Round 9, AT, WC

Dai Xiaohan(B) vs. Vladimire Sushkov(W) Black wins

Original: ShowPost.asp?ThreadID=14808

I2 is the most common opening in this WT. I2 is generally balanced under Yamaguchi Rule. The variants are many and complicated. The number of 5's alternatives are 6 to 8, most common 7.

Sushkov leaves this 5. At the first glance, 5 doesn't make a 2, and only limits 2-4 to a certain extent. However, 5 prepares to accumulate black's strength. Once black takes initiative, 5 would help black to be at great advantage. As popular saying goes, "2" is essential at the beginning. White starts to make twos. Seeing 6, my first thought was to respond at H10 to block the current two and to interfere the future ones. Below is the analyse on 7-H10. You can see that black cannot be much stretched.

Here goes the real game. Dai's 7 cast mine into the shade immediately. Renju emphasises on efficiency. 7-G10 connects 3 and 5, and develops 5. If 8 and 10 play like this, 11 can also make a three in return.

In the real game, 7 determines the victory of black. Black and white both attack feriously. After 12, black gets the initiative and makes VCT on the left side until 27. 27 is a skillful move.

In my opinion, the cause of white's failure is the neglect of the 7. It confirms that the opening is the root of a game.

Very strange comment, first of all, this opening is I2 and not D2. Secondly, there is no way to balance this opening. If one opens it with 7 5th moves, it is better for black no matter which 4th move white plays. If one opens it with 8 5th moves then in case of 4 -H10 it is white advantage. Sushkov trusted another Russian player who had told him that in I2 black has no win in this variant. Very stupid. He could have just asked me and avoid an embarrassing loss.

Sorry for my fault. The opening is I2. The original writer was right. Thank you for correction.

As for the technical issues, discussion is very welcome.
