The following diagram is what I got from Kim Sungrae's "21 Century New Openings Vol.3" (This book is currently not available in English, only the original Korean version is available and 4th volume of this book came out in Korean on July 2012). The position below(without move 1) was considered not as joseki because white's position is very good and black still has aji left in the corner. However, black's move 1 at the diagram is the modern Korean research. If white continues with a, this is what black wants so b is a more common move for white. If white tenukis for move 6, White's variation, black can also tenuki for move 3 |

Yes, it played many times in professionals games since 2008. It may be mistakenly attributed to Yi Changho, but it was played much earlier. I think most professionals now prefer first variation because it covers stone better and White build strength in good area of board -- this area very important for fighting in modern go. However, joseki are still played from whole-board view, so either can be fine. Common followups include attaching A or B to building side group or leaving for aji. If Black play this way, then White can aim good reduction corner. The reduction is worth more than White loss on side, so it's bad for Black: Therefore, Black play from corner as first variation. However, Black stone is not covered as well, so it's more difficult for White to fight with this group: So thinking is: if Black will approach from corner anyway, then White should cover marked stone from beginning. The marked exchange gives Black a little more, but covering the marked stone is more important and exchange also help White with this strategy. |

I saw that in a game, where the player attached to a stone at b. Is that to provide for future ko threats? Seems like a weird and surprising move to make. |

Seems like a weird and surprising move to make. it is a probe before the fire spread there. below  and  trade will give white a point advantage. and  trade is not necessary now because white might want to play other way.below diag is an example of black playing power move.. now white have aji of life in the corner ..i think. i thinkg correct response to is below..it is most passive move but i think it is correct. that trade itself is a good trade for black. below appears to be ok for black too. i really didnt read life and death in the corner but...i think there is aji. below is probing (asking) for a or b. a is submissive b is non-submissive (submissive doesn mean it is wrong) |
