TG53 1 to 70
PageType: OngoingGame
Moves 61-70
mat B60: Thanks for your analysis of the corner, it now causes me really a big headache when I look back at B42 and B50. I considered the following hane underneath when I played B48, but due to an error in reading it out I got afraid of it.... what a pity! B60 seems natural to me, I considered 'a' as well - as it seems to secure the corner, but I was afraid of W60, Wb and Wc. I suppose you will go for the 3/3 invasion next, but at least I will be able to build a wall underneath you. Dave W61: W59 is unlikely to make sense if I follow up with a 3-3 play. When W enters at 3-3, one of the points is to try to use defects in B's position to make forcing moves that build some kind of shape. W59 "forces" B to patch the gap in his 1-space jump. In most situations (maybe this one too :-) it is a "thank-you" move that B is happy to answer. It can only make sense together with other W plays on the outside. mat B62: 'd' may be natural, but if I continue just to defend I will lose the game, so here's my next experiment
Dave W63: this is supposed to be a teaching game so I choose to set you a problem with this rather vague 63. Whatever you choose in turn for 64, I am interested in your thoughts behind it. mat B64: Isn't this miai? I threat to either capture W61 or to connect to the marked stone. This plan may be overplay in the view of my strength but I feel that the komi is nearly reached with my losses in the upper left. mat OK, now I've just seen "TG53 after W61". (Probably I should have waited with B64 and see if defending is better. Anyway I do not withdraw a move and will spend some time for your question now) Dave W65 I will respond to your move before looking at TG53 after W61 :-) Your 62 and 64 look too thick to fool around with. I have to strengthen my framework. It is worth considering what W would have done if you had played 64 at 65. It looks like I would have been unable to stop you from breaking into the upper side. W63 may have been a mistake on my part. mat B66 I am happy to hear that you wont 'fool around' ;-) Dave W67 This seems inevitable... mat Let's make things complicated... Dave OK! mat Hey, why don't you do what I think you are going to do? Maybe I need a new plan ;-) However, B70 was obvious...
Moves 51-60
Dave W51 Let us see what you make of this. mat I hope that works... Dave Funny, I am hoping the same thing about mine :-) mat OK, B 50 might have been wrong. However I'm not going to die! Dave Let's settle things a bit and then take a look back at the corner. W55 mat B 56 can't be wrong. Dave W 57: unfortunately 56 is almost certainly wrong. B has been tricked here (or has tricked himself). W57 is very big; W has blocked on both sides and the corner is not alive yet. mat Hmmm, I thought I made my mistake earlier... If I had played 57, you could have enclosed me below and instead taken the upper two stones. Is that a big difference? Anyway: B58
Dave W59, the upper left has stabilized and W has sente. Kitani Minoru's teacher, Kubomatsu, used this maneuver against a B one-space jump to expand his moyo in a 3-stone game played when Kitani was 13 years old. I have always wanted to try it :-)
Moves 41-50
Dave, if this game would be continued by two players of equal strength (and with normal komi), white would win, wouldn't she? At what time has black lost the advantage of her two stones? mat Probably it might be instructive for me if you (or anybody else) could give a short analysis of the current situation. I find it very difficult to learn when action and feedback (in terms of territory/life outcome) are separated by lots of moves mat Dave: OK let's look at the situation - TG53 After Black 40. Dave: Meanwhile back at the game... W41 (too blunt for a teaching game?) mat: B42 (Initially I was aiming at the outside, let's see if I will get there in the end...)
Dave: W43 OK, let's see what I can do to prevent it :-) mat B44 you must have expected this... Dave W45 it was the most likely... mat B46 so was mine... See you in two days, I'm leaving for a short trip! Dave In a position like this you should also consider playing 46 at "a" or "b". If B wants to push downward from the corner, the cutting point at "b" in the game is a problem. W 47, W closes the open skirt at the top.
mat B48 Hmmm, I'm in an advanterous mood today. I can't read it out to the end, but I feel that the possibility to connect either near the border or to help a breakthrough in the center is a good thing (miai?). Do you go to 'f'? I think 'g' is a good response to 'f'. Probably you will go to 9 - then 'f' maybe my response. It is interesting to play that way. The second time I look at a situation I change my mind very often!
Dave I will try W49
mat B50 (as announced)
Moves 31-40
W 31 - Good luck! You may be trying too hard here (then again I may die :-) That's all for me today so read it out at your leisure. Dave B 32 - Do I have a choice? I don't want you to cut at 'a' with atari, so I can't let you get B32, so I have to get it instead. I am weak at reading (the other player often chooses moves I didn't think of) so I like this sort of "mental shortcuts"... I think you will continue with 'b' and so far I think I go on with 'c' Unfortunately I will not have internet access during a journey that I start tomorrow. Maybe we manage one more move until I leave, then there is a break of 2 weeks. Sorry for that, I'm looking forward to continue.
