Post subject: | A game with big weak groups |
There have not been many posts in this section recently. To fix that, here is the first of two games from the recent BGA tournament at Bracknell. This one was played against my most frequent opponent. We have met 6 times in the last 12 months. For some reason, all our games turn into large-scale life-and-death battles. Probably it's because I am a determined old man and he is a stubborn old man. ![]() particularly interested to hear how this game could have been simplified with advantage to either side. I added extensive comments to educate the double-digit-kyus and to give the dan players a laugh. I am White. Both players are 4kyu. My opponent has improved a lot in the last 6 months; I have not. His chief weakness is that he does not think long enough. At the end of this game, I had used the full 60 minutes, but he had only used about 17. EDITED to correct various typos and infelicities. |

I guess your opponent is Roger Daniel. |

Some single-move ideas, mostly suggestions for simplification: 16 @ D11 -- no weakness for B to exploit 24 @ E12 -- perfect shape 28 @ G11 -- induce B to add another stone 32 @ H5 -- run out with good shape 44 @ E16 -- keep B split, let him live small 46 @ F17 -- jump ahead, leave no weakness 48 @ G17 -- same idea, take territory, let B connect 52 @ F17 -- must capture B stone and live in corner 56 @ B15 -- shape tesuji, worth reading out 66 @ A16 -- nothing to lose, lots of decent ko threats 74 @ Q15 -- keep B separated 80 @ L15 -- sequence L15-L17-K17-L18-M18-K18-O18 86 @ J6 -- kikashi before connecting (give B two empty triangles) |
