Game Review Flashcards
Lee Changho (b) vs Nie Weiping (w) W’s middle is looking a little scary but B should be ahead by ~10 pts. How should B reduce safely?
1 threatens to cut and take even more. B comes back to make sure there’s no tricks in this area and can safely move in even more
Lee Changho (b) vs Nie Weiping (w) B is ahead by ~5 pts. How can he tidy the board?
Either B will either end in sente and start moving in with B or if W cuts on the inside, B can break in at A
Lee Changho (b) vs Nie Weiping (w) W has played the losing move. How can B punish?
Black asks the question, how do you want to connect? B can connect under afterwards
Lee Changho (b) vs Nie Weiping (w) B is getting pincered, what’s a simple response so he doesn’t end up with a heavy group or giving too much influence
Just settle the other side first. You don’t need to respond to a pincer directly or jump in the corner to give away influence. B even plays Tenuki again
Lee Changho (b) vs Nie Weiping (w) B wants to restrict W on top while expanding. What’s a good asking sequence?
Park Junghwan (w) vs Shin Jinseo (b) W is trying to get influence in the center. How can B take sente to get there first?
B doesn’t absolutely need to defend A right now because he can capture if W cuts or go left toward the ponuki
Park Junghwan (b) vs Shin Jinseo (w) Where does B play next and why?
If B plays the normal extension they’ll get pressed down at 31
Park Junghwan (b) vs Shin Jinseo (w) B53 looks normal but it’s an overplay. How does W punish?
B can’t capture because of this variation
Park Junghwan (w) vs Shin Jinseo (b) How should B respond?
Crawling is not good. The single B stone already served its purpose and is better to sacrifice
Park Junghwan (w) vs Shin Jinseo (b) Where should B’s response be?
In this situation this is better than allowing W to get the corner. Focusing on the bottom toward the other high stones would in exchange for the corner would be a bit over concentrated
Park Junghwan (b) vs Shin Jinseo (w) What’s the most active way for W to get access to the top center?
Lee Changho (b) vs Nie Weiping (w) - 1/15/2021 B can keep breaking in safely while keeping the pressure on W. Where’s the tesuji?
W has too many weaknesses so B can get back out. W’s top group isn’t totally alive either.
Lee Changho (b) vs Nie Weiping (w) - 1/15/2021 W is aiming for something…
Don’t get distracted from the biggest group. B can still get back out or break through.
Lee Changho (b) vs Nie Weiping (w) - 1/15/2021 W is aiming for something…
Don’t get distracted from the biggest group. B can still get back out or break through.
Lee Changho (b) vs Kataoka Satoshi (w) - 09/22/1996 W wants to attack but B defending right now would be heavy and inefficient. What's a more efficient way?
Threaten to make a big area while reducing W. The 1 stone is small right now
B is not alive. W to live clean.
X is a mistake
O is a mistake. Kill B and end the game`
O is a mistake. Why?
A or B are better. The side is too open if B plays hane
Tenuki is a mistake…
B should kill now and end the game
B to kill and save
O is a mistake. How can W take advantage?
Poke the shape point first
O is rushing. Where should W have played?
The normal extension. B can’t take the whole area in one move
What’s the most efficient way for W to settle?
Just cut now. Capturing and settling is very efficient since it takes pts from B and gives them to W without aji
This is a mistake. Why?
The shape point is here. W jumping out makes no points
This timing is wrong for W. Where should it be?
W needs to separate. If B plays there it’s painful to have to live inside
How should W respond?
If W just connects, B has way too many cutting points
How can W deal with A efficiently?
What’s the easiest way to handle?
Just jump! It reduces the right side and puts some pressure on B’s left group
What’s the best way for W to make shape?
Going through the obvious elephant eye! It’s really hard to kill W and it breaks B’s right side
What’s the easiest way to settle if B kicks?
Capture B
Win the capturing race
Don’t rush to fill liberties, make eye space first!!
B overstepped and didn’t defend the left middle group. Where’s the shape point to counter?
W to respond and fix the corner shape with the least aji
Don’t drop down and make a square
W is ahead by a lot. Does the corner need a response?
NO! Now is the chance to deal the killing blow
W is well ahead and there aren’t places left for B to make points? How should W clean up the board?
Just play the shape points to make sure nothing dies. If B doesn’t kill something W will win
Lee Changho (b) vs Takemiya Masaki (w) - 2/06/1996
How can B deal with the invasion?
Don’t have to answer directly. You can decide later and leave it as W’s burden. Invading the corner has the double purpose of destabilizing W, taking pts
Where is the follow up move and when is it appropriate?
Immediately. Living by grabbing the territory is huge compared to having to live on the side
Where is the follow up move to attack the 3 stones?
This also makes a lot of potential on the top right
Which is better direction?
How should B respond?
The kosumi takes care of the peep, separates, and aims at the weaknesses
This is a mistake. How can B punish?
A isn’t sente. How can B connect if W tries to cut?
Where is the shape point for this group?
This sagari looks slow but it’s big. It make the W group into influence and takes points without strengthening B
C looks normal but it’s a mistake. Why?
The direction is wrong. W can’t make potential there
How can W invade this group?
The wedge at 3 is the key move
What if B plays here?
W should make a weakness and go down. Then he can connect back at A or cut at B and break out at C
How should W follow up on the left?
Push and ask first, then go fix. If B tries to peep, W can capture the B group
This is an overplay. How can W punish?
B can live but it’s painful. W has influence and sente
This is a mistake by W. Why?
The square stones are attacking the triangle ones now! :(
How can B take care of these while making points?
B should go up. W has no base now. When W goes out to protect, B can also protect in response naturally
Where is the most important place in the fight?
Not touching directly, but think about the direction that makes points first
If W turns?
B can just take the corner. The area on the other side isn’t that big
What’s wrong with this move?
Later there is this kind of aji
If B is worried about this cut, how should he protect?
Take the corner with points and threaten to connect underneath. If w blocks, then B can protect in the middle.
Which move is best to settle without making a heavy group?
C is best to fight. At least it’s a running battle instead of a heavy group for B only
W ignored 1 to play here. How should B continue?
The top isn’t big since there are 3 areas to play. B can continue on the bottom making W respond
Where is the key point to play for white?
1 and 3 are key to protect both sides in sente
