The game that Weiqi Tiandi focused on was last year's 3rd place playoff in the Fujitsu Cup. This began as follows, Chang Hao taking Black against Liu Xing (Chang won).
Instead of 10, White could have played the boring move at 12. If Black then answered as in the game, White would have had the freedom to play anywhere he liked on the lower side - and he would hardly choose 10, would he? We may assume, therefore that White feared that a move at 12 for 10 would have been met by the block at 14. Black's resulting position obviously has a good relationship with Black 9, so we may further assume that White 10 was an attempt to pre-empt this block.
So the question is, what if Black tries to preserve his focus on the right side by playing at 1 in the next diagram?
The pro assessment of this position is that if both groups now proceed to live in the corner (i.e. even stevens there), White's outside thickness is much better than Black's.
Can Black find a better way to handle the corner? Apparently not. The following line can result in a ko, but this would be a picnic ko for White, who already has excellent returns from his play.
It seems therefore that Black has to try something different if he wants to play this Black 1. One suggestion, but not considered good in this position, is:
If Black doesn't play in this area at all after 1, then of course a White play at 8 is superb.
