three white stones are small. It makes more sense to connect my stones and form one powerful group:

My intention was to settle the top group in sente, but as a result, I ended up with a weak-ish group with weird shape. I think it's better to have a normal shape, aiming at white's thinness for later:

Learning Points:
1. Think more globally - what stones are important? What stones can be given up? Should I attack on a larger scale?
2. Avoid playing bad plays, making bad shape, just to get sente. Take gote with a good shape, if necessary.
3. Use probes for aji.
4. Consider the direction more carefully. I think I make mistake in direction often. Think more carefully before driving my opponent's weak group in a given direction.

Kirby's Youtube Debut

Since Youtube streaming is all the rage these days, I decided to extend this journal to include recordings of live streams of my games. So from here forward, I'll try to include a live stream recording of my game as I played it, along with the normal review and analysis.

Please feel free to watch the video, though, I'm not that much of an entertainer - maybe I need to buy a joke book or something. One benefit of these recordings for myself will be that I can later look at the recording and try to see where I had a hard time during the game. Maybe if I'm struggling in a particular type of situation often over time, it will be a good indicator of what I need to improve.

Anyway, here is today's game:

I played against KGS 5d, but he gave me 6 stones - and still won :-(

I think this game again illustrated my lack of reading prowess. I misread a critical section of the game and lost a large group of stones. I need to improve this.

For those interested, here is the video recording:

Going forward, I plan to continue streaming games on YouTube. Feedback is welcome on games, as usual, but feedback on my presentation would also be appreciated (e.g. tell more jokes, talk in a more lively way, etc.). :-)

I think the marked move is nice for reducing black's central potential, but it gives no real pressure to white.

It's probably more efficient to pressure his stones:

I actually "know" this shape, though, I guess that this proves that I don't know it.

I thought that this move was better, since white just gets only points on the side. In retrospect, maybe just playing solidly is better:

I don't really feel strongly about this, though. The game wasn't that bad in this part.

The game is probably still good for me then.

Learning Points
1. Reading. I really haven't invested enough time into problems.
2. Evaluation of what's bigger. A couple of times in this game (Position 4 and Position 6), I should have taken more time to compare what was a better choice between two options. I might have opted for the wrong choice in these positions.

So I guess it's clear that I need to do more go problems. And I should be able to read faster, too. I hope I get more ambition to do this.

Kirby · **#830**

Since streaming was kind of fun, just for kicks, I made another video and chat about a semi-random news article on cyberoro.

Not a lot of study content, but mostly just chatting about the article.

I'll probably stream another one of my own games again today - maybe in a few hours from now.

However, in order for any of this to mean something Black has to answer White 1 below with Black 2 to prevent a second eye. Both 'a' and 'b' threaten to connect. Can White kill Black in the corner or can Black make use of the aji to survive?

Interesting point, ez4u. I'll admit that I didn't read it out much. It looked a bit scary, and I added a move.

Since the move below is sente, the most interesting move is if white takes an eye:

For example, hane or an inside move can be answered by simply making an eye:

Now white can't do much, since black 'b' is sente.

Therefore, the most interesting thing is if white takes the eye:

In order to save his stones, it would seem that black has to disconnect, but...:

Now 'a' and 'b' pose a problem for black as above.

Black can try to push white to avoid the eye:

I think this might be the way for black. I haven't seen a refutation, anyway.

ez4u · **#833**

Careful, the N2 stone in black.

ez4u · **#834**

As a result, Black can answer the R2 attachment by descending to Q1 I think.

Kirby · **#835**

I see, you can connect that way.

BTW, S1 doesn't work after R2?

S1 is met by either R2 or S2 I think. The threats to connect always seem to give Black that crucial extra tempo.

Kirby · **#837**

R2 is already played, no?

Kirby · **#838**

I think you misunderstand what I asked, but I also think I made a mistake.

In response to your original question, I had a typo in the diagram (white stone instead of black), but my basic "solution" was this:

Going back to the reading mistake in the upper right corner of the latest game, it looked like you played the descent at S18 without considering alternatives. This move is good shape but too slow (given the W tesuji). Simply taking a W liberty wins the capturing race. So the earlier cut at S16 was actually good.

Kirby · **#840**

Haha, yes. You are right.
