Capture Variation |
|
Circular Hanezeki We call this very special position "Circular Hanezeki". The "usual" hanezeki in the lower right corner (with , , , , and ) has become extended by Black's large group in the upper right, and White's centre group . Despite Black's group has an eye, but White's group is eyeless, the proverb of "me ari me nashi" does not apply in Black's favour here - due to the characteristics of the Hanezeki involved, which stop Black from approaching White's group successfully. |
|
Crosscut Sequence |
|
Hanezeki Exchange With the classical solution, it is necessary to play this exchange early in the game, because - without the second throw-in there - a move at 1 is sente for both sides. |
|
Hasami-Tsuke Sequence However, the hasami-tsuke of itself cannot be played without Black's push of (that White answers with the block of ) beforehand. Therefore, we understand Black's kikashi of 1 as an integral part of this sequence. |
|
Joachim's Ko-Semeai This ko-semeai is preceded by the hiki of on the upper edge, found by Joachim. There are variations, where this move is played at instead, capturing White's left side. It is also feasible for Black to insert the kikashi of , during the sequence of enlarging the hanezeki's tail. |
|
Nakade Sequence With Joachim's Ko-Semeai, we often refer to the first three move-pairs of this sequence, which generate potential ko-threats for Black that White is forced to answer in any case. |
|
Punishment Semeai |
|
Punishment Semeai Liberty Level In the main line of our solution, the Punishment Semeai Liberty Level is seven. White is unable to capture both the hanezeki's tail , and Black's -group. |
