Post subject:	Attatchment Tesuji
Hi, I'm currently studying tesuji with the help of Tesuji by James Davies. Sadly, from time to time I do not even get the explanations Here black is to play. The solution says black is to play the attatchment tesuji a, threatening the driving tesuji at b.

White would get pushed around. Click Here To Show Diagram Code [go]$$c white tenukis $$ --------------------------------------- $$ | . . . . . . . . . . . . . . . . . . . | $$ | . . . .

And frankly, I do not get it. If white plays 2, the driving trsuji does not work anymore.

W has more blighted stones, no?
