Post subject:  A way to improve reading skills 2.0

My opening game is strong. But I need to improve the middle game and the yose.

To improve my reading I need to consider intuition, depth, speed and accuracy.

In this thread I will collect whole board problems (blunders) from actual games.


Problem 1:
White to play.

White has a big lead in this position, but the next moves can be decisive. There are several possible lines. As always most lines lead to defeat. I managed to choose one of these :lol:.

If you like to post your line, I will rate your success afterwards :tmbdown: :tmbup:. (The best solution will also be posted later.)

Have fun

a is a strong line, first variation:
(In the real game I stopped my assessment here and dismissed the line for white. Did not visualize the continuation.)

Conclusion:

Moves a, b and c are all viable moves.

When I first reviewed the game, I thought I made a blunder by choosing move c over a.
But the real blunder was move 4 in the last diagram.

After a second look I realize now not the depth and speed of my reading were the main problem. My reading was just not accurate. I have to change my personality :shock:. I am still a sloppy reader ;-)

White: bottom left 15, bottom right 10+, left 6+, right 5+, komi 6 = 42
Black: top left 10, center+left 10, bottom 5 = 25

Indeed White leads on territory.

Black is very thick at the bottom and rock solid top left. Center and top still have some fragility but not much.
White on the other hand has the two marked groups, which have been split and potentially afloat in the centre.

The circled stones are close to the thickest black group and can be sacrificed. I'd say MUST be sacrificed.

At the top there are many questions to ask:
- Black A is huge, taking territory while attacking
- but White B can dislodge black's stones

Sente looks very important.

So here we go:

White simplifies. Black gains corner territory but loses strength in the middle.

White's not totally alive, so black can expect a lot of territory in the marked areas.

But a bigger problem seems to be white's group in the center:

I feel like playing something like the move above.

Either way, white feels a little busy. I think I prefer black here.

No counting or anything - just a feeling.

White can play at 'a', but I agree that that sucks.

I have to admit that I didn't read much, and I'm rusty these days, so the move may not be good.

Here's my take:

My first instinct was to go with C because this secured territory and would force a white response probably to E14:

$$ +---------------------------------------+[/go]


However, E14 is a very valuable move for white. Given that white only had secure territory in the upper right, the left is extremely important. As it stands, white's territory on the left is not completely secure, but it's close. E14 does several things for white -- it would weaken the upper left by making the 3-3 invasion more effective, it would expand the white moyo, it would help strengthen white's grip on the left-side territory, and it would limit black's potential for a framework on the top (white would be playing at the intersection of two moyos). Since C and D allow E14, but lack the same significance. So, they seem like poor trades.

A and B would both limit the value of E14. So, which is better? B will develop black's moyo and limit whites, but in the process, white is going to strengthen along the C and D files. A, however, avoids the contact and thus does not directly strengthens white. Plus, A more effectively expands black's potential moyo at the cost of white's.

So, I'd go with A.

c is the most often played move in my pro database (in this local position). (13x) (Congrats Blindgroup :tmbup:)
d is played 8x
e is played 8x
f is played 4x
b is played 3x
my "blunder" a is played 0x

Zen 7 is suggesting that a,b,c and d have about the same value (whole board) (Zen also likes Q18).

I think c is most often played because it takes profit at once, it has good follow up moves and it avoids further complications down the line. Similar b and d strengthen the black position in the upper left. Move a is not a bad move but a bit loose compared to the other moves, probably there are more ways for white to mess around later.

Bill`s move is also around the same value as a, b, c and d.
