tj86430 and I will be playing a no komi game that is open book/database where I will be taking white. Good luck and have fun ![]()
Playing as white with no komi is actually my favorite starting situation. I like it because it encourages me to be aggressive and overcome the opening handicap, but I'm not so far behind that it seems necessary to overplay early on. |

Have a good game I have played very little in the last year or two, so I'm probably even more of an underdog than our ratings would suggest. I'll take this as a learning experience. I have no plan yet, but I'll start with what I'm most familiar with |

What I expect:
I like this opening for white because it feels more active then just taking the last 44. If it goes like this, I expect him to approach my 53 stone, and I'll try to get influence facing the top and sente to approach his upper right 44 stone. |

One possible continuation
I like this opening for white since it feels like the marked stone is perfectly placed in that it both extends from my wall and approaches his corner reducing his potential there. |

I thought briefly about C16, but I decided he can have his shimari if he wants to. Still sticking to what I'm most familiar with. |

a and b are the only two moves that I seriously considered. I'm terrible at games where my opponent and I both build up competing frameworks so playing anything on the left hand side seems out of the question, and that is especially true when I'm playing as white with no komi. After I decided to play on the right side, it was a question of where. c and d were ruled out without too much thought since my approach would be pre-pincered at either one of those moves. This left me with a and b. My first instinct was b and I almost played there without thinking, but since this is a Malkovich game I decided to spend more time analyzing the position then I would normally. After examining the position, I decided to go with a for a couple reasons. First, there's more space on the lower side so a play there would logically be slightly larger. Second my top left corner stone is low along the top so he'll have a harder time making a large number of points there even if he gets the first play there. Finally, if he gets sente and wants to extend along the top, he won't be able to both extend and approach my corner at the same time since his logical approach direction will be from the left side, not the top. As for where I expect the game to go now, I imagine he'll pincer 1 space low and I'll take the corner. I assume this because that's what everyone who plays the san-ren-sai seems to do against me when I approach ![]() |

This should work fairly well with my sanrensei, but we'll see. Other moves I considered:
After a) I don't particularly like white O5. Black b) can lead to a somewhat complex fight if white pushes through at P4. Black c) and d) are the "safe" options. I didn't consider P3, since this favors white, I think:

Is Black trying to improve upon the Takemiya move? ![]()

This move came as a slight surprise since I'm not used to seeing it, but after taking a closer look it's not that different from what I expected. What I expected before 7:
Versus what I expect now:
The main difference between these variations is that he gets to keep sente and I'm not sealed in. This seems ok for me so I'll probably be content to play this out and see what he does next. |

A bit unexpected, but I welcome my opponents move. I have no objection to e.g.:

"]
My normal way of attempting to handle the san-ren-sei is to reduce its potential from the outside which I think I've done an ok job at so far. Since he will probably leave this sequence with sente, I'm not too worried about reading deeply right now since where I play will be heavily dependent on what he does with sente. |

I can't tenuki the lower right since the push and cut works and will allow my opponent to separate and kill some of my stones.
As a result of this, I only considered moves that removed this cut. My main choices were a and b in the diagram below.
The main advantage of a is its security. After a, my corner is 100% secure and is worth roughly 10 points. If the board position were like this I would probably play a.
The reason for this change, is that having this completely solid, low group is quite useful at reducing my opponents potential at the bottom. However, in the actual game my opponent has no possibility of developing the bottom so that's not necessary. Additionally, in the actual game my opponent has invested all of his moves on the right side, so descending to b seems like the better choice since it reduces his potential at the bottom if he tenuki's. |

Still according to previous plan. Some other possibilities:

Post subject: | Re: #211 Adanux vs. tj86430 |
I think my opponent's last move was a mistake and that this is the correct way to punish it. To show why, let's first consider what happens if I tenuki.
If I play on the left, black can enclose the corner and suddenly that area of the board seems difficult to manage as white. Thus, my next move should address this and prevent the double wing. Luckily for me, the 4-4 stone has the inherent weakness of not protecting the corner so I can invade with ease at the 3-3 point. I'll post additional thoughts on this move later. |

I'm pretty busy so I probably won't have much time to devote to writing here for the next couple of days. However, I'll try to keep my moves coming consistently so the game doesn't come to a halt. As for this move, it's pretty obvious and I'm looking forward to see what my opponent does next. The hane is standard, but I'm hoping he plays the knights move so I have an excuse to look at those variations. |

Still happy. I'll try this as an experiment, since there is the possibility to get sente quite 'cheaply':
and then white at ![]() If white plays:
This will revert to "normal" joseki, |

Hey tj, I figured out how to make the diagram display the correct number. After the $$B at the top, put cm19 and then 1 will become 19.
As I'd hoped, he plays the knights move instead of the hane. This is exciting for me since I believe this is the first time I've ever had an opponent play this move. After examining the continuations, it seems like my move here forced and it leaves him with two choices shown in the diagram below.
After looking at a pair of joseki dictionaries and the sgf lovelove posted on these forums, I found mixed results. One dictionary mentioned only a, the other mentioned both a and b, and lovelove mentioned only b. The variation I currently expect is this one simply because it's the one that lovelove posted and I wouldn't be surprised if my opponent was looking at the same thing.
Lovelove claims the variation ends here since a is gote for both sides. However, the dictionary I found that had this variation included a followed by b so I'm not sure if his description of it being gote for white was specific to the board position or if it was supposed to be true in general. Assuming I'm right and this is the variation that gets played out, I'll have to read the situation out more closely to see whether or not I can cause serious damage if he tenukis my push at a. Either way, I'll take sente and probably try to reduce the massive influence I've given my opponent on the right side. |
