Post subject: | 17 kyu vs 14 kyu: a close showdown! |
With this very close game, I've now reached 16 kyu on OGS, which isn't that important but it shows my continued progress up until now. I'm very happy to beat a 14 kyu, because it means that I'm definitely not at my rank by accident and that my increase in strength is not only in my head ![]() Anyway, I've gone over the game with Leela and I've also put some notes in the file, where Leela thinks big mistakes were made. Unfortuntately I'm not strong enough to interpret them correctly, so help is definitely appreciated! I think it's one of the best games I've played so far. Maybe not because of my actual game (there were some big mistakes and some missed opportunities), but because I managed to play it real calmly (not easy for me live) and my opponent was rather aggressive, a playing style I usually don't do well against. All in all, an important game at this moment and I'm glad to hear your opinion about it! [First comment at move 125] EDIT: I'm really overusing this subforum, my apologies. In the future I'll try to limit my threads and either combine several games in one thread or post my games in the study journal or something ![]() |

9: When the opponent makes a contact move, your first thought should be to hane (F16 or D16 here). Your second thought should be to extend (F17 or D17 here). The heuristic to decide between the two is to ask who is locally stronger. If you are, then hane. If he is stronger, then extend. There are tactical exceptions to this, but generally it is a good rule. In this case, you are way stronger because of your extra stone at C16. So hane. Once you have decided to hane, then the question arises: which side? The answer to that is a bit more vague. Then you are looking at not only tactical issues, but concepts like over-concentration. Fortunately for you, the tactics here are simple: if you hane on the outside, it is a threat to kill with a ladder. That makes it good for you. The options of extend/hane and left/right leaves four possibilities. ( Tenuki is a fifth, of course ) Since there is not yet anything on either the left side or the top side, the focus on a particular direction in the second and third diagrams is probably premature. ------------------------------- As I mentioned earlier in the post, there are tactical exceptions to the rule on handling contact moves. Most of those exceptions fall into the category of sacrifices, when the contact stone is a nuisance, and you have to kill it, and while you are killing it your opponent is getting some other benefit locally. I such instances, the question of who is locally stronger is overridden by other concerns. An example is the well known probe against a low shimari: |

As long as other poster's threads don't get scrolled into oblivion, you are doing no harm. 2) I don't recommend multiple games per thread in this forum. Once you post the second game, then the thread becomes hard to follow because there are two separate subjects. Generally, a thread should have one subject. 3) A study journal is entirely your choice. Then it is your thread to make as complicated as you wish. |

At move 211, you can block at A8. Usually, you can't, because of this sequence : But here, it doesn't work : And here, WHite can't play at a, and if he continue to push with b, that doesn't change anything. |

A few top of the head comments. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() I understand, it is a DDK malady to focus on a small region of the board and beat it to death. But it takes only a little awareness to get out of that bad habit. Something that worked for me was to take a second or two and look at the whole board before making a play. By doing so I gained four stones in one week. ![]() Good luck! Edit: ![]() ![]() |

@Joaz: Thanks a lot for those diagrams, that's really practical advice! It was something I had not really come across before. Yes, paranoid seems to suit my style of playing a bit too often, have to work on that ![]() @Bill: Hmm yes, it's something I'm aware of - and sometimes don't fall into that trap. Yet sometimes when you get going in an area you want to use all you can get, while you're there. I understand this is not good go-playing and you should leave an area alone way faster. Sometimes I'm smart enough to remember it and those games do go best, obviously. Other times I get caught up in the moment and I deserve to be punished for it ![]() That's the thing hardest about playing an actual Go game: you can have like 100 great things in your head, that'd make yiy a fairly good go-player. But you have to remember them while playing, and for some reason, that usually doesn't happen ![]() The (not doing the) hane on the 2nd line is probably a bad habbit of mine, but one I had not been aware of before. It's something I haven't spend any attention on studying, too, so a bit unfamiliar territory for me. It must be more important than I realized. Again, I learn something new this game. Thanks both already for pointing me towards a better play. It's also great to see my game review thread of a month ago being of a 22 kyu, and now already 17-16 kyu. Means I'm still developing well and having my games reviewed here is definitely a part of that! Even though I end up making (the same) mistakes again at times ![]() ![]() |

I don't have anything to add to the excellent comments you've already gotten, but don't feel like you're crowding the forum with these posts. This site has always had the majority of content generated by a few active posters, and good go related content is always welcome! These are very useful threads, too -- I'm a bit stronger than you, but I still make plenty of fundamental mistakes. It always helps me to see basic moves and attitudes reiterated; it can serve as a healthy self-assessment for when I wander from the fundamentals. |

About move 125: A quick estimate of territories shows that you are behind in secure territory. You are about even on the top, you are ahead on the right, but your opponent is way ahead on the bottom. In net, you are behind. The only place left for you to make enough territory to win is the left/center. To do that, you must hold the three triangled stones. If they die, then the circled white stones are connnected to their friends on the top side, and they invade much of the space that you need to win. The easiest way to do that is like this: Note that the stakes are so high in the center that Leela is willing to sacrifice your D18 stones - and you should be too. BTW, white cannot capture the crucial C16 stone with the other atari. He runs out of liberties first: |
