Strange Pro Opening 5

   

I think Mr. Dinerchtein read the last entry in the Strange Openings series: the 62nd Goama newsletter featured a game between Zhang Wendong 9-dan versus Liao Xingwen 1-dan.

Fig. 1, 1-5: Double 6-4 (Again)  

Zhang opens with a decidedly non-standard pattern. I have the (rather unhappy) feeling that he plays this way because he expects it to be a bit of a crush match: an experienced 9-dan versus a thirteen year old shodan.

Andy Pierce: I've seen RoseDuke use this opening as black several times on IGS.

MarkD This opening was also used in the game Akiyama Jiro, 7d - Yamashita Keigo, 6d, B+2.5 (Komi 5.5) 30th Shinei, Round 4, 2000-02-05

Fig. 2, 5-14: An Ambitious Plan  

Through 14, I feel black has a good position. A strong player's analysis of this would be helpful, but B1 seems to work well with B7, and the bottom is well-constructed, though high. I speculate that W10 is a mistake; it looks like the sort of move strong players criticize me for.

Fig. 3, 15-24: Breaking up Housekeeping  

Black comes in at B1, and promptly uses a move I'm not familiar with to build a bit of thickness. I'm no expert, but this seems precisely what White doesn't want after having played W10 in the previous diagram. Not to mention...

...the corner is still open...

...and suddenly it seems white is coming under a stronger attack than Black. In fact, the white wall leads to essentially no territory: throughout the middlegame, it marches sedately across the dame points. In the end, it comes to six points(!).

Fig. 6: The Final Position  

Here Black wins by resignation. Once again, it's hard to judge the relative merits of the opening; hopefully, this style will be played in more even games in the future. If you're interested, the [ext] whole game is available, courtesy of go4go.

Dieter: We now have a strong player to evaluate this opening: AI.

[Diagram]
Moves 1-10  

According to ZBaduk, given 7,5 komi, Black's influence strategy - unsurprisingly - makes him fall behind by 70%-30%. Black's defence next at a is natural and White next invades at b.

[Diagram]
15-24  

When B1 invades, W2 is natural but W4 is slack. Given white+circle, a hane is natural.

Hane  

W1 is natural. Black creates influence up to B10. White can now invade at a. The weird corner enclosure makes the invasion attractive and likewise a reinforcement, which shows it's weird for a reason.

Cut  

Black can also live this way but White may again invade at W10, which is a focal point in this game.
