Teaching Game 53
PageType: OngoingGame    

mat: OK, here's my first teaching game online...

I'm somewhere around 7k. 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 121-130

[Diagram]
Diag.: Komi 50.5 points

Dave W121 I'll continue up the side. W123 to finish off.

mat B122, B124

Dave W125 I'll pick here next.

mat B126 That's the sort of playing I don't like ;-) I can't defend all the time, but do I have an equal threat? (you probably wont tell me...)

Dave Of course I won't tell you (partly because I don't actually know :-) But we will be able to look at it later.

Dave W127 This is one of the interesting moves here. A B play here is sente against the corner.


Moves 111-120

[Diagram]
Diag.: Komi 50.5 points

Dave W111, 113, 115 (forced)

mat B112, B114, B116

Dave W117 what's big? what's fast?

mat would B116 at B118 have been bigger?

Dave after B114 W115 there is bad aji in the center for W (B at "a" threatens a big ko). As a result the W hane at 116 is less of a threat than it was. W117 is not necessarily the biggest move in an absolute sense but it threatens a wide open B territory so B seems to have to answer. Probably B116 at 118 was best.

mat B120 I don't think anything tighter will stop you.

Dave You are probably right. The reason is the exchange of 118 for 119. W119 protects the point at "b". If 119 were not there, you would be able to play at "c" or "d", for example, and stop W more tightly than in the game.


Moves 101-110

[Diagram]
Diag.: Komi 50.5 points

Dave W101 I'll push into your area in order to reduce it but more importantly to prevent you from forcing me to remove your stones at the top.

mat B102

Dave W103

mat B104

Dave W105 Now it gets tense again!

mat yes: B106

Dave W107, W109

mat B108, B110



Moves 91-100

[Diagram]
Diag.: Komi 50.5 points

Dave W91 The one-way street continues...

mat B92

Dave W93 Now we have choices. Does this one work? Who is in more trouble here? :-)

mat I honestly don't know (I suppose you do), I guess I can get a ko if I do not make a mistake... This time I will not communicate my thoughts, since that increases the likelihood for you to exploit an error of mine ;-)
Dave I think this is a very complicated position and I really don't know what is the status. It will be interesting to look at alternatives later :-)

mat B94

Dave W95 I'll take this point.

mat B96: my first eye (nearly) (W95 was again a surprise!)

Dave W97 I don't know that 95 was the right approach. In theory when you played 92 without atari at 95 I should be happy to let you capture 89 since then 92 would become essentially a wasted stone. On the other hand trying to read out the fight if you broke out into the left was giving me a headache! :-)

mat I was looking forward to the breakthrough...

mat B98.

Uhhhh I think this was a mistake. If you want to let me withdraw it, you can put B98 to a. Otherwise I wouldn't be surprised if you go to b...
Take your time and decide which you prefer. I'll wait for you to clarify your choice. Dave

mat B98 I give up this fight! If I play a you can answer with c, if I play c you can answer with b. All I can do is to clear up a bit in sente. What a pity!

Dave W99

mat B100 I feel better with this stone.



Moves 81-90

[Diagram]
Diag.: Komi 50.5 points

Dave W81 One way or another this should decide the game shortly.

mat B82 Let's get one point of liberty in sente

Dave W83, 85, 87, 89...

mat B84, 86, 88, 90...



Moves 71-80

[Diagram]
Diag.: Komi 50.5 points

Dave W71

mat B72 I really want to play 'a', but since B72 is sente I hope it's not a mistake. I do not dare to think that it works, but I'll try.

Dave W73 Let's see if you can make it work :-)

mat B74 This time I was able to predict your move ;-) ! Of course I have to play B74 if B72 was to make sense...

Dave I didn't originally plan to answer 72 with 73. When I settled on 71 I thought that I would have to compromise with a play at W76. But at the last minute I thought, "What the heck, this is a teaching game; maybe we will both learn something!" Somewhere in The Direction of Play, Kajiwara writes that if an attack won't work, better not to start the attack. The problem with us amateurs is that we lack the skill (or are too lazy) to properly read out the result. W73 may or may not be an overplay. Unfortunately the play of a couple of ??? (BTW what is the Go term equivalent of patzer in chess? no offence intended!) probably won't teach us the true result anyway :-)

Dave W75 will this hold it all together?

mat B76 Hmmmm, either I connect to B68 or B78 will let me destroy a bit of your territory. I'm not so sure about the latter one...

Dave W77 Naturally I can't let you connect so easily. So let's see how much damage you can do to the top...

mat B78 Here we go...

Dave W79 I think this one really is inevitable :-)

mat B80 this looks good...
