I thought that I'd make a thread in which kyu players share some of their brief moments of clarity in their otherwise clouded minds. What I'm looking for are moves or postions, whether they were shown to you by a teacher or discovered on your own, that exemplify a mistake that you have habitually been making, that you have recognized as bad, and have resolved to avoid in the future.

I'll get the ball rolling with this position:

[go]$$Bc Black has just exchanged :b1: for :w2: . \n What is his next move?
$$ --------------------
$$ | . . . . . . O . . . .
$$ | X O O . O O X O . . .
$$ | . X O O X X X O . 2 .
$$ | . X X X O . . X O . .
$$ | . . . . O . X . . . .
$$ | . . . O . . 1 . . . .
$$ | . . X . . . . . . . .
$$ | . . . . . . . . . . .
$$ | . . . . . . . . . . .[/go]


This problem has been lifted from an answer page of Making Good Shape. Exchanging :b1: for :w2: was the hard part. Only the easy part remains. What is black's move?

In a recent ASR game, during a review generously offered by a stronger observer, my opponent remarked that both he and I appeared to have the tendency to play close to our own stones. This is one such situation, and one that I hope to recognize and avoid in the future.

I'f you're like me, it's kind of hard to see if black can live if he tenukis (he can, as shown below), but it's clear that it's better for him not to get shut in:

[go]$$Wc :w3: captured at the clouded point. \n B is shut in, White has captured \n the marked stone in a ladder.
$$ --------------------
$$ | . . . . . . O . . . .
$$ | X O O . O O X O . . .
$$ | 8 X O O X X X O . O .
$$ | . X X X O . . X O . .
$$ | 4 ? 6 . O . X . . . .
$$ | . 2 1 O . . X . . . .
$$ | . 5 Y . . . . . . . .
$$ | . . 7 . . . . . . . .
$$ | . . . . . . . . . . .[/go]



So you whack down a stone here:

[go]$$Bc Not good enough
$$ --------------------
$$ | . . . . . . O . . .
$$ | X O O . O O X O . . .
$$ | . X O O X X X O . O .
$$ | . X X X O . . X O . .
$$ | . . . . O . X . . . .
$$ | . . 1 O . . X . . . .
$$ | . . X . . . . . . . .
$$ | . . . . . . . . . . .
$$ | . . . . . . . . . . .[/go]


Here is the correct answer:

[go]$$Bc Yowza.
$$ --------------------
$$ | . . . . . . O . . .
$$ | X O O . O O X O . . .
$$ | . X O O X X X O . O .
$$ | . X X X O . . X O . .
$$ | . . . . O . X . . . .
$$ | . . a O . . X . . . .
$$ | . . X . . . . . . . .
$$ | . . 1 . . . . . . . .
$$ | . . . . . . . . . . .[/go]


:b1: is the correct move, and it becomes painfully obvious once you see it on the board that it's better than a. Black has gotten farther out, he has prevented white from cutting at a, and white's stones are in deeper trouble.

Lesson learned: By protecting a weakness with a move farther away, you can multiply your advantages. *sinks back into his befuddled fog*

Great thread! I wouldn't have played the right move in your position ^^ Most likely I would have just hopped to G12...

Coincidentally I had such an insight just a couple of minutes ago while reading Volume 2 of Dictionary of Basic Tesuji.

[go]$$Wc White to escape while spoiling Black's shape

The task is to escape with your stones. But not just somehow, of course you must do it the most efficient way : )

Hint:
M19 is wrong =P


Starting point:

$$ . . . . . . . . . . . . |
$$ . . , . . . . . , . . . |

White would just love to play :w1: .

If Black answers at :b2:, he will be forced to connect at the marked stone after :w3: and White would have escaped beautifully while making a dumbling out of Black's stones.

Of course Black can quite easily resist this line.

$$ . . , . . . . . , . . . |
$$ . . . . . . . . . . . . |[/go]


Black just extending to the first line and cutting the White stones is the truth.
White's only chance is to connect at :w3: but after Black cuts at :b4: he will either capture one stone at 'a' or capture three in a ladder at 'b' - and that is the truth.


Solution:
I can't go home again unless I find a stone a rose a door and that is the truth.

The stone being the stone, the rose the Tesuji to open an exit door.

:w3: is the Tesuji which opens a door to a wonderful insight. That is: If you see there might be ladder, try to break it with a forcing move BEFOREHAND! (Zwischenzug! Broaden your view for a position!)
'a' and 'b' are Miai now, so the best Black can do is playing :b4:. White just gained a favourable exchange when he conlcudes with 'a'.


Sorry for Randalling.

daal,
What if the ladder is bad for W? Then the W push at (a) won't work.
Depending on the rest of the board, B may want to kill or attack W with (b).
Also, B(c) or (d) may be big (again, depending on the rest of the board)?

You raise some valid points Ed, thanks for your input. Regarding the ladder, that's true, and in that case indeed b,c and d could all be interesting. For me however the main thrust is the realization (assuming that the ladder works) that there is a better move than a.

This "insight" is more of a general blah-blah than a nice specific position, but I'm going to post it anyway, because this single thought appears to have turned my game around, and instilled it with confidence and bite.

The thought, which came from Robert Jasiek's book on Joseki strategy is simply this:

In his book Joseki Strategy, Robert Jasiek wrote:
...big moves are not as big as their visual appearance tempts one to believe because it requires several moves to turn a sphere of influence entirely into territory. Contrarily, an urgent move realises its aims much faster. Therefore the territorial value on average per played stone tends to be greater for urgent moves than for big moves.


This, along with Robert's perhaps long-winded but nonetheless practical definitions of his concepts "stability" and "investment," have given me a handle that seems to be attached to a pointed stick. I think it's left a number of my opponents wondering what had hit them. (I know, because I've felt it often enough myself).

I must admit, I find this change a bit suspect, but apparently I'm correcting a fundamental error: overestimating the value of big points. So now, instead of spending my middle-game struggling to prevent my opponents from decimating my thin positions, I've been picking fights myself that I'm more likely to win. I'm starting to think that my perception of myself as a lousy fighter may have arisen from the fact that I had been fighting the wrong fights.
