| 2010-12-18 07:04:31 | pupukani | Needs Fixing | are you sure B4 is a good move? im not sure myself but this "submarine move" can be cut, and then white will get the corner but he whill have a floating group between strong black groups. kosumi at C5 will cut. if white plays B6 then black will get the corner. did you find this in a book or something? im just interested in that move :D |
