I say even ![]() ![]() *checks* Looks like I'm black.
Good luck and have fun! So, how y'all doin'? Let's talk a bit about my opening ... I'm not very good with it. I seem to have two modes of play: local and overplay. It's time I tried something new. I think I'll try playing a Nirensei opening. |

Have fun! ![]()
I instinctively opened your hidden comment and then quickly closed it again, when I realized, that I'm not supposed to read your comments in this game! ![]() Let's leave him the choice of playing a diagonal fuseki! I don't have a plan for the opening yet, but I don't want him to get a big moyo! I'm not good at reducing moyos! |

Heh, not to worry, it was only a comment about the perfect move. ![]() Feels odd to play this opening. The 4-4 is supposed to be flexible and quick to develop. I personally am much more comfortable with the flexibility (and complexity) of the 3-4. However, I keep saying in these games that I want to try and play a solid and calm game. It hasn't happened yet, so maybe this will drive the game in a new and (hopefully) more peaceful direction. ![]() |

This one – compared to D3 – does not give black a perfect approach to my corner! I didn't want to play another 4-4, because I don't like the symmetry and I also want to make him approach my lower left instead of playing sanrensei! |

Post subject: | Re: 60. Marcus (4k) vs. Zwergesel (3k) |
The question is ... should I approach high or low? Playing on the 3rd line in the opening is a territory-oriented move, usually. I've had some success lately in trying to play a balanced game in the opening, trying not to keep the number of 3rd and 4th line plays roughly equal. Since I've played two 4-4 stones in this game, I think I'll try playing the low approach. I should be able to end in sente and make another big move. One thing I should probably avoid is over-zealous tenukis like in my previous Malkovich game against Redundant. I took some pretty big points, but left my group horribly weak, and gave Redundant multiple groups of stones he could then attack for profit. Since I want a solid and peaceful game, I should try to keep the number of weak groups I make to a minimum. Easier said than done ... |

Let's play peaceful here! Getting sente would be ideal! |

Alright, White is playing a peaceful move. To be honest, I thought I'd be pincered. Here's what I hope will happen from here. It's a pretty common continuation.
I get sente back with ![]() ![]()
I'm not sure where I'd go after this ... Is 7 worth protecting at this juncture? Do I try a tenuki? Where? I'll have to think about it if it comes up. |

I don't know much about tewari, but this might be an example of it! In case he plays the natural response E4, then his marked stone looks misplaced!
This is the same as if this sequence is played, in which you'd rather play ![]()
Let's see if he has a different response prepared ![]() In any case, D3 gives me a solid corner and a follow-up at E4 if he tenukis! |

That was unexpected. Can't say it's wrong, though. As Magicwand is fond of pointing out: "one stone is aji". There are a few ideas that went through my mind when I saw White's move. First of all, it's usually a good idea to respond to a kick:
I'm sure we've all seen this before. ![]() ![]() ![]() What about in the game, though?
Look at the ![]() ![]() ![]() ![]() ![]()
I admit ... ![]() ![]() Still, E5 doesn't look bad. However, that's just the first option. I can think of at least one other:
I THINK this is considered a "wedge" though my terminology might be wrong. I'm "wedging" between ![]() ![]() ![]() In all cases, though, I think it is White's turn to tenuki now. He's secure in the lower left corner and ![]() |

Post subject: | Re: 60. Marcus (4k) vs. Zwergesel (3k) |
This looks strange! I'm going to pull my stone out, because it is sente (threatens to cut his group) and because if I tenuki and he plays there later, his group becomes really strong! If I save my stone, it's weak – not weak enough to be killed, but weak enough to make profit by attacking it! |

