Big Brother Malkovich # 1 (continued)

[admin]
This thread only makes sense in context, so - in October 2012 - I'm adding this introduction.

This game is a Big Brother Malkovich game. To make sense of that...
See http://senseis.xmp.net/?MalkovichGame...and...
See http://senseis.xmp.net/?BigBrotherGo

This game was originally started on GoDiscussions. (http://senseis.xmp.net/?Godiscussions) and when GD died, it moved here. That's why 'continued' is in the title.

The teams are Chew Terr, me, and Shapenaji playing white; Gresil, Topazg, and Violence playing black.

We join the game when it is Chew Terr's turn to make the first white attempt at move 24.

This is move #24A. Has anyone seen Violence, I think he's the only person I haven't seen at L19.

Hey, if I forget to post this in the bug forum, the software doesn't seem to know how to handle nested hide tags.

Okay, let's look at this carefully...

First, I think that Joaz corrected my move to make it more cautious/passive. I still think that the more aggressive move is playable. That means that the result is not necessarily good for us. Because Joaz's move supported our weak western group, I'm betting that he thought that black could attack that weak group to push it low and such. Even if we killed the corner, that would give black huge thickness that could potentially weigh heavily later. I'll try to keep group safety in mind as I consider this move.

I've ordered them by increasing optimism, so I'll save c and d for last. That way I'll at least analyze a and b more fully, as they deserve.

You know how they say that empty triangles are bad because they hurt your liberties? Well. Empty triangles are bad. They hurt your liberties. So let's not make this one.


For novices
What's an empty triangle?

For the uninitiated, an empty triangle is 3 stones of the same color touching, in a blocky sort of triangle.

The white stones here make an empty triangle. You'll see that before I play the marked stone at a, I have three liberties. After the empty triangle, I also have... three liberties. The shape tends to be inefficient because it does not move far from the stones you already have, and does not buy you any more liberties. In tough contact fights, liberties are a huge deal. A hane at 'b' would probably be more efficient because in addition to restricting black's group's liberties, it ensures our top group a bit more eyespace. Whether or not our west group can survive long enough for 'b' to help us capture black will be decided in my analysis of 'b'. If you would like more information on empty triangles, check the sensei's article, send me a message, or ask someone who knows more than me. I am, you know, quite ignorant =D

Okay, we have no good answer to B1. It would be nice to hane at 'b', but we don't have enough liberties for it. Yet.

Now, 'c'

Okay, let's see. The downside of playing here in general is that we're still low, and we're building black an enviable wall. So we want to stop pushing here at the exact moment we can. If black plays 'a' to get more liberties, we can turn the corner at 'b'. That gets our group safety, and makes our weak stone below start to look like an extension, albeit too far. If black plays 'b', we can look at 'c' and 'd'.

First, 'd'. Let's see if the prior push gave us enough liberties to make the hane above.

Okay, so now we CAN capture the corner group, but it gives black huge east-and-southward-facing thickness. I don't think we get enough for it, but at least we won't die. This move is a pressure release that we can use if we get in trouble (or if the thickness black would get is somehow neutralized), but it probably won't be an option by the time we would choose to take it.

Now let's look at the alternative, a hane towards the south.

We can hane at 'a', but then both black and white groups have 3 liberties... and black goes first. The other option with the hane is to atari the cutting stone from the other side.

Meh, this is not amazing, either. If we don't cut off the surrounded corner group soon, black has a tesuji at 'a' to get more liberties. So black would have the option to keep pushing us low like this or to try to save the enclosed group with a play at one of the 'b's.

So maybe 'd'. I've got a feeling that this hane will look a bit like the prior hane diagram, which is scary.

Again, ALMOST enough liberties to win the fight, but not quite. We could play W6 at B7 to try for a crane's nest, but that puts both our group and black's at 3 liberties, and again, black's turn.


If we play 'e', black instinct seems to be to peep at our connection, by playing 'd'. Then, we can play 'c' to connect, but I'm not sure if that's any better than reversing the order and playing 'c' then 'e'. So, after all this, let's just play things the passive way. Let's play 'c' in the first hidden diagram, then plan to play 'e' or something like it, if black keeps pushing us along. I hate playing moves this passive and giving black all they want, but I can't read a better way. Hopefully Joaz and Shape can.

I approve.

Locally, it is the only move. The black hane here is just too strong. And now we are threatening the killer hane at B18. They will probably have to take C18 to prevent it, then we play D18 which is sente, and they make themselves alive in the corner with B18. Then we have sente!

Also, in a whole-board sense, this move follows theidea of reinforcing the important D7 stone.

