基本图:这是在今年的全国段位赛中,笔者执黑与某七段棋手对局中出现的局面。图中白空已明显多于黑棋,但下边两子与上边几子都还未完全安定,且左右两条边空也显得有些薄。此时,对于黑棋来讲,只有严厉地冲击白棋,并获得相当的利益,才能取得全局的优势或保持全局实空的平衡。那么,黑的下一手从何处着手呢? 图一:首先使人想到的便是1位镇直接分断攻击白(?)两子,但被白2关出后,黑并无什么特别严厉的后续攻击手段。黑若B位关,被白3连回后则万事皆休。若3位镇,则白4尖出,由于白逃出(?)两子后还留有A位分断黑棋的手段,黑也有后顾之忧。 Basic map: This is the national races this year, the author of the black and a seven-segment play in the game situation. The figure has significantly more white than black, but below the two children and the above few are not fully stable, and left and right side of the two also seemed a bit thin. At this point, for Black, only white and white strikes severely, and obtain considerable benefits, in order to achieve the overall advantage or maintain the overall balance of the world. So, where does the next black hand start? Figure 1: The first thing that comes to mind is that a town directly breaks off the white (?) Two, but when it is shut out by the white 2, there is nothing particularly harsh Follow-up attack means. If the black B-bit off, after being white 3 even then everything is off. If the three towns, the white 4 pointed out, because white escaped (?) After two children also left a black break means, black also have to worry about.
