White is exploiting the corner aji. Black must play very carefully or else white will invade the top right and his corner will disappear.

After taking a huge lead with the tesuji 1, black has played irresponsibly.

The extension at 2, pushes around 3, attachments at 4 and 5, the push at 6 and the large extension to 7 have all given white free points or chances.
