Life In 19x19

Posted: **Thu Jun 04, 2015 1:21 am**

A couple of top of the head comments on the game vs. oggy.

Why not the pincer cum approach of R-13?

Why the footsweep? If you don't want to reply at F-16 or F-17, surely a pincer is indicated, to work with the White stones in the bottom left.

Too close, I think. How about C-11 or D-12?

Very bad. Surely G-14.

@Shaddy

Thanks for the review. I noticed you left a few tsumego problems:

At least this move works, I think:

Since black cannot play at 'a', white can live.

So the only other option might be to push, but then it's already a living shape.

Maybe I'm missing something since it's my own game, but those options seem to work.

For the second question...

I think the status is that white is dead.

After

So I was very stupid to ignore this in the game.

Regarding a few of your other comments:
"C16 puts more liberty pressure on Black. Either way, White's got a very promising game."
> Good point.

"Come on!"
> To be honest, I didn't even consider the variation you showed. But I like your point that putting stones next to opponent's stones doesn't constitute pressure. "I have to put them in the direction he's trying to go in." I felt like I was "pressuring" and attacking two groups, but it looks like I was just letting his group get stronger since I played in the wrong direction.

"J18 would be better here. This is the kind of move you cannot play unless you have checked that it works."
> Yes, I have a tendency to accept too much risk without reading out the result. It's a big problem.

Actually, it's not 100% clear to me after this position in the second problem:

Interesting. I feel that white isn't doing great locally in the bottom right, but I suppose that it's okay, considering the whole board - and it prevented black from doing something fancy on the bottom (or enclosing).

@Bill:
I need some time to process your other comments. I have to do a bit of work for my day job at the moment.

I thought about this more during my lunch break.

I'm starting to think it can result in ko in multiple ways:

The sad part is, I'm not 100% sure, yet. This seems like something I shouldn't struggle with as much, but I guess I am.

I'll think about this more, as I go back to my day job.

See you after work...

I guess the negative part of this move is that I strengthen his group. Is that it?

My sense is that R-13 is a dual purpose play, while the approach from the top allows Black to shore up his weakness on the right. Still, you may be right.

It seems clear that the White group on the left side is too far away and that it will work better with a pincer.

Yes, you strengthen the Black group. See http://senseis.xmp.net/?SqueezingOutTheToothpaste

But you also end up weakening your floating stones. Three stones in a row on the E file are hardly strong. They are, in fact, heavy. Better to strengthen your two stones now with a jump to G-14.

See you after work...

The large knight's move is often a mistake, as it seems to be here. White should live with 2 through 6. Black can't play 7 because of 8, so White can play 'a' to live after Black connects.

The small knight's looks like the move, making ko. But the ko does not seem like such a burden for White. White takes first after 7. When Black retakes after a ko threat/response, 8 is an internal ko threat. Again after take, threat, response, retake, White can play 'a' as an internal ko threat, answered by 'b'. If later White decides to win the ko, the play at 'c' creates life via a double ko. Somewhere along the way White can choose to play 'd' as another internal ko threat since there is a White stone on C12 in the game. At the point in the game where Black attacked the corner, though, White is probably better off to give up the corner in exchange for two moves in a row on the outside. There are a lot of large normal moves that White could take advantage of.

A little theory + poor practice dies again!

Bill's look better. I call them Bill's because I can't see a post by Shaddy where he presents them. What post # is that in?

Just to redeem things a little (or make a bigger fool of myself), doesn't White win the fight if he connects below instead of playing C19 in the game? A case of big eye versus no eye?
