79. Marcus (3k) vs. Chew (3k) Open Malkovich

Marcus · Post by **Marcus** » Wed Nov 03, 2010 12:55 pm

As I mentioned previously, I had to think carefully about this next move.

One advantage of a game with no time limit is the ability to take time to examine a position like this. Here's the move I decided on:

Here are the thoughts I had:

Let's examine the board again:

The upper left corner is the current focus, but I want to consider the rest of the board, too, in order to decide how to proceed.

keeps Black from gaining influence, while beginning to build some influence for White instead. It is a very center-oriented move (which isn't a bad thing).

Looking at the board as a whole, White is slowly building up an advantage in central influence. If White gets to use that influence efficiently, it will be hard to keep up in central points.

It's now time to break out the toolbox.

My current set of Go Studies revolves around Shape and Haengma. Haengma, in particular, fascinates me because it fits so naturally with how I understand the game.

For those who don't know much about Haengma, see the following mini-primer:

Haengma can be complex to apply, and is tightly tied to the concept of Shape.

First thing I want to do is try to apply Haengma concepts to the upper left corner:

I've drastically reduced the options based on a couple other ideas.

1) Most moves I've selected to consider are on the 3rd or 4th line. These are the two important lines in the opening, and I think most non-combative moves should be on these lines in the opening.

2) I am not considering extensions or diagonal plays. They feel too slow for the current board.

Let's look at the local moves I narrowed down to:

a) One Space Jump to 3-3. This is completely solid. It just takes corner cash, and leaves very few avenues of attack for my opponent to use.

is left as a lone stone, and can be attacked later if my opponent does not reinforce it. However, it's only a small amount of points. I don't believe it is nearly enough to offset the thickness towards the center that White is building up. Something like this could occur:

Looks too good for White.

b) The expected move. I enclose a bit more of the corner. White gets a few forcing moves to strengthen the left side moyo.

The three moves at x, y, and z all feel a tad urgent to me. As indicated earlier, I would probably omit playing x in order to play y and prevent White's moyo from becoming huge ... of course, White is going to pincer a stone at y, so maybe I'll make a long knight's approach instead. Something to consider.

c) The fighting move! This could turn into a mess very quickly. I got carried away in looking at this move. Here's the SGF of my thoughts. In the end, I don't think I'll make this move, but I found studying the consequences interesting.

[/go]

Thoughts continued:

d) The knight's move along the side. I like this move. It's on the 4th line, aiming towards the center. It threatens to live easily on the upper side, right in the shadow of White's wall. Most importantly, it doesn't directly strengthen White along the left side. White is given the choice of taking the corner directly, or making the left side moyo anyways.

The marked points x, y, and z are all possible follow ups by White, or perhaps a tenuki will occur. It's a lot harder to predict what White will do here, because, unlike move c, this move doesn't immediately ask for a fight.

e) Two space jump on the 3rd line. This is like the knight's move, offering peaceful variations. However, it feels too flat. The real fight in this game is going to be in the center. I want to make sure I keep up with the influence game.

f) The only pincer I can think of ... but it doesn't seem very good. Black gets split into two weak groups. Now what?

In the end, I'll go with move d. It seems to fit the style of game I want to play here. I want to set up nice, solid groups with access to the center for the coming fight. I want to avoid both giving White too much influence and getting pressed down and sealed into the corners and sides.

So, I considered a few moves, but I kept coming back to this one. I considered two things most here: group safety and sente. Of course, the two are strongly related. If your groups aren't safe and you have sente, you don't really have sente, because you are almost forced to defend them or suffer. Unless, of course, you can defend your group in sente, often a hard trick. So, let's look at groups. While the bottom two stones can't be said to be alive on their own, they have so much room on both sides that they are flexible, and won't die on accident. Both top-right groups are alive, of course. We both have enough strength to nearly-certainly grab a second eye if necessary. In the top left, both groups are weak. Unless I can find something amazingly urgent or decide to sacrifice my top-left stone/use it as forcing, I'm going to want to play a move locally there.

Looking at a variant of Marcus's last diagram, we see options for both sides. Black can treat something like x and z as miai. White has things like x and something like y or w as miai for safety, plus the option of taking somewhere around z first, as well. I'm pretty sure I'm going to go with x (I lokoed at this for a bit before typing, in addition to tending towards intuition in this sort of situation). So let's look at x last. That leaves my options at w, y, or z.

Starting with z:

The most obvious responses seem to go like this: I framework it up, black takes the corner. However, black settling in the corner removes one of my miai, and I have to give up sente to defend the stone if I still want it. Assuming that, that gives black options, like capping 5 at will. In addition to whatever he uses the sente for first. Despite the large size of the framework, this means that the whole gambit comes back to bite more more than I'd like. While 5 is big for points, it does nothing for group safety. This reminds me of what Bill Spight has been showing lately, about how walls with eye potential don't need an extension. So let's look at options that work from the other side.

Option w is similar to y, but it tries to compromise between helping the top and bottom. Let's look at the simpler y first.

This, while stable, is clearly gote. It leaves black both of his miai options, which I'm not happy with. He can take his choice of whichever seems larger, or wait until the surrounding game affects one or the other before deciding. Option w would do the same, for the same reason. While settling on the left makes it start to look like a framework, the framework is much-limited if black gets sente to approach the bottom left. It makes the difference between a one-wall framework to a two-wall/massive corner framework.

