Teaching Game 53
mat: OK, here's my first teaching game online... I'm somewhere around 7k. I've played some games against a 1k player with 4 stones and most of the time I lost (he doesn't give me many hints as he says he still want's to win...) Dave, how many stones do you want to give me? I want to learn, so comments and hints are very welcome and so you might want to give me less handicap... mat, when you say 7k, where is that - online (IGS, KGS, ...?) or over the board somewhere? I am 1k on IGS and 5d-6d "on the wood" in Japan. Dave mat: I'm not very sure about my rank, but I estimated 7k from my games at go clubs in germany. I don't have experiance with IGS. I've just added 4 stones - if you want to give me more add them. A game with less stones than I actually would need would give you the chance to give me some useful hints... OK? Dave OK, I am guessing that I would be on the order of 2d in Germany. I have set the board up at 2 stones to give you some problems to address from the start. At the same time we will give you a 50.5 point komi. This is something like another 4 stones advantage. One issue for you is how to think about and use the large komi. You might want to discuss a strategy first. 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...
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 teh 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 ... Anyway - as expected: I play in the open corner. I like the 4/4 point. I've got used to it in handicap games...Mat
W 3 - I'll approach the lower left. I think this direction relates more strongly to my first play than a similar play against the upper right. A quieter start would result from playing at 'a'. Both Honinbo Shusai and Hayashi Yutaro continued with 'a' after beginning with mokuhazushi against Go Seigen in the handicap games mentioned above. Against a 50-point komi, however, I will try something a little wider even if it is thinner. DaveSigaty B4 Then I do what I mostly do in this situation... mat W 5 - OK, I'll set up a framework on the left and wait to see what B will do with sente. This move has 3 elements in the present position:
If you had chosen 'c' instead of 4 on the lower side, I might have chosen another move for 5 as one of the reasons above would be gone. In addition, B's scope on the lower side would also be less after 'c' so 5 would be less urgent I think. Dave B 6 - I might have played in the upper left corner if you were less strong, but I feel I can do less wrong with B6. For a moment I thought about doing something to prevent b - but none of my ideas looked big enough. mat W 7 - I continue to divide up the board between us. Dave B 8 - me too... dividing isn't the worst thing with 50.5 komi - I hope... W 9 - Two stubborn guys, each going his own way :-) Dave B 10 - yes :-) Sure, this move is smaller than yours, but it makes me feel safer..
Bill Spight: While I agree that B 10 does not work so well with Black's moyo on the right, I respectfully differ with Dave. I like it. :-) Discussion of B 10 moved to TG53 Black 10 Discussion This is a copy of the living page "Teaching Game 53" at Sensei's Library.
