Black has just played 1 in the diagram, White tenuki. White (much stronger player) assures me that Black can kill.
ThorAvaTahr: Good suggestion. For killing purposes the small monkey jump is usually a little bit better (but depends on the circumstances ofcourse). It is because than black is more flexible to sacrifice , it does not give white an eyeshape when is captured.
Lets have a look at some variations.
Now A and B are miai, white lives in this sequence. (Note that is necessary because if white plays there the capture of results in an eye)
Here sacrificing does not give white an eye. But white's shape is so large that it lives (by the grace of its outside liberties).
In this case white live as well
From this short survey I would conclude white lives, but surely I could mis a variation.
unkx80: I thought that this is the "standard" problem. The original problem seemed too wide to kill.
