3-3 and a 3-4 black
Anthony Burzillo states that this is the most common opening starting with a 3-3 point:
Velobici: Is this actually the case ? How did you determine this ?
Anthony Burzillo: on fuseki.info, it shows this opening as the highest percentage of winning for black.
Tapir: In my database this is actually not the case. The other 3-4 point has a better winning percentage. + The exact configuration with the White stones is pretty uncommon = too uncommon to draw conclusions from the winning percentage. The Kajiwara Sakata game given as an example is the only game I have where Black wins after playing . Not what I would call a standard opening.
