Life In 19x19

Well, the titel says pretty much everything. My opponent was a 23k? on kgs, but i felt totally overwhelmed. I went through the game afterwards but couldn't find ways how to stand a decent chance.

An explanation what was going on there would be much appreciated!

Hi Hrabanus,

Welcome.

How many games have you finished, approximately ?
Less than 50 ? More than 100 ?

Yes, this shape is not good. P17 is a shared vital point.
"Shared" means it's good for B if B gets it,
and it's good for W if W gets it.

M17 -- save AND reduce B's liberties
( your idea of L16 does not reduce B's liberties. )

After this move, you get a bad, broken shape for W here.
See also Toothpaste.
This result began with ,
and ended with when you allowed B to capture the important cutting stone .

Wrong idea: your R16 group is already alive -- lots of eyespace in the corner.
To improve, you need (a) more experience (thus the question about your total number of finished games;
and (b) Life-and-Death exercises.

Wrong shape. You cannot connect with this move,
or any other move here, if B replies correctly.
To improve, you need to expand your knowledge of basic shapes.
( Again, your experience is important for this level. )

Wrong shape. Same problem as -- you cannot accomplish your goal here because your knowledge of the shape here is missing.

- This exchange and shape: Classic Toothpaste.

B can hit the shared vital point J14.

Shape problem ( see ).

This doesn't work (too late).

Vital point. See Elephant's eye.

Wrong shape. B can push at C10 and your local shape collapses.

was too small, too slow -- your 2 stones there are completely unimportant.
You had a chance to fix your shape with D10.

If you have finished much fewer than 100 games --
( example: less than 50 total games ) --
I suggest you finish 100 games as soon as possible.
All board sizes are OK; but you can reach 100 faster
with more games on smaller boards ( smaller than 19x19. )

If you already have finished 100 games,
then continue to have your games reviewed,
continue to do Go problems,
continue to review your reviews -- Repetition is important.

See Mr. Kaz's blog on Go.

Thank you very much for reviewing my game!

About 20-25, i agree totally about the lack of experience.
Usually i ask the other player for a (short) review, i profit a lot from that—besides playing them of course.

review your reviews

Do you mean to go over them again by myself? I already do that, because i often don't get everything in the after-game-review.

I think i understand your points as far as it is possible for me at my current level. Especially the toothpaste/small gap was a eye-opener! I’ve been aware of that mistake for a few games now, but couldn’t avoid it. Today i played two much stronger players (1k+10k kgs) and made this particular mistake a lot less.

Next month i’m going to buy a tsumego book (Graded Go Problems …), until then i’ll continue with L&D + tesujis at goproblems.com.