Post subject: | Re: 60. Marcus (4k) vs. Zwergesel (3k) |
I'm connected now ... and I'd say I'm pretty settled. I'm not sure I agree with White's move here, but I can't really find a fault in it. I'm forced to settle my group, so White keeps sente. However, I'm still not convinced that White's G3 and G4 stones are very valuable, and he's forcing me to make my more valuable group safer by threatening to cut immediately. It's a minor thing ... maybe I just like the idea that White could play at ![]()
I don't like wasting aji. ![]() Moving on, looking to the future moves, the bottom no longer looks very appealing for White. Black has hunkered down and made some territory there, and the bottom will have to be shared between the players (boo! I want it all! ![]() So, what's left? Here comes a whole bunch of lower-case letters!
First, I want to talk about 'a' (C8). I have watched a few lessons on KGS given by shygost, and one of the things I've taken out of those is the idea of "finishing" a local play. The idea is that a local group is "unfinished" in the opening unless to extend to a point on the 3rd line. The reasoning is that if you leave a group with a termination point on the 4th line (like ![]()
Let's compare ![]() ![]() ![]() ![]() ![]() ![]() Now look at the lower left (around ![]() ![]() ![]() Back to the game:
White could stretch out towards 'b' (C10) to try and "finish" the local plays. While it feels like a big move to me, White will not keep sente that way. Considering 'c' (O3) is a big move for Black, White will want to make sure to get as much out of the next few moves as possible. In addition, the attack at 'a' is just not very profitable for Black yet. There are more open parts of the board to play in (more on this idea in a moment). Playing at 'c' himself, or at 'd' (Q10), or even the wedge at 'e' (K17) are all fairly big, but again do not keep sente. The moves 'f' (C14) and 'g' (R14) make more sense to me for White to play. As Black, I will try to regain sente if I can, but I feel at this stage of the game it is important for me to respond locally to either of these. White then gets the chance to fight to keep sente himself. So, which will he play? There's a common wisdom that says you should "play away from strength" in the opening, which refers to both your own and your opponent's strong groups. In addition, the most open side is the right side. The idea behind playing in a more open area of the board is that they provide the most potential for gaining points. Each move you make in a local area has less potential to make territory than the previous move in that area ... it is naturally limited by the potential of the previous local moves, and also puts its own limitations on the potential of those previous moves as well. To make your stones as efficient as possible, you want to spread your potential across the board as much as possible so as not to fall behind your opponent. This is a difficult idea to use well, since it's not easy to calculate potential, and when your stones are weak they can be attacked and exploited by your opponent. Trust me, I may know the theory but in practice I fall flat on my face when I try to apply it, more often than not. Given this idea, though, I suspect my opponent will play at 'g' (R14) because it is the more open side and may allow him to take a nice bit of potential there.
![]() ![]() ![]() ![]() I've rambled enough. Let me know if there are any questions! |

Zwergesel: Could you clarify how L3 is putting pressure on his group ? Where does he need to respond ? Why it's big/sente compared to eg. playing R14 directly? Marcus: Nice comments ... Noon UTC+12 is good for me for our tournament game, btw, weekdays. Tomorrow possible for you ? I need to know a little in advance! |

He does not need to respond in order to live, i.e. I cannot kill him with my next move, but if he ignores it I think I can chase him around starting with K2 and make profit on the right side in the process! If he does respond then I think that L3 makes an approach to my lower right corner less desirable! The more I think about it though, I think you are right that I should have played at R14 immediately! I often tend to leave out important moves for moves that I think are sente, but really are not ![]() |

It's Canada Day, and I'm too tired to think. ![]() Another move that I did not anticipate from my opponent. I'm trying to decide between a few moves, but I want to move with a clear head. A few of the moves I'm contemplating: one space jump to the center (J5), settling contact move (L2), and tenuki (R6 approach to his corner). I still think White should have attacked with R14. This move seems slightly unreasonable, since I'm already settled (I don't think I'll have any problem living at all). Once I get the chance, I'll explain my thoughts more thoroughly. Loons: Obviously, I did not get your note until right now. ![]() |

