Gochild problems, Intermediate Level, Opening 200, #20: the answer given is: Black plays at H4. But it seems to me that White can get a good result by playing G4. Then if Black blocks at G5, White can cut at H5. As Black, I would have considered H5 instead of H4. I'm not saying the problem is wrong, I am a weak player (5k). But some explanation would be helpful. |

Here's the position. Black's choices are extending from the shimari at the top, taking the bottom left corner, or H4. Of the three choices, H4 seems best because it is a pivot point of two moyos. H5 however also looks better to me... P.S. Speaking of GoChild, does anyone know what "dong-dong grouping" means? |

On second thought, maybe it wouldn't--black is getting quite a bit out of this exchange even without the possible reduction on the bottom. [/quote] |

My gut feeling is Black should now get the whole lower left corner, as well as having expanded his framework somewhat. It feels like a bit of a windfall to me - White will be hard pressed to make up for the loss in the lower left corner. Caveated by my strength anyway

In order to reveal vast questions to users of GoChild, we have tried to re-group lots of packs. Grouping is based on difficulty, from easy to hard with 10 levels. Due to large number of questions, our grouping is not perfect. Please use label function and create customize group for your convenience. We would like to thank all contributors again. Without their hard work, there won't be so many questions for us to practice. |
