Life In 19x19

Hi there.

Im working through All about L&D again. I try to look at some deviations of the explained main lines and wanted to have a place where i can put some doubtful insights, so others can have my doubts too.

Im beginning with a standard fail attack on the haned L+1 Group with leg on the short side.

$$ | 3 a X O . . .
$$ | 4 X X O . . .
$$ | . O O O . . .
$$ | . . . . . . .[/go]

Now black can choose between a and b, the book suggests (a), but (b) looked more natural to me, so I wanted to prove it inferior.

And now at c fights the ko: An one approach move ko
If White plays at 3 first :

The other variant with b in the first diagram:

[go]$$W elsewhere fights the ko

$$ | . O X X O O .
$$ | O . X O . . .
$$ | X X X O . . .
$$ | 1 O O O . . .
$$ | . . . . . . .[/go]

In both cases we have an approach move ko and the only difference is the sacrifice point at .

I suspect this is the problem with "b":

Yay, I somehow missed that one. Thx

One of my late night games ended in an interesting fight.
I sure did some serious bad thing to let me split that easily. I tried to get my way out somehow and tried every turn.
At move 93 my opponent somehow stumbled. I tried to find the right answer afterwards, but only with mediocre results.

That's a funny game - what a dumpling black got!

30 and 32 seem a bit sheepish. There's no sense in giving atari at B13 if you don't plan to play the ko, right? After 32, you've taken gote twice, but you've gotten a worse result than if you had, for example, played B13 at B12.

A game again. The Tides were turning often as we both blundered much. The end was still close.

Today one game from the category "Get strong at losing graceful". See yourself.


Finally lost at move 185 after the tide turning 2 times .

Also played my first kgs after some years.

Im doing the graded Go problems 3 at the moment, cause i only want to bruise through problems right now and am too lazy to think hard. Still funny what mistakes i can make with these ddk problems. Today I had to stop and think at one problem for fifteen minutes to get it wrong after all.

I thought the first to be better cause no outside assumptions are needed one space down left. I looked at the solution and mine wasn't there. (deviation at at soution 1). If you like, refute.
My tries are somewhat doubtful, like always at these damn corners.

I hate it losin drunk to guys 5 stones worse than me ten times in a row.

I thihk this game was intersting as there was a big trade and a messy fight, but it was just a 10 min blitz so no deep thoughts in it.



P.S.: had to correct the most embarrasing typose ^^

I really had problems against the 8 kyus on wbaduk, but now i beat up the 6 kyu's like i did with the nerds in school. must be a mood thing. Today winnig is fashion, Maybe tomorrow is a losin day.

I don't think your solution works, since White could play as:

Yes. Thanks. I somehow was too blind for the b.