A no-brainer. I must make life in the corner, but it's all right—white's top group is cramped but weak.

Gresil's last move is the only reasonable move. Both of his older brothers will agree with it. If black were to tenuki, then white kills like this:

Gresil's last move is the only reasonable move. Both of his older brothers will agree with it. If black were to tenuki, then white kills like this:

Thanks Joaz. Always appreciate the work that you put into these (whether the information is meant for me or not).

Actually, thanks to everybody for all you put into these. This game has been especially fun to watch as it unfolds. I look forward to more. :)

For Joaz and shapenaji:
Coming out of this fight with sente, where are you looking for the next move? And, if you don't mind guessing, where do you think Chew might move?

It's horrible having your opponent hane both ends of two stones. Three stones is definitely less painful, but still really annoying. However, the choice is either that or die completely in the corner, so for those that hadn't seen my previous sequences on GD I'm still expecting the following.

However, having never seen this joseki before in any of my games (I really mean this!!), it's come up twice in my games since I realised I didn't know the joseki in this thread. One of them was particularly interesting. Firstly, I had assumed "a" above was the only move that felt correct, but my opponent played "b". Assuming foolishly that pushing at "c" would cause him shape problems (and I could have sworn I had a working ladder) I merrily pushed, and then re-read to find that nothing quite worked. The game started as follows (I've moved all the other stones around to match my game):

Argh, curses, I want to cut, but neither the ladder (a) nor the net (b) work, so White probably escapes both sides:

Yuk yuk yuk yuk!! Still, I'm alive, and I want to cut at "a" if I can - it looks annoying. However, I have a bottom group that needs looking after now as well. Time to protect that, and then get going:

"39" Looks like it's a splitting move first and foremost, but it was really designed to give me good running shape with "41" and "43". It doubled as a splitting move too, and after he got to fix that cut I wanted it made sense to me to take "45". After this the game doesn't really seem so relevant, but the ladder I couldn't play was very interesting, especially as the game we have going White has the ladder available to him, so we cannot play as my opponent did in the game above.

Approved.

So here we are. I'm glad we have F6 now, and I think we'll definitely profit here, as long as nothing crazy happens.

Okay, I have a couple of questions at this point. First, is responding at D18. Can I kill the corner if I do? Do I need to play there to kill the corner (Pretty sure the answer to this one is yes). If I do not respond, is the top white group in significant danger?

I would LOVE to get a move like this in, but I don't want to get our top group into trouble to do it. Obviously this move would give us a big advantage on the left side, but it's not worth it at the expense of the top. Let's look at the answers to these questions, then consider where we want to go to resolve them.

Okay, first question was the move at D18.

Okay, it looks to me like black can live small in the corner in gote if they wish, even if we take D18. Now let's see what happens if black tenukis.

Okay, so B18 kills the corner if black tenukis, but since we can ignore 1 where I just showed it, black gets to do something more active. Let's consider a more reasonable scenario.

Okay, if black tenukis, they seem to at best get a wall facing the center, but our groups on both side live and take low territory on the west. I'd say we come out ahead there, but black does get that free tenuki to approach our southeast, so it is probably even. In short, B18 is sente to kill the corner.

Next up: If we tenuki, how much trouble is the topside in?

Okay, :wc: is sente enough that if black does not respond directly, the crane's nest kills just before black could kill the top. So we assume black will respond. Let's see how that goes, too.

So it looks to me like we, also, can live in gote. I'm not certain I like this, since black gets sente. I could live with the position itself if we had it. So let's look at one more option.

Since F14 is so crucial to the fight (and it would let our top mostly into the open) let's see what happens if we took it first.

Okay. I'm not confident at all about reading anywhere near this deep. However, I am sure that this makes a more complicated fight. Since the best reading I can make turns out poorly (though barely) for us, I believe that our groups are probably too weak to fight this out right now. While my team can correct any misreads I've got, I have to assume that black's team can fix as many of the misreads I did on their side, so our groups will still be slightly too weak to win. As a result, I'm going to pick the road shown in the third hidden box.

Edit: Looking at it later, I think we can do well enough from this is 4 is at E12. While we don't actually have a ko threat big enough to win the ko, we can save the bulk of what was threatened. Hmmm, so confusing =D


Edit: This game hurts my brain. I feel like I'm using diagrams a bit as a crutch to help me read deeper than I could just sitting at a board in a regular game. I'm going to try to cut back on that a bit. That should make it more instructive to anyone weaker than myself, not to mention make it so I won't mess up by trying to read deeper than I really can. That may mean me sticking a bit to simpler variations and such, but I would feel less cheesy doing it that way.
