TG53 71 to 140
PageType: OngoingGame
Moves 131-140
Dave W131, 133, 135, 137 mat B132, B134, B136, B138 (I know ... empty triangle, but still) Dave W139 In yose there is less need to worry about ideas like empty triangles. But did you notice that it is an invitation for W to capture at 139 :-)
mat B140
HolIgor: Comment to W130. Why from this side? The group to the left becomes weaker and weaker. It will not die but now each opponent's move against it becomes large urgent sente. This will end in defending 2 points of territory while white would close the territory in the corner and in the center without any trouble. White 128 should have been answered by connecting two black groups. This connection was larger than the monkey jump.
HolIgor: I meant, for example
Connecting two groups has the advantage that the live would not be in danger and the moves against the group would not be that urgent. Allowing to separate your groups looses more than a monkey jump.
mat B132
Moves 121-130
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 W127 This is one of the interesting moves here. A B play here is sente against the corner.
After 8 (actually after 4) W is dead. As a result, W has to answer 2 at 4 and B cuts off the stone at 1. If B had played at 2 in the game any time after the two marked stones were exchanged, W could only have answered at 4. In this way B would have closed the side in sente. When B answers at 128 in the game, he has closed the side in gote.
mat B128 Dave W129 mat B130
Moves 111-120
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.
Moves 101-110
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
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 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 B98.
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
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
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 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...