Post subject: | Re: 60. Marcus (4k) vs. Zwergesel (3k) |
I'm trying to take this Malkovich game more seriously and write out detailed thoughts. I'm trying to incorporate a bunch of new ideas into my gameplay, and writing them out seems like a good way to sort them out and make useful applications to my game. Ok, let's see what's going on here.
For some reason, my first instinct is to make this one space jump at 'a', running into the center. As soon as I think about that, though, I can just see Bill Spight posting "Jowa says don't run" ... ![]() ![]() So, let's not immediately jump out. Instead, let's examine my options. First, my group is already very solid. Any pressure ![]() What I need to do is make a plan. First I need to loosely decide how I expect the game to go, and choose a few moves that I definitely want to get. Let's look at the board:
We've had our first exchange in White's lower left corner. I call it White's corner, because White played in that local area first. It is natural for White to get more cash out of this corner, since White should never have fewer stones than Black if all plays are made locally. Now, with both groups mostly settled, the question becomes how each group can be used. White's corner looks like it should be able to naturally expand along the left side. Before ![]()
I chose C9 ( ![]() The timing isn't right for C9 right now, though. The board is still very open, and White can build some great thickness towards the center or take a lot of profit in the upper left corner. I need to make sure what I gain from playing C9 balances what White gains from attacking C9. In order to time it right, though, I need to have sente at the right time. We'll put C9 aside for now. The two biggest areas of the board are the top and right sides.
K16 or K17 would be huge, but I'm not as concerned about getting this point. It doesn't look like this game will turn into a moyo game, so I want to look at countering whatever strategies my opponent has instead of simply taking big points wherever they are (I'll take it if my opponent gives it to me, though). That leaves the right side. I'd like to approach his Q4 stone, and would likely do so at R6. Of course, with ![]()
I do keep sente, so it's not a bad an exchange for me, but White gets a good wall facing an almost ideal extension. White gets to use his L3 stone well, and my Black group is looking more and more swallowed. Maybe I should step back and look again at Black's bottom group. There's a piece of wisdom that says you should try not to get sealed in. Right now, my group is not sealed in, and has potential towards the center in a couple places:
The ![]()
I think these three options ('a' to 'c') are reasonable to consider. First, the one space jump:
Way up top, I mentioned Bill's "Jowa says don't run" advice. If my bottom group was weak, this one space jump would definitely be considered running. My group isn't weak, though. In this case, I THINK I'm breaking a sector line. I don't really know, because all the information I know about sector lines is what I've gleaned from reading posts on L19 and GD. So, perhaps I have the concept wrong. However, I do think that D6 and L3 form a sector line, and jumping like this breaks that sector line. It also keeps access to the center for my group, which is also important, and threatens to capture those two stones sitting on my wall. Eventually, capturing those stones will be worth quite a bit and White will either have to concede them to me, or will have to spend a move to save them. Either way, I can profit from it. My only issue with this move is that it seems to give White exactly what he wants: I'm responding to his move so he keeps sente and dictates the flow of the game. ![]() Next option, settle with L2:
This looks great to me. It's simple, feels natural, makes my group completely safe, and because of the cut at 'a' it should be sente (though I bet my opponent would at least consider tenuki from here). However, Black is still under threat of being sealed in on the bottom later on in the game. Final local thought is to pincer White's stone:
The pincer looks interesting. It reduces what White was trying to gain on the lower right. However, there are so many variations, and I can't be sure I'll come out with the sente that I want to have. Too often I discard the natural feeling move for something complicated, like this pincer. I'm going to play the natural move to settle at L2. Possible continuation of the game:
This is what feels natural. Of course, White may block in the other direction after the jump to R3 on this board:
I can't see this as bad for Black. Cash in the corner, a group of White stones at L3 to attack, and no weak groups for White to easily exploit. White can attack at 'a' and try to make the right side into profit. I'll have to think about a response if this is the board we reach. Now, watch as my opponent plays tenuki immediately and throws all my thoughts out the window. ![]() |

This move smells funny to me. It looks like B is asking to be sealed in. |