W 33 - I will play toward the corner. I am a little busy tonight with the family so I may not be able to play again if you answer. Why don't we stop here and you can take the situation away with you on your trip, think it over, and decide what looks good to you next? There is no hurry. See you when you get back. Dave B 34 - I will defend the corner (internet is everywhere!) I think I might be able to stop you somehow if you go further up, so the lower side might be more important... W 35 - I will descend here, I think it keeps more options open for me. Dave B 36 - OK, tenuki (I'm home again) mat W 37: Welcome back mat! How was the trip? Dave
B 38: In this phase of the game I usually start to guess a lot. Should I have tried to connect 36 with other black stones on the right? should I make an invasion into the upper left corner / upper side? I don't know really how to judge the value of those moves...
W 39: I receive you from the outside. What plan do you have or what plan will you create :-) B 40: I've wanted to play in your corner for some time. I can't see if 'd' or 'e' is better. I decided to go for the outside since that may work with B38 and B36 (although I have no precise idea how). All I try to do here is to destroy some of your territory...
What do you think about the exchange in the bottom? Black is overconcentrated on the left, has peeped at a bamboo joint and even tried to cut it. As for White, he has made an empty triangle.
Instead of peeping and trying to cut a bamboo joint, the keima (marked) extends into the center and threatens White's group. White still has the empty triangle.
Moves 21-30
W 21 - I will connect. However, you need not continue as below if you have changed your mind in the mean time (although it may speed things up it may also defeat the purpose of a teaching game). Dave (ps: Bill, I didn't have the nerve to claim the generic "Dave" for my very own. But since you did it for me what can I do except accept, thanks :-) OK, I changed my mind. Normally I try not to follow the hints of others (although I read them carefully), since I want to learn rather than win. But B22 is "my" move. I may have chosen it anyway. Looking at the stones on the board is different from thinking over it ;-) However I think it is good for a teaching game to say what I have planned. So: I think you will connect at a (3) and I think I will connect at b (4). I'm a bit afraid of your possibility to move at b (4), I can't overlook what will happen then (probably I'd go to 'c') W 23, B 24, W 25 - OK, let's play it out and see what happens. I will continue by attaching at 25 to see how you will react in the corner. Dave B 26 - I'm weak at josekis but that looks reasonable... W 27 - One continuation B 28 - W 29 ...
W 30 ...
Moves 11-20
W 11 - I chose tengen partly as one of the key points between the W and B moyos under construction. However, I am also thinking about the usefulness in supressing/invading B's right and bottom as mentioned on IGS 5k Against Low Chinese. B 12 - OK, I'll try to play wider. B 12 is good for both wings and as far as I can judge, it somehow makes B10 look better. Furthermore, it should help me in the center, too. I thought about playing (a) as it attacks white and makes my influence better, but I wasn't so sure if it would really be sente, so I chose B12 (B12 isn't sente either, but I feel that it is bigger)
W 13 - Let's see what you do with this. Of course I am trying to punish B 10 and the availability of the shoulder hit is one of the things that I didn't like about it. Dave mat: You call it my best move so far? Is there a problem with B2 to B8? Well, I'm glad you liked B12.
B 14 - I don't have much choice, have I? I'm not "brave" enough to tenuki and 'c' might give you the opportunity to push against my moyo in the lower left and at the same time locking up your huge moyo, so B 14 is the only move I can think of.
W 15 - trying to play quickly and lightly, looking at the center or the bottom depending on how you play. By the way, if I had played at 16, what would you have played? Dave B 16 - OK, I will try to cut. To be honest, I don't know what I would have answered to W16, probably tenuki (when in doubt...) Is my overconcentration result of B10 or could I have played B14 elsewhere?
B 18 - as expected W 19 - The normal solid connection would leave behind a B splitting play at 'e'. This 19 looks at the relationship with the stone on tengen. (It is bed time in Tokyo, you can choose your next play at your leisure. CU tomorrow!) Dave B 20 - If you connect, I might play at f
Moves 1-10
I start with 1 at mokuhazushi. It is an asymmetric move. In a two-stone game I expect that you will want to play first in the open corner so that I will then have the choice of playing again to exploit my first move. Dave Hmm I've never played with that much komi. I think I should play just a little bit more defensive to make advantage of it - just as I would have done with more stones. I can't think of any more specific strategy right now (perhaps later). I have just read your page about mokuhazushi ...
