Vision attacking play 1
here is very good. White has no choice about answering at ; and Black can continue to attack the white stones on the right.
Dave: Locally what if White plays 2 at a instead? This doesn't take away one of 's liberties but it does threaten to exchange b for c next, activating the cut at d.
But really the situation of the center stones is such that wouldn't it be better to ignore and jumpt to e or at least try something like f?
The question is, how?
After playing the marked exchange, Black should shut off the lower side before pressing the attack. and here are good. Black at a is also good.
There is a problem about attacking with here. It will induce White to play at a, or b. The black framework at the top has defects.
