| Sharp pattern in Indirect 12 | 2009-01-09 00:26:41 |
Dear readers! Please write your opinion about the next variant:
|
|
It seems that after 5 this pattern is *almost* forced for both sides until 28.
After 28-e4 black has the good development 29-i5 30-j4 31-g11.
The opening i12 + 4-j8 is not proper for Soosyrv rules since black has four 5th moves with an advantage: 5-e8,f7,h10,k7. The move 5-h6 seems to be the fifth 5th move by strength. So, this variant is proper for Taraguchi rules.
This variant can appear also after another 4th move 4-h10:

After 8 we have the same position as at the previous diagram. The move 4-h10 is not proper for Soosyrv rules too since black has four moves with an advantage: 5-e8,f7,h5,j8. The move 5-h6 seems to be the fifth 5th move by strength. So, this variant is proper for Taraguchi rules.
It is possible to obtain the same position by one way more:
|
|
However, after d11+ 4-h10 black has five 5th moves with an advantage:
5-g7,f8,e9,g9,g10. So, this 5-moves position is not proper even for Taraguchi rules. Nevertheless, it is proper for Sakata rules.
Dear readers! It can appear that I made a mistake and in this variant some side can obtain an advantage or even win. If you find this please write just here in comments. |
ADDITION. It appears that black has more strong 11th move:
|
|
Black takes an initiative here.
Such 11th move is even more strong after 4-h10 5-i6: |
|
| The last variant is especially important since it gives advantage to black in the case of five 5th alternatives after 4-h10 in i12 and i8 openings. So, 4-h10 in i8 and i12 is improper even with the Taraguchi rules. |
