Life In 19x19

Posted: **Sun May 15, 2011 4:14 am**

Hi,

This is my first game for review...trying a lot of new things here that I've learnt recently...hoping there's some advice. UNfortunately I lost by 12.5 points...

My analysis is:

Move 81 maybe should have been F3?
Move 99 is a waste
Move 140 was just a bad move...no idea why I made it. Should have connected at G12. This was one of the moves that lost the game.

After that...was mostly over.

Many basic shape problems.
You played a blitz game (< 9 secs/move),
but longer time will not help you so much until you improve your basic shapes:

About move 7, see viewtopic.php?p=36322#p36322

Move 15 is way too loose. It should be around R6 or R7. The majority of your stones have been used to take one corner; after you play P8, he can destroy much of your profit with R6.

Yes, move 81 could have been better at F3. But, whether F3 or G3, note that you are still trying to patch the weakness created with move 7.

Move 140? G12? I assume that those were typos. Yes, 139 would have been better at H11.

This is considered good for black. In terms of territory black and white have come out about even. But since white played in the corner first, he should expect more. If your opponent plays like this (and they will quite often until the low SDKs), thank him in your mind and gladly play this normal continuation.

Conversely, this is good for white:

Because black is cramped and hasn't gotten all the territory he wanted. That's not to say that black shouldn't play this. There is a time where invading is necessary. Just that the local result will favor white.

Thankyou all for your advice and time! It's really appreciated! I will re-read it until it sticks and try to improve those aspects of my game over the next week. This was one of the first games where I've tried to consider shape, so, glad you've been able to point out many areas where I can improve and avoid creating weak shapes. I'll post another game in a weeks time, and hopefully you'll be able to see an improvement.

I'll also try and slow down...I wasn't aware I was playing so fast

my own 2 cents
I am much weaker than the other posters so beware but here is an attempt at rationalizing what i understand:

90% of the time if you want to approach a 4 line stone from below, a knight move is better than a diagonal move
This is true for the hoshi stone but also in general for all 4 line stones

I believe this is important because all games have several of this kind of approach.
In this game you have this kind of move at:
5,8,16 (corner stone) and 68,72 ( 4th line stone on the side)

knight approach is usually far superior. For example:

after the block B stones are ok ans W stone have some weakness ie B can still aim at a .
Not saying that its not good from W but rather it is ok for B.

another W answer is :w1:

at

but B is usually fine also (don't want to put too many diagrams) and in that case the bottom is still open

On the other hand after the diagonal play from below B can play head of 2 stones which can be unpleasant

W gets to chose which diagram he wants (ie W choose whih :w2:

he wants to play)and usually at least one of them is really good for him (her?)

This is NOT to be confused with the shoulder hit, from ABOVE and not from BELOW .

i think a lot of DDk are confused between last diagram (shoulder hit, good) and the diags before ("armpit nudge", bad )

please flame away if I grossly misrepresented the matter :-?

It's nice you're doing this kind of analysis. I try to be careful with statistics like 90% because
of the ridiculous number of exceptions in Go.
