These plays, however, don't have an enormous effect on Black. I agree that it's a hard road from having the effect of central influence pointed out, to being able to handle it competently in the myriad situations that come up in real games. That doesn't make commentary vacuous . You only have to try yourself to achieve the effects that 9 dan pros make without apparent effort, to see that none of it comes for free. A strong friend of mine is fond of the analogy of the swan swimming, where the hard work is all below the surface.
All attention is now on the upper side.
White goes into action, probing for weaknesses. It should at least be clear that once White has found an opening on the top side, the white stones to the left find their purpose in life as back-up in the fighting. It might be absurd to write off Black's experimental opening on the basis of one game, but one can say that in this instance White did find enough defects to work up a good attack, while Black took around 40 points in the two corners. Attention switches to the lower side as Black invades with 83. White on the other hand has no intention of letting Black off the hook in the centre.
