Hey, we'd like both sides of this reviewed if people have the time.  We were originally 14k and 19k respectfully when this game started but both having very new dgs accounts our rank is fluctuating a lot. Handicap is 4 as we're carrying on a series of games from KGS where the handicap goes up or down one depending on who won the last game (I forget the name for this kind of series).

I liked the game, both sides played well. I analysed it for my own fun, but I share it in case it is useful for you. W is maybe a bit overactive but that is understandable in a 4H game. Here too many comments and variations. It is overkill. Pick the ones that seems useful and skip the rest. Some coincide with jts'. But apart from one move mine are independent. edit: the attachment only seems to be invalid. You can download and open it to see there is nothing wrong with it.

I keep expecting the last post to be the last one and thanking it but it feels like spamming! EdLee, thank you and for anyone else who reviews this later thank you in advance. |

One short comment in addition to those already given: At move 2, the tsuke (P3) is usually considered good, if black already has a stone around K4, because white can not extend as far from the two stone wall (O3/O4) as he would like. In the actual game when there is no such black stone, Q6 (or R6) directly is usually considered better. In the actual game white got the extension he wanted at move 5 (K4), and thus moves 1-5 slightly favor white. All this is from what I have been told, so if this is not correct the blame is on my teacher.  e: added a smiley to avoid further misunderstandings |

What I found interesting TJ was whether the statement meant that one should not interpret the advice to play the tsuke as a universal approval of the approach rather than an admonishment not to play it when K4 isn't there. (I could be very wrong!) At the moment my only reason for playing it is because I like the shape at the end and I think the exchange of a framework on the side for white versus a corner and a smaller framework on the side for black is pretty reasonable at my level and if my opponent neglects the extension to form a base (it happens around 17k) I have a very nice target. I don't think small edges for white or black in the opening really mean that much for weak ddks similar to how in chess small advantages in the opening can be pretty much ignored for the most part by beginners since it'll be a major tactical blunder(s) that'll decide the game not minor advantages built up in the opening. Again, I could be very wrong! But I find these kinds of discussions about small advantages fascinating so thank you for your contribution to this thread even though my main focus at the moment is not these kinds of worries. |

Yeah, as you'll notice I didn't have anything to say either about  either; I agree that as ddk fuseki goes, it's a pretty good result. (That isn't the same as saying it's a good result! )But one reason why this is considered bad for black is that black doesn't have the corner yet; white can still invade and reduce the corner to almost nothing. In general, the Bq4/p3,Wo3/4 shape is surprisingly weak for black, wherever it occurs on the board, and more often than not W has some surprising mischief up his sleeve.One useful way to think about p3 ("the kick") --- As you know, p3 isn't locally sente; the kick forces W to play o4, but that in turn forces B to play q6, which gives W the opportunity to extend to k4. Now, what if B just played q6 directly, without kicking first? More often than not, white will respond by playing k4! At this point, does B want to take the opportunity to play the kick? Absolutely not - B's stone at p3 doesn't offer much protection to the corner, but W's stone at o4 protects against a devastating black invasion that can separate o3 and k4. Quote: ...and if my opponent neglects the extension to form a base (it happens around 17k) I have a very nice target. Don't play go like that! There are some games that strongly resemble rock-paper-scissors. Some of them I even love. (Diplomacy, for example.) Go isn't one of them. The sooner you ask "where would I play if W were much smarter than I am?" instead of "where would I play if W were much dumber than I am?", the more you'll enter into the spirit of the game.Quote: I don't think small edges for white or black in the opening really mean that much for weak ddks similar to how in chess small advantages in the opening can be pretty much ignored for the most part by beginners since it'll be a major tactical blunder(s) that'll decide the game not minor advantages built up in the opening. This is true if you mean "I want to focus more on learning to avoid tactical blunders than on playing a perfect opening." This is false if you mean, "I'm going to keep playing openings that I know are bad because it doesn't affect the rest of the game." It really does matter, even if you don't have a clear sense of how much it matters, and it especially matters to the people reviewing your games, because they're trying to look at who is winning and who is losing, and how aggressively each side has to play to stay in the game. When we look at the midgame tactical blunder, the first thing we ask is "was there a way to avoid the blunder," the second thing we ask is "was there a way to avoid the dubious invasion that lead to the blunder," and the third thing we ask is, "was there a way to avoid the losing situation on the board that made the dubious invasion necessary."

I agree completely on the latter point, I meant it as a sometimes added bonus at my level rather than as a reason to choose this response to the low approach to 4,4. I try to play the game while assuming that my opponent is better than I am and tactically this is generally true though the temptation to ignore this approach is always there and is a very bad habit that I'm trying to expunge. jts wrote: Quote: I don't think small edges for white or black in the opening really mean that much for weak ddks similar to how in chess small advantages in the opening can be pretty much ignored for the most part by beginners since it'll be a major tactical blunder(s) that'll decide the game not minor advantages built up in the opening.

I find fuseki interesting, so I devote some bit of time to it for enjoyment value, but it's not (and shouldn't be) my focus for a long time as best as I can make out. If I have a focus at the moment it's when to invade and when to reduce, as well as basic life and death, (I find myself risk adverse and very much inclined to play reductions over invasions whenever I'm unsure), though I haven't the faintest idea where to start learning about invasions other than play a lot of games and learn by making mistakes and getting reviews. |

I quite agree. Slap-dash tactics can win games, but they can become a bad habit. Assume perfect play by your opponent unless that means that you will lose.

Suppose that you make three 30 point blunders.

One of the names for go is the Long Game. You remember a few weeks ago I advised you to play as a 15 kyu. That was not a bad guess, was it? I did not make that recommendation based upon your tactics. You were still putting yourself into atari. I made it based upon your feel for the game. Several years ago I read a review by a pro in a go magazine of a game sent in by the father of a 14 year old boy who had been playing for several months and was a 4 kyu. Somewhere in the late opening or early middle game the boy jumped into the center, and it was then that the pro remarked that the boy showed promise. That was the move that revealed a feel for the game.There is a saying that chess is 98% tactics. (Probably an overstatement, eh? ) My guess is that go is about 1/3 tactics. There are many skills in go, many paths up the mountain.

Here is a thought. For one month, whenever you have a choice between invasion and reduction, invade. That way you will learn something. (I don't mean make crazy invasions, but when you have a real question in your mind whether to invade or reduce. )Bonne chance! |

I read a very good line in "How not to play Go" by Yuan Zhuo where he was analysing a game of an 8 kyu player and pointed out a bad move that led to a good outcome for the player and remarked that so long as the player kept getting this result he would remain an 8k because he wasn't learning that his moves were bad.

There are many skills in go, many paths up the mountain. Things are definitely a lot more interesting in the teens rather than the 20s and I'm getting punished a lot and not getting away with coasting along by making bigger moves than my opponent. I am getting a rather hard crash course though on dgs on fuseki and tesuji though! Myself and mus are playing our next two games as even games, the result will be very predictable I imagine but it's interesting playing on an even footing against a kgs 10k. Hard enough that I'll almost certainly lose but not so hard as to make me feel like there's absolutely no hope to pull off a surprise victory. Bill Spight wrote: Here is a thought.

In general I've been trying to get involved in more contact play just so I can get more to grips with it. I'm far too standoffish by nature and this is often wrong in this game as far as I can tell and I need to remove my fear/aversion to it by exposure. I think if I'd spent a few weeks in the mid to high 20s I'd have gotten far more used to contact play than I am at present. |