For this reason, I'm going to go ahead and look at the final option, x:

This move actually affects black's miai options. Seemingly he must take 'z', or be pincered and chased while I seal the top. This move, unlike the others discussed, settles me in one play. Additionally, though it's only a handful of points that I nab, it makes me fairly hard to attack. That means that this is the only way to emerge with (as far as I can see) both safety and sente. While it pains me to give black the big move on top, I can hope to get something like L17 or M17 later, two or three lines shorter than the option at 'z' I considered.

Assuming the logical continuation by black at z, I have tons of options.

I'll look into some of these after we see if Marcus plays on top as I'm expecting.

The top side is uninteresting, I think. Pushing on my opponent's moyo potential on the left seems essential here.

Unlike my opponent, I don't think his upper left group is completely settled. He could potentially tenuki here, but that leaves me with a lot of possible moves to ruin the left side.

I want to talk about two local moves that White could make (a and b).

The first one is an attack from the right side. If White plays at a, I will likely begin a contact fight. Something like this might occur:

Granted, White does not need to play

and

, but it does make a large gain on the let side. In exchange, I'm building up central influence, which was the point of my

... White has been reduced to making territory directly using his wall in the upper right, and the peep at x is becoming more interesting ...

The second local move I wanted to look at was the simple extension (b above).

looks slow, but it feels very useful to me. Separating the black stones looks pretty difficult. My access to the center remains strong, and approaching this group from the top right doesn't seem as urgent as some other points on the board, especially playing under my 5-4 stone at y.

So, what if White tenuki's?

It's quite possible that White feels like his group is fine. in that case he'll play something like

at Q3. I can't say this is wrong, as it is an important point to attack. However, the points at w and z can be exploited later by Black to reduce the left. The important thing will be to try and wrest sente back to take advantage of it later.

It feels like there are two aspects to this battle over the board: central control, and maintaining sente. It's an interesting fight. That being said, this move is likely going to get a bunch of criticism from observers, I bet. It's definitely not a joseki move in any sense.

My opponent's move is surprising to me. It is forcing, sure, but I think it may be better for me than my opponent. I had shown the expected K17, to make a base, right? After my opponent's last move, he still has no base, so will have to keep running or get a base, eventually. Let's change the order of moves. If he made a base, would he still exchange 21 for 22?

After B makes a base with 6 here, I think that he's more likely to break up the left side with C9 later. If I were on the third line, I could see pushing on me to keep me low, but here I'll be happy to jump along the fourth line, and aim to cut away black's base, later.

Don't get me wrong, the last move isn't horrible or anything. It just seems like a slightly unfavorable exchange, or aji-keshi, or something.

As far as my move, I'm treating it as forced. Don't want to get sealed in, which would make my opponent's kind of weak group strong. My opponent has sente, but I still expect him to make a base on top. If he does not, I can theoretically get big points on top in sente, which seems unreasonable. The other two options my opponent has are approaching the bottom left or enclosing the bottom right. I just think the top is currently biggest.

Sorry for the delay. Busy weekend with family in town.

This move is pretty hard to resist. As far as why to play locally here, every other area is more or less settled, so this area has the highest returns for investment at the moment. If black gets to play again here, he gets a perfect enclosure. Now, if black takes an enclosure, I get a stable shape (or at least a forcing move) facing my own growing framework. As far as why I choose this specific play, my opponent and I are both doing our best to build up and out. As a result, I want a move that will be high (for thickness) and towards the left, to work with my own framework. My opponent has an awful lot of potential territory, so I have to be careful. However, if I can limit what he gets on the right and get something reasonable below myself, everything still looks okay. What ends up happening here is dependent at the moment on my opponent, but as I play, I intend to keep in mind that I want both thickness and framework in the south. Choices that I make locally will try to work well with that. I do not expect a pincer, because that would let me do stuff like claiming the corner or double-approaching the 4-5 in his precious moyo.

At the moment, I'm not sure who will end up with sente from this region. However, I'll start looking at nonlocal moves I hope to get in.

a: This is huge. it's not a safe way to build on the left, but it's so fast and large-scale that it's worth the looseness.
b: Starts to make the top left look like territory, and supports the bottom.
c: Starts to defend the corner, while working on preparing the left. Whether this is important depends on how big the 3-3 invasion is after the bottom right is resolved. If my group reaches the star point or so, the invasion gets big, so this move is also bigger. Obviously, this knight's move can be in the other direction, depending on which side needs more support.
d: Risky. It's too early to invade deeply, though there's the option. The slide at S13 is sente because it threatens to save my dead stone, but that's obviously insufficient to live on its own. The right location to invade also depends on how the bottom right resolves. If the bottom right is super-strong, I may not invade low, I may reduce from high. Or I may keep putting it off, and not get the chance.
e: Points, and extra stability. Don't need it yet, but it's fairly large if I get it eventually.
f: Small at the moment, but good for thickness and preventing my opponent from ever getting much more here. 'a' is unquestionably better, though.
g: We'll have to come back to this fight eventually, but we can't yet. I think we would both tenuki it if played, so it'll have to wait.

Obviously, these are only a few of the possibilities, but it gives me a reasonable idea of what to expect.
Okay, I was torn between 'a' and 'b' for a while, but I think both are probably fine. However, I kind of like the look of 'a', though it kind of offers up my corner, if my opponent wants it. It pressures well and makes the double-approach hard, so most of the possibilities seem fine for me. Let's see what happens! Also, when it comes down to it... if my opponent is afraid of my moyo, perhaps that's the best sign that I should expand it.

I apologize for the delay. I've had a rough week, and I'm not familiar with this move. Trying to find a way to turn it into a mistake for you.

No rush, it's a really busy month for me. Additionally, don't worry about making my moves mistakes, I do that well enough on my own. =D
