is not needed to capture the W stone at J18 -- W does not have enough liberties to save this stone. So B can just capture the other two W stones to live.

| Post subject: | Live or die. From a game. |
I played this last night at club. I'm black. Comments are welcome, but mainly I'm posting this for the interesting variations at move 63. I recommend you treat moves #56, #62, and #63 as problems (i.e., try to solve them before looking ahead in the game). #62 has kind of an obvious working (?) solution that I didn't find because I was concentrating too hard on failing to read out the complicated thing... |

25: If you play G14, the whole invasion question never arises. 41: To speak of 'the wrong invasion point' suggests that there is a right one. I'm not so sure such a thing even exists. Does black really want to try living down there? How about reducing? Something like L15 looks better. Beyond the whole question of invading or reducing, how about C2? It is way bigger than it looks at first glance. 49: I agree that M16 is premature, but so is O18. They are both aji keshi. Black has to decide which group is more important, and then delegate the second group to the role of sacrifice to help keep the first group alive. Assuming that black chooses the K17 group, I think that he should push at H16 first, and leave open the possibility of L15 or M16 to complicate white's problem of keeping J16/K16 alive. |

@mitsun: arghhhh! @Joaz, Yeah, I thought of 25 @G14 after the game, but then white would make a base on the side. I'm not sure now. For 41, I think I should have played 4th line. P10 is also bigger than I thought it was, it threatens white. 49: white was trying to avoid me getting a stone on L15 in sente, and we came to the conclusion that if I cut, white either had to allow that or a ko. |
