It's interesting. I think I considered it a little, maybe not during the game but at least when I reviewed it afterwards, but thought that Q14 would make it fail... It appears it doesn't.

For q15, I read the following :

b-r13, w-q15, b-q14, w-r15, b-p16, w-p14, b-q13. Then, if white hane at q18, b p18, r18, then o18 and black is safe...

Though r18 may not be the strongest resistance.

So, after white hane at q18 and b answer at p18, white cut at p17, black give atari at r18, then white can squeeze by adding a stone to the sacrifice (w q19, b p19, w o16, black capture with r19, w q18, b q19, w o15, b q18).

Then, white can start from the corner or from the other side... If w s18, then b-s19, w-t17 is a ko that black take first. Or white can descend at t18 instead. B must throw in to be able to connect (oiotoshi), so W corner live, and then he can enclose B heavy, eyeless dumpling...

So Black has to allow white to connect underneath with o17, which is a major loss.

I currently am cursed with a bad internet connection, so the only games (well, game) I play at the moment are correspondence games.

I recently finished Grade Go Problems for beginners 3 (the L&D problems were maybe a little too easy, but I think I should go back to the endgame ones at some point. Unfortunately, there's not a lot of those)

So I will go through the 1001 L&D problems. Went through the 56 first today (but I already did those some time ago).

Other than that, I'm currently going through the games of the Sanjubango between Shusaku and Ota Yuzo (at the moment I'm at the sixth). I play at least each games two times, the first without reading the comment. If I feel the game is interesting or particularly well played, then I might dedicate more time to it and maybe even try to memorize the first hundred or so moves.

I finally got back a good internet connection, so I played a game today. I feel like I won more because of my opponent mistakes than my own good (?) play, but at the same time he didn't make outrageous blunder like playing an obviously broken ladder (did I already mention that one game? I really felt embarrassed for my opponent then, and hope it was because he was very tired/drunk)

Apart from that, I continued at my seven pages/day on 1001 L&D problems (that is, the minimum number of page to be over 50 problems. Because leaving a page half finished just bother me), so I finished the 272 first problems at the moment.

I also finally got Kageyama's Lessons in the Fundamentals of Go and it's a very good read. It's really hard to follow his instruction to only read one chapter per day.

It is disappointing that Black later gets to take this stone, in sente. At S17 has to be considered.

This would be the wrong atari. At P14 and play the driving style.

is just unnecessary.

At J17 looks better. Black has played a few dubious moves, but still comes away with a playable result.

looks thin to me, but

pushes it into shape?

This time White gets sente.

should clearly play the small nadare.

seems OK. But I disagree with

: you are going to regret not playing at D6.

I would play D17 immediately. The two stones are light.

would look much better at B15, I'd say.

White won in the subsequent fighting, but it's not specially instructive.

You're right. I was not consistent in what I wanted in this corner.

said "I want to take the corner", but then

was "I changed my mind, the side is more interesting. S17 is, in my mind, sente because of the follow up at S15 which take away B base, and then I can play P15.

looks thin to me, but pushes it into shape?

In the game, I read L16 (doesn't seems to work), and then L15 followed by the connection at J16. Because the way I envisaged to cut didn't work, I thought I couldn't do so and played

. But w-L15, b-K15, w-k16, b-k14 then w-L16 cut black. Also, I was too worried by the cut at O14.

This time White gets sente. should clearly play the small nadare. seems OK. But I disagree with : you are going to regret not playing at D6.

I agree that

was bad, but I don't like d6 because of black e6 afterwards. White at E6 looks better to me.

1001 L&D : Finished the 332 first problems... Hum, I actually did one more page than usual...

Daily game :

I won this because my opponent let me hane at the end of his two stones

. Funnily I had just read "The struggle to get ahead" in Lessons in the Fundamentals beforehand.

Hi Bki,

maybe your var (J15) is better.
Another possibility is peep N16, followed by N17.

maybe still N16, N17;
or, just jump directly L13.

not sure about this direction.

W gives you a chance to link up (N14, etc.)
in exchange for small life in the corner. Hmmm...

result of this sequence seems good for W.
Maybe just jump K9.

jump L3.

110 H7 kosumi.

115 Bad exchange; bad sente. You killed your R3 aji.

120 Strange. Follow through with E4.

124 maybe E14 bigger.

132 yes, D10 get ahead is better.

Hi EdLee.

My first instincts on peeps is "don't". I read so much about how much player have the bad habit of strengthening the opponent by peeping that I ended up having the opposite problem.

But here, I don't have many chance to cut because I'm two spaces away from that group. It doesn't strengthen him that much because it also limit his eyespace. And then I can turn back and attack two groups at once without worry about mine while making territory on the right side.

I need to consider the peep more often.

Basically at these levels,
we easily get confused.
Example: when a peep is bad, we play it.
When a peep is good, we miss it.

The same for other forcing moves (e.g.

115 ).

You are correct about your situation with peeps:
your instinct is wrong about avoiding peeps.
Instead, assess each case individually.
Get rid of your mental block about peeps,
and other aspects of Go.
(Touched on in a previous discussion: posts 12, 13.)

Could you elaborate on the R3 aji?

here seems to be the only move. If

hane at R1, then S1, Q1, T2 and connecting with R6 and living in the corner are miai, but if

descend as in the diagram, then what? S1 is no longer sente, so black can no longer live and

is forced, but after

, black lose the capturing race.

L&D : At the 388th problem. If I have the courage, I might finish the one move problem later.

Game : Had a fun fighting game today. There's not enough people playing the takamoku. I made some mistakes, but my opponent didn't know how to handle them, so it's his own fault. Why choose a variation if you don't know it well enough (or is confident in your reading) to get a superior result if your opponent deviate?

How about going back one move? Your slide to P2 was interesting, daring W to block at O2. I presume you had some plan to handle that, using the corner aji. But when W blocked at P3, you chickened out and connected at O2. Why not go all in, extending to Q2 or even R3? If you play Q2 and W blocks at O2, you have moves like R3 or S3 or R4 to try to live in the corner. It looks to me like there is enough aji to at least get a ko for life. Since B is far behind, this seems like a golden opportunity.

If cutting doesn't work, what about trying to live. The "my opponent's good move is my good move" idea.

It looks like an L group which is dead, but you can threaten to connect to increase your eyespace in sente.

L&D : At the 450th problem of 1001 L&D problems. So far the 3 moves problems aren't really more difficult.

I won a lost game today. At the start of the endgame, I counted and found myself losing, but didn't count well enough and though that this could still be won, so I didn't resign. Then my opponent missed that I had set up a semedori, and then when I punished him he let me capture 4 stone and save 3 of mine, instead of only letting me capturing two.

Without that double blunder, I would have lost.

I also missed a golden opportunity to cut off a big part of his group and kill it earlier in the middle game, which would have allowed me to win the game comfortably. The last player to blunder win the game, heh?

(And earlier, I also let him living in the corner when he should have died had I not given him the opportunity to connect in sente).

L&D : Not in the mind today, but I still did up to the 500th. Still, I didn't put as much effort as usual, and it showed in the number of mistake I made.

Game : I would like to feel proud of my wins for once. I mean, I make the dubious strategical decision to stake the game on whether or not I can kill a large group in the centre, but then surround it in a way that leave too much weaknesses, and come a point where my options are limited, I play the only move that leave me with some sort of chance, only to read out during my opponent time that actually, no, it doesn't work. And then he answer wrongly leading to his death. It's difficult to be happy about winning in such situations. I would prefer to have my mistake ruthlessly punished that way I would be more careful in subsequent games.
